LANTAC Dragon 223/556 1/2-28 Thread SilencerCo ASR Quick Mount Muzzle Brake (DGN556B-ASR)

I'll never get a chance to test it with a full auto, but it works amazingly with my AR. Mounted a suppressor on it and it's just perfect: quiet and not punching

I wouldn't call it a false advertisement, but naturally, one muzzle break doesn't negate all the recoil. It does reduce muzzle rise and length of recoil while making it less tangible, so it's still viable, just don't expect miracles from it

I asked customer service and this is not considered a flash hider so Californians can order it safely. It does reduce the recoil and muzzle rise noticeably, just make sure to doublecheck caliber compatibility as it fits only 5.56 and .223
