For long ranges Mk12 MOD1

46



Special purpose rifle Mk12 MOD1 belongs to the family weapons AR-15 / M16. It was originally developed for U. 5 units. SOCOM (Special Operations Command). The self-loading rifle, which uses a scheme with the removal of powder gases, is used by the US Marine Corps in Afghanistan to hit targets at ranges up to 800 m.

In Iraq and Afghanistan, the rebels are leading a guerrilla war against local security forces and coalition troops. Rebel tactics - surprise ambush attacks. However, they often make only a few shots from long ranges and then depart. Rebels often use civilians as human shields. This behavior makes it almost impossible for the security forces to respond with fire, as there is a threat to the civilian population and this causes collateral losses.

The assault rifles used in the coalition troops, such as the Bundeswehr G36A2, the British SA80A2, the British armed forces and the M16A4, and the M4A1 US armed rifles simply do not have enough accuracy to defeat them to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to defeat them, to beat them. In response to this state of affairs, coalition forces began to acquire the so-called "rifles for selected apt shooters." They were then accepted for use by troops participating in operations in Iraq and Afghanistan, at the level of a detachment or platoon and were given the best shooters, which thus became the "selected marksmen". “Selected marksmen” are not snipers, they are those who, thanks to the best weapons, are able to confidently hit targets that their comrades cannot hit.

In 2009, the United States Army adopted an improved rifle, the M14, chambered for the 7,62x51, as a rifle for "selected apt shooters." Recently, the British army began to issue At the branch level sniper rifle L129A1 chambered for 7,62x51. In the Bundeswehr in the framework of the coverage of "immediate needs related to the conditions of hostilities" several G3 assault rifles chambered for 7,62x51 cartridge were converted into "rifles for selected apt shooters". The US Marine Corps already in 2003, took a special-purpose rifle Mk2 MODI chambered for 5,56x45 as a weapon for apt shooters.

Designed for special forces

The special-purpose rifle Mk12 MOD, like its predecessor, the special-purpose rifle Mk12 MOD0 belongs to the AR-15 / M16 weapon family. It is an automatic weapon caliber 5,56x45, using the principle of removal of powder gases. Originally, rifles were designed to meet the needs of the Navy and Special Forces units of the US Army in a new self-loading sniper and high-precision rifle. History The development of this weapon can be tracked, starting with the Special Operations Peculiar Modification Kit program developed in 1990-ies (SOPMOD, abbreviated as “Modification for the Special Operations Forces”). The SOPMOD kits consisted of sets of units for retrofitting the M4А1 carbine, with the installation of which the weapon, previously used only by special units, could be adapted for special conditions of use. When using retrofit elements, the possibilities of aiming and identifying the target are improved, the reaction time is reduced and the accuracy of shooting is improved both in the near zone and when using weapons at ranges to 600 m day and night.

The first SOPMOD kits were issued to the troops in 1995 and included the following components: ACOG-x4 sight, laser AN / PEQ-2A laser / light module, mounted 40 mm M203 grenade launcher, silencer, night sight AN / PVS-17A, tsevё s four Pikatini strips according to the military standard MIL-STD-1913.

As part of the development of the SOPMOD kit program in the Crane division of the Land Forward Operations Center of the US Navy, they also thought about installing the MXXUMX4 carbine into a sniper rifle by installing retrofit units. In the future, an independent project grew out of these plans, which led to the creation of special-purpose rifles Mk1 MOD21 and Mk0 MOD12. At the beginning of the 1, the first Mk2003 MOD12 SPR rifles entered the units of the US Special Operations Command (SOCOM). In November of the same year, the Mk1 MOD12 SPR rifles were issued to units of the US Marine Corps that participated in operations in Iraq and Afghanistan.

The weapons for the US Marine Corps are produced by the High-Precision Weapons Section of the training battalion located at the Marine Corps Base in Kwaitico, Virginia. In order to achieve the highest possible accuracy and to keep manufacturing tolerances as low as possible, components from only certified manufacturers are used to manufacture weapons.

Technical features

The special-purpose rifle Mc12 MOD1 caliber 5,56x45 in unloaded form, as a silencer, as well as with a Leupold Mk4 rifle scope 2,5-8X36 weighs 5,5 kg, is 184 mm in height and 82 mm in width. The length of the weapon without a silencer is 946 mm, with a silencer 1067 mm. The theoretical rate of fire without a muffler ranges from 625 to 650 shots / min; with a silencer, it rises to 775-800 shots / min. Although from the 12 MOD1 you can also fire in short bursts and continuous firing, it should be mentioned that it was not intended for this.

