With this choice of options offered, finding the right muzzle device for an assault rifle can quickly turn into an almost impossible task. Manufacturers offer literally a sea of muzzle devices, ranging from muzzle flash suppression devices and kickback control to quick-release mufflers, combined mufflers / muzzle brakes and reflective shields.
The information in this article can help, based on the specific operational role of the weapon in question, to make the best decision. The easiest and most logical way to benefit from all this information is to break it down into categories: flame arresters, muzzle brakes, combined muzzle brakes / flame arresters, flame arresters, and finally sound silencers.

In fact, the flame arresters constitute a special group of muzzle devices, the task of which is to eliminate or reduce the muzzle flash coming out of the barrel after the bullet, by scattering gases upwards and sideways so as not to raise dust.
One example of such a device is the XEUMFF FLASH HIDER flame arrester from V.E. Meyers. The 249F device, originally designed to work on ships in low light conditions, regularly wins first place in the US Department of Defense tests and has an excellent reputation among end users. Able to withstand operation in the toughest combat conditions and having a service life of tens of thousands of shots, the 240F FLASH HIDER flame arrester is a proven solution for reducing small arms signatures. According to official estimates by the US Army, 240F excludes 249% of the entire visible muzzle flash, for which he received the highest score during testing. The flame arrester prevents short-term loss of sight of the shooter and distortion of night vision devices, preventing the soldier from losing sight of the target throughout the battle.

Briefly about silencers
Assault rifles, by their nature, are quite noisy systems. The striker’s striker, striking the primer, creates noise, the cyclical nature of the work also creates noise, but a really big bang creates a bullet overcoming the sound barrier and gaseous products of combustion leaving the barrel at supersonic speeds, cutting the surrounding air space. These powder gases are the cause of most of the noise and the whole flash.
The task of the muffler is simple - to keep burning powder gases inside and absorb their energy. Most silencers are hollow cylinders made of metal (usually steel or aluminum) or plastic, containing small chambers within themselves, separated by baffles. Manufacturers use various angles and openings in the design of silencers, resize and resort to other tricks so that the powder gases have the opportunity to expand, cool and calmly flow out of the device.
Just how effective is your typical muffler while reducing the volume of a typical shot? Rifle shots emit a volume of about decibel 160-180. A good silencer removes dB from this 20-40 signature and often makes it “hearing-safe”, as the norm requires. In general, the larger the silencer, the better it will cope with its task.
These muzzle-compensating devices allow reducing the recoil force and throwing up the barrel during firing. They allow you to improve the accuracy of automatic fire and reduce the time of aiming after a single shot. In the production of the second and subsequent shots the muzzle brake helps to keep the target in the optical sight with the increase. Holes, which are an integral part of the design of the brake, working in combination with a set of reflective walls, also contribute to reducing wear of the muffler and increase its life.
Daniel Defense's Muzzle Climb MITIGATOR Gen II muzzle brake redirects gases through calibrated openings, counteracting recoil forces and muzzle bounce. Reduced recoil and bounce leads to faster and more accurate subsequent shots, as well as reduced fatigue. Muzzle device made of aviation stainless steel 17-4, weighs 2,52 ounces (72 grams).
V Seven Weapon Systems recently unveiled a new HELIOS linear melee compensator. According to V Seven, this muzzle device HELIOS, made of titanium brand Grade 5 and different 100% corrosion resistance, due to the redirection of the muzzle wave preserves the hearing and mental health of neighboring shooters. The design in the style of “short-barred Kalashnikov” allows you to send a shock wave and the sound of a shot forward and to the side of the shooter. The company V Seven states that the shooter, firing from a carbine or rifle, equipped with a muzzle brake HELIOS, will receive some reduction in the intensity of the flash bonus. Although they say that the brake is designed for melee weapons, it will work reliably with the barrel of any caliber length up to .338. This device with a diameter of 3,2 cm is suitable for installation on most rails and adds to the weight of the weapon the entire 57 gram. HELIOS comes with 1 / 2x28, 5 / 8x24 thread pitch, as well as in two coatings - titanium and carbon black.

Muzzle brakes / flame arresters
These combined devices provide muzzle flash suppression and reduced recoil, offering a solution to those who operate with a gun with a silencer only a fraction of the time. According to the company, SureFire's WARCOMP flame arresters from the SOCOM family of flame arresters "provide a reduction in muzzle flash of more than 99% compared to a smooth barrel and virtually eliminate the jump in the muzzle of the barrel." They are manufactured with high precision stainless steel followed by the application of a diamond-like carbon coating; the threaded part allows you to attach these devices to most popular rifle models. WARCOMP flame arresters also serve as adapters for mounting the Fast-Attach silences of the SOCOM series.

