Luth-AR BS-A1K A1 Buttstock Kit .223 Black

The Luth-AR BS-A1K is a complete A1-style fixed buttstock kit designed for the AR-15 / M16 platform in .223 Remington / 5.56 NATO. This kit brings the classic, fixed-length A1 stock profile to your build, giving retro enthusiasts and mil-spec shooters the period-correct look and feel of the original M16 carbine.

The stock is molded from durable black nylon with a clean black finish that pairs naturally with classic A1-style furniture and installs as a direct fit on standard AR-15 / M16 lower receivers.

Whether you are building a retro kit, restoring a vintage rifle, or simply prefer the classic A1 lines over a modern collapsible stock, the BS-A1K delivers the iconic fixed buttstock that defined the early M16 series.
