Davidson Defense Mil-Spec AR-15 6-Position Carbine FDE Stock Kit with 9mm Carbine Buffer

This is a complete stock kit for AR-15 and M16 platform builds, centered on an M4 style adjustable carbine buttstock in flat dark earth reinforced polymer with a 6-position adjustable length of pull and Mil-Spec carbine receiver extension compatibility. The kit includes a Mil-Spec heavy-duty AR-15 6-position carbine buffer tube, an AR-15 9mm carbine buffer, a standard AR-15 carbine recoil spring made in the USA, a US Tactical AR-15 and M16 Mil-Spec receiver end plate, and a Mil-Spec AR-15 carbine castle nut, covering the full rear hardware group in one package.

Stock and Buffer System

The M4 style adjustable carbine buttstock in flat dark earth reinforced polymer fits directly onto Mil-Spec carbine receiver extensions and offers a 6-position adjustable length of pull locked in place by a spring-loaded adjustment lever. The low-profile and lightweight design keeps the rear end trim without adding unnecessary bulk to the build. The textured non-slip buttplate provides a consistent and secure shoulder contact surface, and the integrated sling loop covers sling attachment at the rear end without additional hardware. The Mil-Spec heavy-duty 6-position carbine buffer tube pairs directly with the stock and accepts the AR-15 9mm carbine buffer and standard AR-15 carbine recoil spring made in the USA as part of the complete rear hardware group. The 9mm carbine buffer is the correct buffer choice for AR-9 and pistol caliber carbine platforms on the Mil-Spec carbine buffer tube, addressing the heavier buffer weight requirement of blowback-operated 9mm builds. The US Tactical AR-15 and M16 Mil-Spec receiver end plate and Mil-Spec AR-15 carbine castle nut complete the rear hardware set, locking the buffer tube down at the lower receiver and giving the builder everything needed from the lower receiver rearward in one kit.