These devices are designed to direct the shock component of the muzzle wave forward. Due to the direction of the shock wave forward, they reduce the impact force acting on the neighboring shooters and people in the immediate vicinity. These devices also minimize the effects of dust raised when shooting from a prone position. Flame protectors can be screwed directly onto the end of the barrel or work in combination with other muzzle devices already mounted on the weapon.
Gemtech's latest BLAST JACKET accessory is installed on all existing Gemtech Quickmount adapters. BLAST JACKET directs the muzzle to the front, away from other shooters, and prevents the rise of clouds of dust, which, as a rule, rise when lying down. According to a company representative, “we have manufactured a reliable device of pure titanium, so it weighs only 99 grams; high-grade stainless steel spring capable of withstanding a million compressions. It adds to the length of the weapon the entire 6,5, see, this is a great addition to the outfit of any soldier. ”
Delta P Design manufactures a BREVIS silencer line. These mufflers, screwed onto the barrel, are simple and reliable in operation. All BREVIS silencers are robust and affordable.
At SHOT Show 2018, Magpul introduced its new Magpul Suppressor Cover - 5.5in. This is the first such product of the company capable of withstanding extreme temperatures after long lines in automatic and semi-automatic modes and at the same time protect the operator from burns.
Magpul Suppressor Cover - 5.5in is a heat-resistant polymeric sleeve mounted over a cylindrical heat shield made of stainless steel, which is mounted directly on the muffler housing with steel clamps. This allows minimizing heat transfer and keeping the temperature of the outer polymer shell 540 degrees lower than the surface temperature of the muffler due to the passage through it of large volumes of cooling air. Magpul claims that its muffler casing meets the requirements of the Special Operations Command for improper handling of weapons and easily withstands repeated cycles of heating the surface of the casing by more than 700 degrees, which allows the shooter to wear a weapon on the belt after shooting without fear of burns clothes.
This casing, working as an improved heat insulator and signature reduction device, significantly reduces image distortion in the sight, protects the silencer case from damage and reduces the risk of injury or property damage when in contact with a hot silencer.

SAKER ASR is designed for installation on semi-automatic and automatic weapons with a longitudinal sliding gate. In addition, the design of SAKER ASR allows you to maximize the convenience of working with him and to minimize the time to adapt the user
Shooting silencers can be deceptively simple. In fact, most of them are just tubes with partitions, but in the case of assault rifles, not all mufflers are equal in capabilities. Some are really very simple, but now most of them have a modern design, which effectively reduces the acoustic signature of the rifle and eliminates the muzzle flash, but adds a minimum weight to the front of the weapon. Many devices can be mounted on a weapon quickly and easily in the field without any tools. In general, they are a cylinder with a lot of partitions and holes that suppress the sound of a shot due to the direction of expanding gases through the chambers, which absorb energy, cool the gases and smooth out their outflow into the open space outside the muffler. Most of the silencers is a welded cylinder in which partitions are placed, which are fixed by means of welded or screwed plugs. Cylinders are mostly unified in internal and external diameters (thickness). This thickness is determined by the amount of material needed for those areas that are experiencing the greatest load.
The Fast-Attach SureFire SOCOM 2 silencers are among the most advanced silencers in the world with certain enhancements to the original SOCOM series, which includes the SOCOM556-RC and SOCOM762-RC models. On them, the company received contracts after it won in several of the most difficult and tough tests in stories US Command Special Operations Forces. These models have characteristics that are critical for a combat-ready silencer: compact size, minimal weight, a significant reduction in acoustic and dusty signs of visibility (unmasking a cloud of dust), reliable internal partitions, extreme long-term reliability that allows continuous operation, and ) the actual exclusion of the first shot flash, reduced back pressure, reducing the effect of gases on the operator.
In December 2017, the company American Clandestine Equipment unveiled its new silencer SMG9-SC, designed for installation on the Czech submachine gun CZ SCORPION EVO 3 S1 / A1. Model SMG9-SC, manufactured from 7075-T651 aluminum alloy on precision machines, has 12 taper holes and a large internal volume, which allowed to reduce the sound volume on 32,5 dB. According to the company, this design minimizes moving the target mark to less than 2 minutes of angle and completely eliminates the flash at the first shot. SMG9-SC weighs 305 grams, has an overall length of 224 mm and a diameter of 41 mm. The adjustable adapter with the 1 / 2-28 thread, created specifically for the CZ SCORPION submachine gun, used a lock “providing a rigid mount that prevents the silencer from loosening during movement or firing.”
