A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.
The CPW weighs only 1.5 kg empty/dry (2 kg with a fully loaded 30-round 9 mm magazine) and uses a unique bolt lever cam recoil mitigation system to control recoil and muzzle rise to increase target hits. Full-auto cyclic rate of fire is a relatively high 900 to 1100 rpm. [35]
Illustration of forces in muzzle rise. Projectile and propellant gases act on barrel along barrel centerline A. Forces are resisted by shooter contact with gun at grips and stock B. Height difference between barrel centerline and average point of contact is height C. Forces A and B operating over moment arm / height C create torque or moment D, which rotates the firearm's muzzle up as ...
The 3DX is the first 3D printed muzzle brake available for commercial sale with muzzle control on semi-automatic and fully automatic. It uses 100% Inconel superalloy construction and Ionbond Diamondblack coating. The threading is 1/2×28RH for 5.56×45mm NATO, .223 Remington, and smaller calibers. The brake comes with installation instructions ...
The AMT Auto Mag V was designed to fire the .50 Action Express cartridge, and its barrel had compensator ports to help keep muzzle rise to tolerable levels. It was made primarily of cast stainless steel , and was designed to accept a 5-round magazine .
For instance, muzzle brakes primarily works by diverting some of the gas ejecta towards the sides, increasing the lateral blast intensity (hence louder to the sides) but reducing the thrust from the forward-projection (thus less recoil). Similarly, recoil compensators divert the gas ejecta mostly upwards to counteract the muzzle rise.
NERO 556 Muzzle brake [80] [81] 2018 [80] Muzzle device: AR-15 rifle muzzle brake [68] DMLS [81] w/ Inconel [82] Walker Defense Research [83] [81].223 Rem/ 5.56x45 "The idea was to create a muzzle brake with no equal; one that turns the recoil of an AR-15 into a slight push with zero muzzle rise." [80]
The weight of the silencer itself and the leverage of its mounting location (at the far front end of the barrel) will also help counter muzzle rise. Because the internal baffles will slow and cool the released gas and contain gunpowder that is still burning upon exit from the muzzle, silencers also reduce or even eliminate the muzzle flash.
