The Dual Taper Lock system works in conjunction with our proprietary tapered barrel extension and tapered barrel. This provides a "push-pull" relationship ensuring bore centricity of the upper receiver and barrel.
The Blackout Defense Helix Gas Regulating Barrel System integrates an adjustable control knob directly onto the barrel, allowing precise gas flow tuning for suppressed or unsuppressed setups. Built for durability, it features a robust detent system, M42 cobalt steel adjustment rod, and high-temp spring, proven through 1,500 rounds of accelerated full-auto testing with zero failures.