Trigger box

For the production of the first Mk12 MOD1 trigger boxes, the boxes from М16А1 were used, and the Mk12 MOD1 of later production was based on the М4А1 design. They are equipped with two-stage match trigger mechanisms. With warning and descent force 2 kg. production company Knight's Armament. In addition, the trigger is equipped with a new trigger. In addition to the “Protection” position, the safety lever can also select firing modes - “Single” (single designation) and “Continuous” (designation Auto; on some frames, instead of Auto, marked Burst). The shop window is unmodified, and for the Mk12 MOD1, the same 20 or 30 charging stores are used as for the M16L4 or M4D1. The frame and shoulder rest are used the same as for М16А4.

At the compound level in the Marine Corps, the individual Mk12 MOD1 are completed with a Magpul-type retractable shoulder stop MY Stock - Mil-Spec, manufactured by Magpul Industries Corporation. The shoulder rest has a rubberized butt and the adjustment range 83 mm (four installation steps).

Receiver and receiver pad


"Multiplication table" for the shooter: using the Mildot-Master counting ruler, you can calculate the firing range and decrease the trajectory


As for the receiver, bolt carrier and butterfly valve, here we are talking about the standard components of the rifle M16A4. but still, parts with particularly small manufacturing tolerances are used, which are subjected to additional testing by increased pressure and are finally checked for the presence of cracks on the magnetic flaw detector. On top of the receiver is the Picatini plate according to the military standard MIL-STD-1913. By replacing the conventional cocking handle with a DPMS Firearms, LLC, the PRI M84 Gas Buster Charging Handle has improved weapon safety. The new cocking handle has an ergonomically improved locking lever with a larger surface for fingers. In addition, this cocking handle better than the previous closes the receiver and prevents the gunner from flowing gunpowder gases and oil particles from getting into the face of the shooter. A construction called the Rail Adapter System Free-Floating Barrel (Long) Model 21318 (long adapter with guide bars; freely oscillating barrel), which is actually the forend, is manufactured by Knight's Armament and has four Pickatini strips of military standard MIL-STD -1913 length 286 mm each. Along with other components, a front sling is installed on the slat under the belt for wearing.



Front: The folding fly from Knighfs Armament is located at the front end located on top of the Pictini bar's forearm.



Behind: The folding sight of the Mk12 MOD1 SPR rifle, also produced by Knighfs Armament, is a mechanical sight.



Reducing: when firing without a silencer, a reduction in recoil and tossing the muzzle provides a compensator



Dimensions: with a Leupotd telescopic sight and a silencer, the McNNXX MODI SPR rifle is 12 mm long, 1067 mm high and 184 mm wide


Trunk

The Mk12 MOD1 rifle has a long, free-swinging barrel with six right-handed grooves; rifling pitch - 7 inches (178 mm). Barrel length is 472,5 mm (18,6 in). The special shape of the barrel improves heat dissipation and firing accuracy while reducing weight. The barrels for the Mk12 MOD1 are manufactured by three different companies: Douglas Barrels Incorporated, Lewis Machine & Tool Company and Barrel Barn. The gases are evacuated with the help of a gas block installed on the barrel, which is produced by the Crane unit of the US Naval Warfare Center on land.

Sighting device

The Mk12 MOD1 SPR rifle uses a Leupold Mk4 2,5-8x36 MR / T М2 rifle scope with Tactical Milling aiming mark. The aiming mark can be highlighted. The stable, waterproof sight weighs 454 g and has a length of 287 mm. The sight is optimized for use in twilight, and allows the shooter to clearly distinguish between contours and targets, even in low light. To eliminate glare, the sight has flip-up lens and eyepiece covers. The vertical and horizontal adjustment range is 90 angular minutes. Adjustment is carried out by "clicks"; The price of a “click” is 1 / 4 angular minutes. The sight is mounted on the Picatini rail of the receiver with the help of mounting rings from Atlantic Research Marketing Systems Incorporated. In case the telescopic sight is damaged, the Mk12 MOD1 SPR also has a mechanical sight, which consists of a folding diopter pillar and a folding front sight, also produced by Knight's Armament. According to the Service Manual, mechanical

the sight is designed to use weapons in the range from 200 to 600 m. Adjustment screws on the rear sight allow you to adjust horizontally and vertically. The rear sight, like an optical sight, is mounted on the Pikatini bar of the receiver, the front sight is in front, on the Picatini bar of the forearm. Pikatini slats on the forearm of the Mk12 MOD1 SPR rifle allow you to additionally install various sighting devices or night vision attachments, for example, the AN / PI-Q-2A Aiming Light laser target designator or the AN / PEQ 16A Laser Integrated Light Integrated Pointer Illuminator Module (M1PX) ) - “Integrated minimodule of target indication and illumination”.

