The Web Slinger 16-inch Carbine-Gas 1:7 5.56 NATO AR-15 Custom Handguard Rifle Upper Build Kit from Davidson Defense is an upper build kit for the AR-15 platform chambered in 5.56 NATO. The kit includes a 16-inch medium-profile barrel, a Unique-ARs 15-inch Web freefloat handguard, a 7075-T6 anodized upper receiver with M4 feed ramps, a micro low-profile gas block, and a GI birdcage flash hider. BCG and charging handle are not included.
The 16-inch barrel is chambered in 5.56 NATO and constructed from 4150 Chrome Moly Vanadium steel with a medium profile and a 1:7 twist rate. The nitride finish covers the full barrel surface for corrosion and wear resistance. The muzzle is threaded 1/2x28 and includes a GI birdcage flash hider with a manganese phosphate finish. The carbine-length gas system pairs with a micro low-profile gas block at .750 O.D., a separate component positioned beneath the handguard on the barrel.
The upper receiver is machined from 7075-T6 aluminum with an anodized finish and M4 feed ramp compatibility. The Unique-ARs 15-inch Web freefloat handguard provides accessory mounting options along its length without contact with the barrel or gas system components.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. BCG and charging handle are not included.
