Barrel and Muzzle Device

The 10.5-inch barrel is steel with a black nitride finish and a 1:10 twist rate chambered in 9mm. The barrel thread pitch is 1/2x36, matching the included 9mm Flash Hider A2 birdcage muzzle device. This barrel keeps the overall platform compact and covers the front end of the build from muzzle device to upper receiver.

Upper Receiver and Handguard

The upper receiver is 7075-T6 aluminum with an anodized finish and M4 feed ramps. The 10-inch freefloat M-Lok handguard is 6061-T6 aluminum in black, with M-Lok slots along the body and a quad rail section at the front end for accessory mounting. These two components establish the exterior structure of the upper assembly.

Bolt Carrier Group and Charging Handle

The 9mm nitride bolt carrier group is 8620 alloy steel with a nitride finish, spec-matched to the 9mm AR-9 platform. The Mil-Spec AR-15 M4 charging handle is included to complete the upper component set. Together these cover the upper internal components beyond the barrel and handguard.

SBR Ready Configuration

This kit ships without a brace and is intended for customers selecting their own final rear configuration. The buffer tube, buffer, and recoil spring are included as part of the rear hardware, with the brace selection remaining with the buyer.