Muffler and fry

The Mk12 MOD1 SPR rifle is supplied with the silencer of the 12 model SPR'iVIBS 5,56 mm Precision Suppressor. This silencer is manufactured by OPS Incorporated. He simply screwed onto the compensator located on the muzzle of the rifle; cuff, advancing on the trunk, is used for centering. When firing without a silencer, the compensator provides a reduction in recoil and toss the muzzle. Due to the removal of powder gases to the sides and upwards, it also prevents the formation of clouds of dust when firing. The hole in the muzzle of the compensator is 0,762 mm larger than the bullet diameter. The silencer has a length of 216 mm and diameter of 38 mm. It is made of explosion-welded 300 alloy steel. According to the manufacturer, the muting efficiency of the sound is 40 dB.

Bipod rifle Mk12 MOD1 SPR is a model HBRM-S company Harris Engineering. Its supports can be extended from 153 to 228 mm with 25 mm pitch. The hinge integrated into the base of the bipod, the rotational force of which can be adjusted, allows the shooter to eliminate stall rifle on an uneven surface. Installation of the bipod is carried out by Knight’s Armament’s mounting plate on the lower bar of Pikatini forearm.

Affiliation

Special purpose rifle Mk12 MOD1 SPR is supplied in a waterproof and dustproof, impact-resistant Pelican-1700 weapon case. It is made of black, exceptionally impact polypropylene copolymer. The case weighs 7,7 kg, has a length of 968 mm, a width of 406 mm and a height of 155 mm; the internal dimensions are 908 mm in length, 343 mm in width and 133 mm in height.

A rifle cleaning accessory is supplied by Otis Technology Incorporated; It is in a convenient nylon bag with a zip. Along with the other components, the cleaning kit includes a Memory-Flex cleaning cord, a rag holder and various barrel cleaning brushes. In addition, for intensive cleaning, a nylon-coated ramrod and ramrod guide are supplied with a rifle.

The documents that are delivered to the troops along with the rifle include the “Mk5,56 MOD12 TM1A-OR-l Special Purpose 11416-mm Rifle Manual”, which describes the maintenance and handling of the rifle in detail. It is attached both in print and in electronic form, on CD-ROM in pdf format. The form documents the accuracy of shooting.

Attached to the scope of the operation and maintenance manual, as well as a description of the aiming brand Tactical Milling. The Mildot Master calculating line is very useful, with the help of which, using data obtained from the aiming mark. you can quickly and easily determine the distance to the target and lowering the bullet relative to the throwing line. Equally useful is the table with ballistic data.

Ammunition

With a special-purpose rifle, the Mk12 MOD1 can be fired with all 5,56x45 caliber cartridges, which are accepted by the US military. Especially for use with this rifle, cartridges are issued with a special 77-faceted (5 g) long-range bullet Mk262 MOD0 / MOD1 АА53 (77 gr Long Range Special Ball Mk262 MOD0 / MOD1 AA53). These cartridges use an 77 facet bullet with a cavity in the head and a tapered shank (NRT). In the production of Mk262 MOD0 cartridges, Sierra Matchking bullets from the Black Hills Ammunition are used. The McNXX MOD 262 cartridges use Sierra Matchking bullets from both Nosier Incorporated and Black Hills Ammunition. The National Defense Industry Association (NDIA) declares the accuracy of these rounds at a level less than 1 angular minutes. When firing these cartridges from an assault rifle M1A16 or a carbine M4A4 reach accuracy in 1 angular minutes; standard infantry cartridges of the US Army M2 achieve accuracy only from 855 to 3 angular minutes. According to the Service Guide, when using Mk5 MOD262 / MOD0 АА1 rounds, the Mk53 MOD12 SPR rifle can confidently hit head targets to the 1 distance and height targets - to the 600 m. of their Mk800 MOD12 SPR rifles in Afghanistan are stably neutralizing targets at ranges over 1 m.

    The special-purpose rifle Mk12 MOD1 SPR is delivered in a water- and dustproof, shock-resistant weapon case “Pelican-1700”.
    if the case’s properties were extended to it. The rifle itself for shooting in the shooting range is interesting. In Moscow, with something like this (match Orsis http://www.orsis.com/production/catalog/1829/86045/) you can shoot in the DOSAAF shooting range on Poklonnaya.

