If you’ve fired a short barrel or pistol AK47 or AR15 then you know how much of a concussion and fireball they produce. A popular brake for SBR and pistol AKs is the Krinkov style brakes, seen here. They’re a multi-piece muzzle device that helps redirect the muzzle blast forward and away from the shooter. Well now they’re available for the AR15s.
You can find them pretty cheap too, they go for just $25 shipped on Amazon.
