Needle Barrel and Muzzle Device

The Needle barrel is 10.5 inches, chambered in 5.56 NATO, and constructed from stainless steel with an M4 contour profile. The twist rate is 1:7 and the thread pitch is 1/2x28, which matches the included USA-made Crown muzzle brake in nitride finish. A crush washer, a micro low-profile gas block at 0.750 diameter, and a carbine-length stainless steel gas tube cover the front end gas configuration on this carbine-length platform.

Upper Receiver and ACE-20 Handguard

The upper receiver is 7075-T6 aluminum with a black anodized finish, M4 feed ramps, an AR-15 ejection port door assembly, and a forward assist assembly. The 10-inch ACE-20 Series freefloat M-LOK handguard features a full-length top Picatinny rail and M-LOK attachment slots along the body in a lightweight profile. These two components define the exterior structure of the upper assembly on this AR-15 platform.

Bolt Carrier Group and Charging Handle

The complete AR-15 bolt carrier group is compatible with 5.56 NATO, .223 Remington, .300 Blackout, and .350 Legend, and is made in the USA. A Mil-Spec AR-15 M4 charging handle is included to complete the upper component set.

The complete Mil-Spec AR-15 lower parts kit covers the internal lower receiver components. The buffer system includes a Mil-Spec heavy-duty 6-position buffer tube, a standard 3 oz carbine buffer, a standard AR-15 carbine recoil spring, an AR-15 M16 Mil-Spec receiver end plate, and an AR-15 carbine castle nut. The Magpul BTR pistol brace in black pairs with the included Mil-Spec 6-position buffer tube and rounds out the kit, providing a rear interface for the pistol platform.