        50 years ago, ours created the usual self-loading and fastened on it a not very high-quality sight. NATO had this ....... in abundance- FN FAL, G-3, M-14 ..... And optics are hung on any of them, which they always did (it turned out to be a Marxman). But ....... in addition, they did and are doing normal snipers with a bolt bolt hung by the barrel. For the sights and say nothing at the same Germans they were six times in the war and with better lenses. In SA, one could only dream about it. ===== By sabzh, as always made candy. About fragility - Chris Kyle fought with her (not only with her) in Iraq. By the way, there he had four oars with optics. :)

        Accurate shooting ??? So the tolerances and gaps are already narrowed or nullified, which boils down to a beloved song about reliability.

        The Sierra # 9377 bullet used in the Mk262 cartridge when fired from the Mk12 retains supersonic speed at distances of up to 700 meters with an energy of ~ 320J, whether you like it or not. Unlike the M4, in which a lighter bullet goes to subsonic and loses stability at a distance of half a kilometer.
        I am not even talking about corrections for these distances - horseback enough.
        Why did they choose their cartridge for the rifle - xs, since the same .308Win flies to this distance with an energy that is three times higher. Perhaps the question is the unification with the weapons of the rest of the military.

      For thoughtful shooting, the AR-system reliability is enough. Then they have sniper weapons of every kind and different for their eyes. Semi-automatic / automatic machines are considered to be the weapons of a separate sniper / Marxman.

    It's right. Do you need to combine the qualities of an assault and sniper rifle? Better than the 7,62mm SVU-AS there is nothing here.

      Some time ago, the opportunity presented itself to "talk" with the "commercial" M-16, which was purchased as a hunting weapon. The main difference from the combat model is the impossibility of auto-fire and a magazine for 10 rounds.
      The impressions are contradictory, the rifle itself, due to the abundance of plastic and light alloys, seems to be "toy", the sighting devices and the platoon handle are very unusual. At the same time, it is very practical and has a soft recoil. There were no delays when shooting fifty Russian-made cartridges. In accuracy at 300m, it is comparable to the Sobol carbine of the same caliber. The cleaning after the shooting made a great impression; I have never seen such small weapon parts during disassembly. I would not dare to disassemble it myself.

    What can be said about this sample ...
    1- Concept.
    The concept is not new, in evidence, the adoption of the SVD in 1963 into service with the USSR SA. In fairness, this revolution is more correctly called not a sniper, but, for example, a rifle with increased accuracy.
    2- Appointment.
    The article states that this rifle serves to hit targets at ranges greater than the range of the actual aimed fire of the regular trunks, that is, starting from 400 meters. Perhaps the same M16 with a good aimed sight, in the hands of a craftsman carefully crafted, can guarantee a hit by force and from 500 m., only all these conditions are unlikely to be found in large numbers among soldiers. By purpose, the difference between this trunk and sniper is also manifested. With this rifle they shoot at ALL remote targets that cannot be hit by a regular assault rifle. The main task of snipers is the defeat of the SELECT, special goals - command staff, machine gun and art calculations, etc.
    In general, the machine gun can handle the tasks that are assigned to this rifle, but the machine gun may not always be near.
    3- Cartridge.
    I think the choice of an intermediate cartridge is not entirely justified. It seems to me that rifle-machine gun cartridges are better suited for such barrels (as intended), in the case of NATO-308 Vin.
    4- Construction
    I share the doubts of the comrades expressed above. The barrel is based on the M16 with all that it implies. And well, if the main theater of operations for this barrel were a region with less dust, then the barrel was developed directly for shipment to Afghanistan and Iraq .... On the other side, the Americans, although tormented, have long been fighting with their emka.

      Right. By the way, there is a professional here who ever used a domestic 7,62mm AKM assault rifle with an optical sight mounted on it. What are its capabilities in the accuracy and slaughter board over long distances. Can AKM + OP be used as a sniper rifle? The bullet is pretty heavy.

        Once again, I can throw a video about shooting from AKMS at 460 from the front sight, but I think it's not worth it. In general, a shot machine with optics can easily master 600 m.

              Shooting at 400 meters is the usual standard in the SA and then in the RA. By the way, the target is in the belt clip.

