Re: Griffin Armament Muzzle Device Promotional Video
The Brake reduces recoil. Recoil is the force that when directed into a shooter's anatomical position, creates muzzle rise and that has a lot to do with the body contacting surface of the stock being generally below the bore line. By reducing recoil by approximately 60%, the brake is able to reduce muzzle rise to a force that is then controllable using a thumb over grip and good body position whereas the A2 does zero recoil reduction and leaves the shooter with too much rise to effectively control without a lot of training and very tuned, gross muscle input to the weapon.
The M4SD Comp on the other hand reduces recoil by about 42%, and establishes more or less neutral muzzle control by a calculated porting configuration that redirects gas to effectively kill muzzle rise.
The Flash Comp we found to be about 55% effective as a recoil reducer, because the closing of the ports in front increases pressure out of the ports almost like a muzzle brake. We didn't sound test the flash comp like we did the M4SD comp but perceived side concussion is still noticeably less than a muzzle brake, and probably more like a battle comp which has larger venting ports. We actually decided to make a very slight revision to the porting configuration of the flash comp resulting in a second generation comp with the top row of ports closed that will begin hitting the market in a few weeks.
The flash comp is a fairly effective flash suppressor on barrels 14.5" or longer, and creates about the same amount of flash as an A2 flash suppressor. On the shorter guns, driving pressure through the ports begins to cause flash to get more aggressive. We don't have a current plan to offer a specifically tuned version for more acceptable night flash performance on shorter 10.5"-12.5" barrels, but that may be something we offer in the future. As the majority of the civilian market is 16" or longer, the flash comps flash performance was designed with that barrel length in mind.
