Barrel and Upper Receiver

The barrel runs 4.5 inches in 9mm with a 1-in-10 twist rate, medium profile, and 4150 Chrome Moly Vanadium construction with a nitride finish. The upper receiver is 7075-T6 aluminum with an anodized finish and M4 feed ramps. Thread pitch is 1-in-2x36, and the kit includes a 9mm A2 Birdcage flash hider in manganese phosphate finish.

Handguard

The 4-inch Honeycomb freefloat M-Lok handguard is aircraft-grade aluminum with a grey 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.

Bolt Carrier Group and Charging Handle

The included 9mm bolt carrier group is 8620 alloy steel with a nitride finish and is compatible with Glock and Colt magazines. 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 anodized aluminum buffer tube, a 9mm carbine buffer, a standard recoil spring, a 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.
