Kingswake 11.5-inch 5.56 NATO AR-15 Upper Build Kit

The Kingswake is built around an 11.5-inch 5.56 NATO barrel with an M4 profile, paired with a 7000 Series optimized AR-15 upper receiver. It pairs a 12-inch Air Lite Series honeycomb free-floating handguard with a Walker Steel Flash Can at the muzzle, running on a carbine-length gas system.

Barrel and Gas System

The barrel runs 11.5 inches long, chambered in 5.56 NATO and finished in phosphate with an M4 profile. It carries a 1:7 twist rate, well suited to stabilizing heavier 5.56 bullet weights, along with a 1/2x28 muzzle thread. Gas cycles back to the action through a carbine-length system, running a stainless steel carbine-length gas tube and a micro low-profile steel gas block sized to a .750-inch journal.

Upper Receiver and Handguard

The upper receiver is a 7000 Series optimized AR-15 unit finished in Type III black anodizing, with a dust cover pin feature and a standard .223/5.56 ejection port door. Over the barrel sits a 12-inch Air Lite Series honeycomb handguard, free-floated and finished in black, using an M-LOK attachment system along its length. A monolithic Picatinny top rail runs along the top, giving the buyer a single continuous mounting surface.

Muzzle Device

Capping the muzzle is a Walker Steel Flash Can finished in black oxide. It threads onto the barrel's 1/2x28 pattern and is secured with the included 1/2-inch black crush washer.
