If you want a muzzle device that will make you shine at the range without drawing attention to itself, there’s no reason to look anywhere else, the VG6 GAMMA 300BLK is the 300 Blackout Muzzle brake you need.

The VG6 GAMMA 300BLK doesn’t make much of a splash at first glance. It takes up the same space as a standard A2 flash hider and it will even accommodate many of the accessories supported by the A2 flash hider. If you don’t want to tell anyone about the magic it does, it won’t give you away, but that small package does big things when you pull the trigger.

The VG6 GAMMA is precision machined to perform like no other small brake you’ve seen. The VG6 wizards at Aero Precision used computational fluid dynamics and computer-aided engineering to create a dual chambered muzzle device that not only puts recoil in your rear view but negates muzzle rise too. As a result, you won’t be searching for the target between shots and you can handle your rifle with finesse instead of battling recoil and buck. Shooting goes back to being an art rather than a battle, even with large bores. When you choose a GAMMA for your 300 Blackout Muzzle Brake you can spend your time at the range the way you want to, grinning at the guy next to you who wants to know where you got the dead eye and the steely nerves.

The VG6 GAMMA 300BLK is precision crafted from 17-4ph® Heat Treated Steel and given a satiny BLACKNITRIDE coat that will protect it from the elements and caustic propellants. When you order the VG6 GAMMA, it comes packaged with a crush washer for hassle free installation. Just install it go, no one will ever know your secret if you don’t tell.

    To start out, when I bought this muzzle brake there were no reviews yet so I wasn’t sure what I was getting. On a AAC 300 blackout complete rifle, I went from the factory AAC muzzle flash to this VG6 gamma muzzle brake. To me it was like shooting a 30 caliber bullet and bringing down the recoil to a 556 level. It definitely made a difference. Obviously less recoil = better follow up shots. Very pleased with this muzzle brake. It does exactly what you want it to. Highly recommended!!!
