High-Performance Muzzle Brake For Eliminating Recoil On 300BLK Calibers

The VG6 GAMMA 300BLK is a high-performance muzzle brake for eliminating recoil. It was designed using state of the art engineering techniques, utilizing CFD (Computational Fluid Dynamics) and CAE (Computer-Aided Engineering). This product is 100% CNC machined for optimal performance.

Tuned For Versatility

The VG6 GAMMA 300BLK is a muzzle brake and compensator hybrid. It virtually eliminates recoil and minimizes muzzle movement. The unique combination of both braking and compensating features inspire shooter confidence and allows the shooter to make very fast follow up shots.

The VG6 GAMMA 300BLK has been tuned for versatility as well. The brake has been optimized for 10.5″ to 18.5″ barrel lengths, but ultra-shorty SBRs and AR-Pistols with shorter barrels and full-sized 20″ rifles will benefit greatly from the muzzle brake as well.

Came for the looks, stayed for the functionality

With my AR15 upgraded end-to-end, I only had my muzzle left to consider. I had heard of the benefits which came with muzzle brakes and figured why not upgrade from my mil spec. I chose the VG6 Gamma 300BLK Muzzle Brake after reading favorable reviews and well, it just looks cool.

Once installed by my gunsmith, the rifle looked more than complete with this on there, the muzzle brake made it all the more capable. Marked reduction in recoil, muzzle rise, and again, good looks aplenty. Would definitely recommend to any AR owner looking for that extra edge at the range,

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Awesome addition

This is an extremely sharp looking muzzle brake. Functionality is spot on. Still going to feel everything, just a little more reserved. And follow up shots are quicker with this. Beats your standard bird cage. Great investment for an upgrade.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!
