Davidson Defense Ronin Competition 16-inch .22 LR AR-15 Freefloat M-Lok Handguard Rifle Full Build Kit

Ronin Competition 16-inch .22 LR AR-15 Full Build Kit

The Ronin Competition is a Full Build Kit built around a 16-inch dedicated .22 LR barrel with a pencil profile, paired with a 7000 Series optimized AR-15 upper receiver finished in Type III black anodizing. It pairs a 15-inch ACE Series free-float M-LOK handguard with an A2 GI-style birdcage flash hider at the muzzle. It operates on a direct blowback system rather than a gas-driven cycle. A dedicated .22 LR bolt group, Mil-Spec charging handle, complete Lower Parts Kit, carbine buffer-system components, and a Special Operations adjustable collapsible stock round out the rest of the rifle. The lower receiver is not included, leaving the buyer to select and supply that component separately.

Barrel and Muzzle Device

The barrel runs 16 inches long, built specifically for .22 LR in a pencil profile rather than a heavier contour. It carries a 1:16 twist rate and a 1/2x28 muzzle thread, cycling on a direct blowback system. At the muzzle sits an A2 GI-style birdcage flash hider, threaded to match the barrel's 1/2x28 pattern and secured with the included 1/2-inch black crush washer.

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 provision. The ejection port carries a standard .223/5.56 door with its rod and spring installed. Over the barrel sits a 15-inch ACE Series free-float handguard finished in black, using an M-LOK attachment system with a full-length Picatinny rail running along its top.

Bolt Group and Charging Handle

The bolt group is a dedicated .22 LR unit machined from stainless steel, built specifically for this rimfire chambering rather than shared with centerfire calibers. A Mil-Spec AR-15 M4 charging handle rounds out the upper's operating components.

Lower Parts Kit and Buffer System

A complete Mil-Spec AR-15 Lower Parts Kit covers the fire-control and lower-control internals needed once a lower receiver is on hand. Behind it sits a Mil-Spec heavy-duty six-position buffer tube, holding a standard AR-15 carbine buffer weighing 3 ounces and a standard USA-made recoil spring. An AR-15 carbine castle nut and Mil-Spec AR-15/M16 receiver end plate secure the buffer tube assembly to the lower.

Stock

Capping off the rifle is a Special Operations AR-15 stock, an adjustable collapsible design finished in black. It slides onto the six-position buffer tube included with this kit, giving the shooter adjustable length-of-pull for the final piece of the build.
