B5 Systems CAR15 Retro Carbine Stock – Black

The B5 Systems CAR15 Stock (brand part number CAR-1353) is a Black retro-style carbine stock built to recreate the look and feel of the original CAR-15 stock on a modern Mil-Spec buffer tube. B5 Systems designed it for shooters building a retro AR clone who still want a correctly proportioned, period-accurate stock instead of a modern low-profile design. It mounts to any standard Mil-Spec carbine buffer tube, so it drops onto most existing AR-15 lowers without a receiver extension swap. It’s a lightweight, purpose-built stock for anyone finishing a retro-styled AR-15 build.
