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 ...
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.
Comparison of milliradian (mil) and minute of arc (moa).. Since adjusting the point of impact to match the point of aim is relatively simple with any type of adjustable sights, the primary goal of accurizing is to increase the precision of the firearm, which is generally measured by looking at the dispersion of a number of shots fired at the same point of aim.
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.
While the terms "muzzle brake" and "recoil compensator" are often used interchangeably, if you search on "muzzle brake" you'll find a greater number of symmetric dispersion devices for rifles and artillery, and if you search for "recoil compensator" you'll find more devices designed to address muzzle rise in handguns, SMGs, shotguns, and carbines.
A muzzle reference system (MRS) is a device used on most modern tank guns and some artillery systems that measures the bending of the barrel due to heat, gravity and other issues. It normally consists of a laser device and detector mounted at the breach end of the gun, often co-located with other optics like the gunner's sight, and a mirror at ...
A flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons. Its primary intent is to reduce the chances ...
[citation needed] The process duplicates the sound waves generated by the muzzle blast and then uses them to create an anti-phase auditory signal. Currently, this is a muzzle attached device and is only being tested to cancel out the gunshot sound of the firearm. The devices tested incorporate multiple microphones, speakers, and an auditory ...
