VG6 Gamma 556 Muzzle Device

Good unit.

Function vs. price- one of the very best I've used.

Thanks for sharing your feedback, T.M. We're glad you're satisfied with your purchase. Cheers!
Excellent Addition to your builds

Well worth putting on your next build or if your looking for no muzzle climb. Product is crafted well and built to last. Son was impressed with price point compared to his more expensive brake. This brake performed as good or actually better than his higher priced brake. Will buy another for my next build.

Thank you for the great review, Eric.We really appreciate you taking the time out to share your experience with us—and we agree, VG6 GAMMA 556 Muzzle Brake is truly great! - AB
Works great, but could use instructions

This hybrid works wonderfully with kickback and muzzle rise! The only difficulties are 1) it doesn't come with instructions (beyond just screwing it on) and 2) it needs to be positioned correctly, but isn't self-explanatory as to how to ensure it's tight once positioned (i.e. no locking nut, etc.)
