![]() While a bare muzzle offers no recoil reduction, it has no quirks and recoils in a fairly straight line to the rear. For all videos other than the bare muzzle, the video of the rifle being fired with the specified device will be seen, semi-transparent, on top of the video of the rifle with no muzzle device being fired. ![]() We’ll start with the bare muzzle as a baseline and then move on to the other devices. With that in mind, here’s a chart showing the downward forces caused by each device.įor those interested in the specifics of individual devices, here are the videos, which were shot with a 16″ midlength upper on a registered full auto lower. We don’t always fire from the standing position, and if you’re trying to shoot side prone or underneath the bumper of a car, a device which “combats muzzle rise” will be constantly forcing the muzzle left or right with every shot. The ideal device in terms of muzzle control would keep the muzzle exactly where it was before the shot was fired. Therefore we should use devices that push the muzzle down, right? There is no inherent tendency for the muzzle to rise on its own. In other words, the only reason “muzzle rise” exists is due to the way we position ourselves as we shoot, and we can position ourselves to minimize that, especially with a 5.56 AR-15. Unless, that is, you adjust your stance and hold to limit this effect. However, because there is much more of your body below the point where the stock meets your shoulder, and because that part of your body is eventually connected to the ground, there will be a natural tendency for the muzzle to move upwards. It has to move in some direction, because an external force has acted upon it and it is no longer “at rest.” Because your body is connected to this arm, and the rifle is long and essentially pointed at (in physics terms, not weapon terms) your body, the arm will move mostly to the rear. ![]() They do not inherently cause the muzzle to move up – if the rifle were to be suspended in the air, it would move straight back.īut it’s not suspended in the air, it’s connected to your body. The gases exiting the muzzle do so in a very uniform manner, with essentially no variation from side to side and top to bottom. In scientific terms, the rifle is an arm with forces being placed upon it at the very end – the muzzle. If we think of limiting rearward forces as recoil reduction, then limiting upward forces must be called “combating muzzle rise,” right? Wrong.Ĭonsider yourself shooting a rifle with a bare muzzle from the standing position. ![]() SilencerCo’s massive Specwar triple port brake/silencer mount was by far the most effective device at recoil reduction, for example, but it was also loud and created a distinctive muzzle flash. Not surprisingly, the most effective muzzle devices in the test were also at the loud and bright end of the spectrum in the previous tests. During a four month period, over 1500 rounds were fired to verify g-force data from the accelerometers. Using high speed video (courtesy of SilencerCo) and multiple accelerometers, I will be able to show visually as well as mathematically how effective each device in the test is at recoil reduction. Late last year I published parts one and two of a muzzle device comparison the third part was essentially complete at that time, but I decided to hold off on publishing it until I could verify some of my data.
