Barrel and Upper Receiver

The ELD Performance 4.5-inch medium profile barrel is 4150 Chrome Moly Vanadium steel with a nitride finish and a 1:10 twist rate. The muzzle is threaded at 1-in-2x36 and pairs with the included Recoil Technologies 9mm A2 birdcage flash hider in manganese phosphate finish. The upper receiver is 7075-T6 aluminum with an anodized finish, serving as the core front end structure for the AR-9 build. The AR-9 platform operates via blowback.

Handguard

The Guntec 4-inch honeycomb freefloat M-Lok handguard is 6061-T6 aluminum with a Type II hard coat anodized purple finish, keeping the forend lightweight and compact. The honeycomb pattern reduces weight across the handguard body while the M-Lok slots provide attachment points for lights, grips, and other accessories. The handguard length is shorter than the 4.5-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 blowback-operated configurations. The AR-15 M4 charging handle completes the upper component set.

Magpul BTR Brace and Buffer System

The Magpul BTR pistol brace in black pairs with the included mil-spec heavy-duty 6-position buffer tube. The 5.5 oz 9mm carbine buffer, carbine recoil spring, mil-spec receiver end plate, phosphate-finished castle nut, and complete mil-spec AR-15 lower parts kit cover the core lower completion components outside the serialized lower receiver.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
