Luth-AR BAP-1 Buffer Tube Assembly .223 Rem Black Aluminum AR-15

The Luth-AR BAP-1 is a complete fixed rifle-length buffer tube assembly built for the .223 Remington AR-15 platform. This drop-in kit gives builders everything they need to assemble a new .223 / 5.56 NATO AR-15 rifle with a traditional A2-style fixed stock recoil system, or to convert an existing AR-15 carbine back to a full rifle-length buffer configuration.

The assembly is machined from 6061-T6 aluminum and finished in a durable hardcoat anodized black for long-lasting corrosion resistance and wear under repeated shooting cycles. The buffer tube itself measures 15.3 inches in length and the complete assembly weighs 11.2 oz, with a 5.1 oz buffer matched to the spring and tube for reliable cycling.

Designed specifically as a rifle-length fixed buffer tube assembly for AR-15 rifles chambered in .223 Rem / 5.56 NATO, the Luth-AR BAP-1 arrives complete with the buffer tube, buffer, and buffer spring - everything required to install directly to the lower receiver and finish out an A2 fixed-stock build without sourcing individual components.
