Features

The MK1 PSD 9.5 inch 300 Blackout AR Pistol from Griffin Armament is a compact, high-performance AR-15 platform built for reliability, smooth operation, and modern tactical use. Chambered in 300 AAC Blackout, this AR pistol is optimized for both subsonic and supersonic ammunition, making it ideal for suppressed shooting while maintaining strong performance in a compact configuration. Designed as a complete system, the MK1 series integrates tuned components to deliver consistent function in both suppressed and unsuppressed setups.

The 9.5 inch barrel is paired with a pistol-length gas system and a suppressor-optimized buffer system, providing smooth cycling and reduced recoil. A lightweight, anti-rotation low-profile M-LOK handguard offers a rigid mounting platform for optics, lights, and accessories while preventing rail movement under stress. Finished in black for durability and a clean tactical appearance, this 300 Blackout AR-15 pistol delivers a versatile combination of compact size, suppressor-ready performance, and modular capability for tactical use, training, and range applications.
