Ultra-Compact 9mm Pistol Configuration

The 5-inch barrel length creates an extremely compact overall footprint while maintaining functional 9mm performance at close range. This ultra-short configuration maximizes maneuverability in confined spaces and provides a unique platform for specialized applications.

Direct Blowback Operation

The direct blowback system eliminates gas system components for simplified, reliable operation with 9mm ammunition. This straightforward design reduces potential points of failure while ensuring consistent cycling across various 9mm loads.

8620 Alloy Steel Bolt Carrier Group

The 9mm nitride bolt carrier group crafted from 8620 alloy steel provides the strength and reliability needed for blowback operation. The nitride finish ensures durability and reduced friction for consistent cycling across extended shooting sessions.

Gauntlet Arms Polymer Stabilizing Brace

The Gauntlet Arms Polymer Stabilizing Brace provides exceptional support and enhanced control while maintaining a low overall weight. This lightweight brace delivers improved shooting dynamics without adding excessive bulk to the ultra-compact pistol platform.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify compatibility of all components before assembly. Designed for pistol-caliber builds—confirm 9mm compatibility with your lower receiver and magazine system. Extremely short barrel length may affect ballistics and noise levels.
