I have an AR-Stoner Linear Muzzle Brake (more accurately- a flash/sound forwarder) on a 300 BLK, but it's on a 16" barrel. I cannot feel any increase in recoil over the A2 Birdcage that was there previously. I did a fair amount of research on linear compensators/brakes/flash/sound forwarders online before purchasing one, and I can confirm that my experience with it matches the results that others have reported- if there's any increase in recoil it's too small to physically measure.
