Griffin Armament 1 2x28 9mm Range Adapter

The EZ-LOK™ Barrel Adapter is part of Griffin Armament’s patent-pending universal quick-detach piston system, designed to simplify suppressor mounting while improving security and reliability. This adapter replaces traditional direct-thread mounting methods with a taper-locking interface that minimizes loosening during firing and helps prevent common issues like baffle or end cap strikes.

Built for ease of use, the EZ-LOK™ system allows fast, consistent attachment with a single mounting orientation, making it accessible for users of all experience levels. Precision machining ensures proper alignment, reduced point-of-impact shift, and compatibility across multiple firearms and suppressor platforms when paired with EZ-LOK™ pistons.
