Self-loading rifle Kel-tec RFB
Who served in the army, he knows how difficult it is for a person to shoot - left-handed with an AK-74 submachine gun or an RPG-7B grenade launcher. A similar situation arises with the SVD sniper rifle, which was in service in the 80-ies of the XX century. Some opponents may object to me that one can be taught everything. I agree. You can teach. But to retrain when conditioned and unconditioned reflexes come into play, which are “photographed” in our brain and tightly connected to our consciousness — it is impossible. You can, of course, ideally achieve 80 percent efficiency. But closer to the ideal will not come. And the sniper is a very responsible person, and the word "may" does not fit him.
The task of creating a special weapons For those with an active left hand, Kel-tec CNC Indusries chief designer, George Kelgren, successfully decided to create an outstanding model of small arms - the self-loading rifle Kel-tec RFB.
Creating SUB-16
Being a Swede by descent, D. Kellgren moved to work in the North American States, where he was invited by the employer. His first job at this company was the release of the SUB-16 compact carbine in the "bullpapp" version under the "NATO" cartridge of the 5,56 caliber mm. A feature of this type of weaponry, which seemed to be a “counter-attacker weapon”, was the frontal extraction of fired ammunition, with the help of a special window located in the rifle's shank above the barrel part. But the US Congress intervened, and after ratifying the Assault Weapon Act in 1994, the demand for the product plummeted, and the program for the production of these weapons was closed. However, in 2003 a goal, Kel-tec received an order for the design and manufacture of prototypes of a sniper self-loading rifle for a special cartridge of the same caliber, which must combine two incompatible things — a long barrel part and a bullpapp /
Create Kel-tec RFB
In the 2005 year, a similar order is received for a rifle chambered for 7.62 x 51 NATO, the project was named SRT-8, but the following year it was renamed the RFB project. This abbreviation literally means - a rifle with the ejection of sleeves forward, bullpapp. Product development was simultaneously conducted in three versions, which differed in the length of the barrel. Their length was 18, 24 and 32 inches and the prototypes of the rifle were called, respectively, sniper, hunting and combat rifle. The names of the modifications clearly defined the purpose of each type of weapon. But at the final stage the names were replaced with “target”, “sport” and “carbine”, respectively, the length of the barrel. In such names, this type of weapon was presented at the world exhibition of weapons ShotShow, held at that time in America, and from 2008, the mass production of this weapon began. Advertising for the release of these weapons was appropriate.
Features rifle Kel-tec RFB
The constructive advantages of the product include small size and weight, which are surprisingly combined with the length of the barrel part, because of which ballistics became better and the firing range reached great results. The linear dimensions of the rifle are smaller because of the layout used not only for parts and mechanisms, but also for automation. When carrying out bullet-style small arms, there is one serious drawback: the spent cartridges are extracted near the person’s face, but this gap is filled with an original design solution — the sleeve is ejected forward after the shot, through a special hole above the barrel. part inside the forearm. Such variants of liner extraction exist in FN F2000 (Belgium) machines of 5.56 mm caliber and A-91M made in Russia.
Action mechanisms rifle
In the Kel-tec RFB self-loading rifle, automation was applied using firing gases when firing, with a small stroke of a gas piston and a manual gas regulator. The gas piston, located in the barrel block, transmits the force to the elongated frame of the bolt mechanism, which is made in a U-shaped section and covers the barrel of the rifle from the top and side parts. The U-shaped channel of the mechanism for removal of sleeves located above it is in the same position of capture. In the aft under the shutter frame is directly shutter itself. The barrel bore is locked by skewing the rear part of the bolt mechanism down, while the bolt itself directly engages with the sides of the stem of the barrel. On the sides of the gate, two extractor hooks are made structurally, swinging vertically. During the forward movement of the bolt, special projections in the trunk box release the extractors that hold the ejected cartridge and push the sleeve into the channel for the sleeve. At the final stage of the movement of the bolt-eaters, the ejectors descend to a lower level and cling to the flange of the cartridge, which is directed by the bolt to the receiver. The special spring does not allow sleeves that are already in the sleeve channel to fall into the trunk box. Extraction of the sleeves outside the weapon occurs under the force of ejection of subsequent sleeves or under the action of gravity if the weapon is lowered into the lower position. To get into the sleeve duct is possible only during incomplete disassembly of the product with the shutter mechanism removed.

Despite the fact that this rifle is convenient for shooting arrows - left-handers, the shooter with the usual, right-handed stop can also adapt to shooting from this rifle. Perhaps this is the added convenience of weapons in the configuration "bullpapp"
