True Blue Pistol Configuration

This kit ships with a Gauntlet Arms polymer brace designed for pistol operation. The 7.5-inch barrel length combined with the pistol-gas system creates a compact, maneuverable platform. The 1:7 twist rate stabilizes a wide range of 5.56 ammunition weights. The freefloat handguard isolates from the barrel for improved consistency, while M-Lok slots provide modular mounting options throughout the handguard length.

5.56 NATO Pistol-Length Gas System

The pistol-gas system is optimized for shorter barrels and reduced dwell time. Combined with the 3-ounce standard carbine buffer and heavy-duty pistol buffer tube, this configuration manages recoil impulse in a compact form factor. The micro low-profile gas block minimizes profile while maintaining reliable cycling.

Freefloat M-Lok Handguard Design

The ACE-20 Series 7-inch handguard floats independently from the barrel, eliminating contact that can affect shot consistency. M-Lok mounting points run along the handguard for lights, grips, and other accessories. The 6061-T6 aluminum construction keeps weight minimal while maintaining rigidity.

Complete Component Set Included

This kit includes the upper receiver, barrel, handguard, bolt carrier group, charging handle, Gauntlet Arms brace, buffer tube, buffer spring, buffer weight, receiver end plate, and gas block. Lower receiver not included.
