Bear Creek Barrel and Muzzle Device

The Bear Creek barrel is 10.5 inches, chambered in 9mm, and carries a black nitride finish with a 1:10 twist rate. The thread pitch is 1/2x36, which matches the included nitride GI type birdcage flash hider. At 10.5 inches this barrel keeps the overall platform compact while covering the front end 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 ultra-lightweight minimalist freefloat M-Lok handguard is 6061-T6 aluminum in black with a partial top rail, providing M-Lok attachment points along the rail body for accessory mounting. These two components define the exterior structure of the upper assembly on this AR-9 platform.

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. A Mil-Spec AR-15 M4 charging handle is included to complete the upper component set. These two parts 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, recoil spring, end plate, and castle nut are included as part of the rear hardware, with the brace selection remaining with the buyer.
