B5 Systems SOPMOD Stock Mil-Spec – AR-15/M4 (Gray)

The B5 Systems SOPMOD Stock delivers enhanced cheek weld and improved recoil management for AR-15 and M4 platform rifles. Its reinforced polymer construction and adjustable length of pull provide a stable shooting platform for precision work and rapid target transitions. The storage compartments accommodate batteries and small accessories without adding unnecessary bulk.

Built from high-impact reinforced polymer, this mil-spec model fits standard carbine buffer tubes and features a friction lock system to eliminate wobble. The textured buttpad provides a secure shoulder interface in all conditions. Six-position adjustability lets shooters customize length of pull from 10.5" to 14" collapsed to extended. Installation requires no gunsmithing—simply slide onto a mil-spec carbine buffer tube and lock in place.
