Ok, so please keep in mind that this comparison was not meant to be scientifically viable in any way. The main purpose was to show the difference in the flash suppression capabilities of each muzzle device (the second half of the video shows this better than the first). It is somewhat difficult to draw any firm conclusions concerning the muzzle rise and impulse reducing capabilities of both muzzle devices, considering that the AR with the XTC had both a longer and heavier profile barrel (16" government profile vs. 14.5" pencil barrel) and was heavier in general (8.1 lbs. vs. 7.5).
Keeping the above considerations in mind, here were my observations:
The BCM Gunfighter definitely had superior flash suppressing capabilities.
The XTC seemed to be more effective at mitigating impulse–again, hard to definitely say given the differences between the two rifles aside from their muzzle devices.
Both seemed to control muzzle rise quite well, with a slight edge to the XTC.
The BCM was noticeably less concussive (something that doesn’t come out well in the video).
Obviously, I’m quite happy with both muzzle devices, as they are both of superior quality and design. However, in an indoor environment, I would probably choose the BCM due to its better flash hiding capability as well as the fact that it’s not quite as concussive.
Also, I thought it would be helpful to provide a picture comparison so you can see the difference in the flash/gas dispersion between the two muzzle devices. Each picture is within .34 seconds of the next.
Both comps serve their purposes in their individual applications. I personally prefer the BCM for indoor CQB with my fellow team mates especially when your doing dynamic entries in real tight spaces. My fellow team mates have also purchased the BCM comps and they love them.
