I have a KAW linear comp on my 16” .458 Socom and it works extremely well, as it was mentioned earlier these muzzle devices don’t reduce recoil or muzzle climb, these brakes are designed to send the muzzle blast & report down range and they do a pretty good job.
I have found that the recoil is just a tad sharper on my .458 Socom compared to my friends build but his rifle is way louder and way more “blasty” than mine.
A have another friend that has a 10.5” 5.56 AR pistol with a KAW linear brake and an SLR-7 adjustable gas block and the gun is actually pleasant while shooting next to him, I have a Surefire Socom brake on my 14.5” AR and a VG6 Epsilon on my 16” AR and both of them are obnoxious when shooting next to them.
