Saxhorn Barrel and Upper Receiver

The Saxhorn barrel runs 7.5 inches in .300 Blackout with a 1-in-8 twist rate, H-Bar profile, and 4150 Chrome Moly Vanadium construction finished in phosphate. A pistol-length gas system pairs with a .750 O.D. micro low-profile gas block positioned beneath the handguard. The upper receiver is 7075-T6 aluminum with an anodized finish. Thread pitch is 5-in-8x24, and the kit includes a GI Birdcage flash hider sized for the .308 bore diameter at that thread pitch.

Handguard

The freefloat M-Lok handguard is 6061-T6 aluminum with a purple anodized finish, carrying the Lightshow build aesthetic across the upper assembly. The freefloat profile provides a clean forend with M-Lok interface for accessory placement along the rail. The .750 O.D. micro low-profile gas block sits beneath the handguard, keeping the exterior profile clean along the forend.

Bolt Carrier Group and Charging Handle

The included bolt carrier group covers the 5.56, .223, .300, and .350 platform family. The bolt head is 9310 alloy steel and the body is 8620 alloy steel, both finished in nitride. A Mil-Spec M4 charging handle completes the upper component set.

Magpul BTR Pistol Brace

The kit includes the Magpul BTR pistol brace in black. The BTR brace pairs with the included Mil-Spec heavy-duty 6-position buffer tube and provides the rear interface for this pistol configuration.

Buffer System and Lower Components

The kit includes a Mil-Spec heavy-duty 6-position aluminum buffer tube, a 3 oz buffer, a standard AR-15 carbine recoil spring, a Mil-Spec receiver end plate, and a steel castle nut with phosphate finish. A lower parts kit covers the internal lower receiver components required for lower completion. These components cover the full lower completion hardware outside the serialized receiver itself.

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