Luth-AR BS-M4KM M4 Buttstock w/ Rear Sling Swivel - Mil-Spec .223 Kit - Black

The Luth-AR BS-M4KM is an M4-pattern buttstock kit for the AR-15 / M4 platform, finished in black and styled after the classic military "waffle" stock. The package pairs the buttstock - complete with an integrated rear sling swivel - with a full Mil-Spec .223 buffer assembly, giving builders a complete drop-in package to refresh or build out a carbine.

The buttstock replicates the familiar ribbed "waffle" pattern on the rear face for positive shoulder purchase and grip texture, and incorporates a built-in sling swivel mount that accepts any standard push-button quick-detach swivel. The rear of the stock is shaped to mate with a Mil-Spec pattern carbine receiver extension / buffer tube. The included Mil-Spec .223 kit supplies a standard carbine buffer tube, a .223 / 5.56 carbine buffer, and a carbine buffer spring - all sized for AR-15 / M16 carbines chambered in .223 Remington / 5.56x45mm NATO.

Designed as a direct-fit component for any standard AR-15 / M4 lower running a Mil-Spec carbine buffer tube, the BS-M4KM is a practical upgrade or replacement for duty, training, and general-purpose carbines. Whether refreshing a worn-out factory M4 stock or assembling a new carbine from the receiver up, this Luth-AR kit delivers the classic M4 waffle profile, sling-ready hardware, and the buffer components needed to get the rifle running.