    “However, they often fire just a few shots from long ranges and then retreat. Often the insurgents use the civilian population as a“ human shield. ”This behavior makes it almost impossible for the security forces to respond with fire, as there is a threat to the civilian population and this causes collateral losses "

    Here's something soooooo it seems to me that civilian casualties concern Americans solely because of legal aspects

        Americans have three gradations - Sniper / Marksman / Sharpshuter.
        Sniper - specially trained and trained single and pair arrows, with skills:
        - precision firing,
        - methods and methods of applying camouflage on the ground,
        - penetration into the rear of the enemy,
        - subversive training
        - battery life without the support of other units.
        They work either independently or in conjunction with other snipers.
        As weapons, rifles, rifles, are static on the battlefield, camouflaged, fired at long distances (more than 1000 meters)

        Marxman- the same shooter, who has undergone special training, has the skills:
        - high-precision shooting at small and medium distances,
        - work on the battlefield in close contact or even as part of (attached for a while) with ground operations units. Ie by itself does not work. It is an organic part of the unit that performs a fairly large amount of work both in shooting and identification and targeting. Weapons of both Rifles and standard assault rifles with special sights, automatic rifles brought to the state of high-precision battle weapons.
        - Not static, moves with the unit
        - Does not apply camouflage on the ground
        - Distances of effective damage to 800 meters

        Sharpschooter - A fighter armed with precision weapons, acting as part of a unit.

    It seems that the technical part of the article, but
    Rebels often use the civilian population as a human shield. This behavior makes it almost impossible for the security forces to respond with fire, as there is a threat to the civilian population and this causes collateral losses.

    It's really brain juice. The author lives in a parallel reality ... or he lives separately with the brain - it is not clear. The "coalition forces" (we read - the US army because they are the only forces capable of combat) deeply do not care about civilians. It is enough to read about another air raid on a wedding or watch videos of them shooting journalists (yes, that video video posted by Bradley Mening)
    Yes, and call PARTISAN rebels somehow strange. If there are occupiers, then these are partisans.

      This is unofficial. And the official position says that they are protecting the civilian population. And in general, this rifle looks like an attempt to conclude a new contract with the US Department of Defense in order to take its place at the trough, called "military budget".

    Some other machines at the dude. This is clearly not AK 74 and AKM, more like clones. And so in the hands of people like the shooter in the video with his constant training in shooting, any weapon will also shoot accurately. Hence the conclusion: you need to shoot a lot and constantly to show such results.

    Squad sniper weapon (four fighters) is not intended for specialized sniper weaponry. One of the main requirements for such weapons is the interchangeability of ammunition and magazines with automatic rifles and light machine guns (М249 Minimi). The rifle has a maximum sighting range of 800m, the optimal one is 600m (with a direct shot range of a 5,56 mm cartridge - 450m).
    A single semi-automatic firing mode is basic, because automatic fire will lead to rapid heating of the barrel and, as a result, to a decrease in accuracy.

    "Multiplication table" for the shooter: using the Mildot-Master counting ruler, you can calculate the firing range and decrease the trajectory
    what is the multiplication table ???? I saw on TV that Rambo shoots three kilometers offhand, and the rest use computers to calculate! you still say that green berets use nl10!

But. podizh you. The concept of SVD turns out to have the right to life when the backside ......... The article smiled.

    It's right. Do you need to combine the qualities of an assault and sniper rifle? Better than the 7,62mm SVU-AS there is nothing here.

    Dear vyunosh, did you play the computer? Nothing so that this squalor has long been gathering dust in the guns and the snipers flinch with horror from the mere memory of this wunderwaffle? of the most serious shoals in the first eyes of the shooter is in the zone of maximum gas pollution and after 3-4 shots it starts to water cleaner than from a gas spray, it is not clear why the introduced author. mode, although even according to AVT-40 it was clear that on the 7,62X54 rifle it is suitable only for the non-cannon-fired burning of cartridges, and maybe there is nothing, but it will only be designed by a "gloomy Izhevsk genius" so that a rifle standing on one often shoots bursts - due to the long terrible thrust, the descent is exceptionally "smooth" can be said to be truly "sniper", ergonomics like an iron, a lot of jambs with "convenience" of placement of controls inherent in all rework bulpups and much more on the little things.

    Cartridges of caliber 5.45 already, in principle, have a good lay trajectory. I understand perfectly that we have a gigantic number of sniper cartridges 7.62x53R and there are barrels in the lubricant under them. But purely theoretically, would the development of an accurate weapon at short medium distances under 5.45 be adequate? There is good flatness, so it can disperse in a longer barrel than the AK-74?

    Long distances in the title are features of the translation ?! The effective sighting range of the MK -12 700 m is like that of the SVD 1200 m only theoretically.
