Luth-AR BS-M4 M4 Waffle Buttstock w/ Rear Sling Swivel - AR-15/M4

The Luth-AR BS-M4 is a fixed M4-style "waffle" buttstock with an integrated rear sling swivel and classic retro latch plate, designed as a direct replacement for the standard carbine stock on AR-15 and M4 rifle platforms.

Built from lightweight and durable BKV 130 nylon, the BS-M4 keeps installed weight to just 6.90 ounces while measuring 6.5 inches overall length. It is engineered to fit all Mil-Spec carbine buffer tubes and is not compatible with commercial-spec tubes. The signature waffle pattern on the rear face of the stock provides a positive shoulder purchase, while the integrated rear sling swivel provides a clean, dedicated rear sling attachment point without the need for aftermarket adapters.

Finished in black with the retro latch detail that defined the original M4 stock profile, the BS-M4 is a simple, lightweight upgrade or replacement for any Mil-Spec carbine-equipped AR-15 or M4.
