The Warden Duty is a 5.56 NATO AR-15 Upper Build Kit built around a 16-inch carbine-length gas platform. The kit centers on a 16-inch medium profile barrel in 4150 CrMoV steel with a nitride finish, 1:7 twist rate, and 1/2x28 thread pitch, paired with a GI A2 birdcage flash hider and a black 1/2-inch crush washer. A 0.750 gas block and a carbine-length stainless steel gas tube are included on the front end. The upper receiver is a USA-made 6061 slick side billet design in 6061-T6 aluminum with a Type III Class 2 hardcoat anodized finish and an anti-rotation cutout, paired with a 15-inch freefloat Keymod handguard in aluminum. BCG and charging handle are not included.
The 16-inch medium profile barrel is chambered in 5.56 NATO and constructed from 4150 CrMoV steel with a nitride finish. The twist rate is 1:7 and the thread pitch is 1/2x28, which matches the included GI A2 birdcage flash hider. A black 1/2-inch crush washer and a 0.750 gas block paired with a carbine-length stainless steel gas tube cover the front end gas configuration on this carbine-length platform.
The USA-made 6061 slick side billet upper receiver is 6061-T6 aluminum with a Type III Class 2 hardcoat anodized finish and an anti-rotation cutout. The slick side design removes the forward assist housing from the upper receiver body for a clean exterior profile. The 15-inch freefloat Keymod handguard is aluminum with Keymod attachment points along the body for accessory mounting. These two components define the exterior structure of the upper assembly on this AR-15 platform.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. BCG and charging handle are not included.
