Barrel and Upper Receiver

The 5-inch slim profile barrel is 4150 CrMoV steel with a phosphate finish and a 1:10 twist rate. The muzzle is threaded at 1-in-2x36 and pairs with the included 9mm A2 birdcage flash hider in manganese phosphate finish. The upper receiver is 7075-T6 aluminum with M4 feed ramps and an anodized finish, serving as the core front end structure for the AR-9 build. M4 feed ramps support reliable cartridge feeding from the magazine into the chamber. The AR-9 platform operates via direct blowback.

Handguard

The 4-inch freefloat M-Lok handguard is 6061-T6 aluminum with a Type II hard coat anodized purple finish, keeping the forend lightweight and compact. The M-Lok slots provide attachment points for lights, grips, and other accessories. The handguard length is shorter than the 5-inch barrel, and the muzzle device extends beyond the handguard to provide the necessary clearance.

Bolt Carrier Group and Charging Handle

The included 9mm bolt carrier group is built from 8620 alloy steel with a nitride finish. This BCG is the correct unit for AR-9 direct blowback configurations. The AR-15 M4 charging handle completes the upper component set.

SBR Ready Configuration

This kit ships without a brace and is intended for builders selecting their own final rear end configuration. The mil-spec heavy-duty 6-position buffer tube, 5.5 oz 9mm carbine buffer, carbine recoil spring made in the USA, mil-spec receiver end plate, and lower parts kit are all included to support the lower completion build. The SBR Ready designation means the brace selection is left to the builder, allowing for a custom setup based on individual configuration requirements.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. Ships without a brace. Do not install a stock unless compliant with applicable laws.
