Barrel and Upper Receiver

The 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 barrel steel gas block positioned beneath the handguard. The upper receiver is 7075-T6 aluminum with an anodized finish and M4 feed ramps. 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 and is 9310 alloy steel with a nitride finish. A Mil-Spec M4 charging handle completes the upper component set.

Buffer System and Lower Components

The kit includes a Mil-Spec heavy-duty 6-position aluminum buffer tube, a 3 oz standard carbine buffer, a standard AR-15 carbine recoil spring made in the USA, a Mil-Spec receiver end plate, and a castle nut. 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.

SBR Ready Configuration

This kit ships without a brace, placing brace or stock selection with the buyer. The SBR Ready configuration is intended for customers who have a specific final setup in mind and want to source that component independently. Configuration is setup dependent, and compliance with applicable laws governing stock installation is the responsibility of the buyer.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. Ships without a brace. Do not install a stock unless compliant with applicable laws.
