Description
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.
