VG6 Precision Gamma 300 BLK Muzzle Brake 7.62mm 5/8"-24 Thread Stainless Steel

The VG6 Precision Gamma 300 BLK muzzle brake is built for shooters running .300 Blackout builds who want serious recoil control and the ability to stay on target for fast follow-up shots. Engineered with CFD and CAE modeling, then CNC machined from 17-4ph stainless steel, this brake-compensator hybrid tackles the unique ballistics of subsonic and supersonic .300 BLK loads across the full spectrum of barrel lengths—from short SBRs and pistols to full-sized 20" rifles. The hardened stainless construction and Blacknitride finish hold up to the harsh environment of a suppressor-ready setup, and the recoil reduction means less fight with the gun and more time making accurate shots.

What sets the Gamma 300 BLK apart is its tuning for versatility. VG6 engineered this brake with a focus on 10.5" to 18.5" barrels, the sweet spot for most .300 BLK builds, but the design performs well across shorter and longer platforms too. If you're building a short-range tack driver, a backyard plinker, or a hunting rifle, the Gamma 300 BLK handles the job without the bulk or gas blowback of heavier brakes.

At under 2 ounces, the brake keeps your front end light, and the 5/8"-24 thread is the standard for 7.62mm platforms. The stainless steel construction resists corrosion and the Blacknitride satin finish blends form and durability. Whether you're running suppressed for hearing safety or unsuppressed for flat performance, the Gamma 300 BLK earns its place on a serious .300 Blackout rifle.

Frequently Asked Questions

Will this muzzle brake work on my .300 Blackout pistol or SBR?

Yes. The Gamma 300 BLK was designed with versatility in mind. While VG6 optimized it for 10.5" to 18.5" barrels, the brake performs well on shorter AR pistols and SBRs, as well as longer rifle-length builds.

What thread pattern do I need for a .300 Blackout rifle?

The VG6 Gamma 300 BLK uses a 5/8"-24 RH (right-hand) thread, which is the standard for 7.62mm platforms including .300 Blackout.

Can I use this brake suppressed?

Yes. The stainless steel construction and Blacknitride finish are built to handle suppressor use without degradation. Many shooters pair the Gamma 300 BLK with suppressors for hearing-safe .300 BLK shooting.

What's the weight and how does it affect barrel balance?

The Gamma 300 BLK weighs 1.92 oz, keeping your front end light and minimizing impact on barrel harmonics and handling.
