The Davidson Defense Lightshow Anodized Grey Upper Build Kit is a .223 Wylde AR-15 pistol upper configuration built around a Spriggan 7.5-inch M4 profile barrel with a 1-in-7 twist rate and a pistol-length gas system. The kit includes an AR-15 upper receiver, 7-inch Guntec Airlite Series Honeycomb M-LOK handguard, and AR-15 GI bird cage flash hider. BCG and charging handle are not included.
The Spriggan 7.5-inch M4 profile barrel is made from 4150 Chrome Moly Vanadium steel with a phosphate finish and a 1-in-7 twist rate. The barrel is threaded at 1-in-2x28, matching the included AR-15 GI bird cage flash hider, and uses a pistol-length gas system. The AR-15 upper receiver features M4 feed ramps and is constructed from 7075 T6 aluminum with an anodized finish.
The 7-inch Guntec Airlite Series Honeycomb M-LOK handguard is constructed from 6061-T6 aluminum with a Type III hard coat anodized grey finish that defines the Lightshow aesthetic across this upper build kit. The handguard features M-LOK interface slots along its exterior for accessory attachment. At 7 inches, the handguard does not extend past the 7.5-inch barrel, leaving the muzzle end of the barrel exposed beyond the handguard profile.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. BCG and charging handle are not included.
