B5 Systems CAR-15 AR-15 OD Green Synthetic Mil-Spec Carbine Stock

The B5 Systems CAR-15 buttstock brings the classic CAR-15 carbine profile to the modern AR-15/M4 platform. Built as a retro-styled Mil-Spec carbine stock, this model gives your AR-Platform rifle the correct look and proportions of an iconic carbine-style replacement stock. The OD Green synthetic stock mounts directly to a standard Mil-Spec receiver extension tube (tube not included) for a quick, drop-on installation.

Molded from durable synthetic polymer in a non-reflective OD Green finish, the CAR-15 stock keeps weight to a minimum at just 4.2 oz. It fits all standard Mil-Spec size receiver extensions and measures 6.21 in long by 1.75 in wide for a compact carbine footprint that pairs cleanly with retro and modern AR builds alike.

Whether you are building a retro block clone or simply want the clean CAR-15 carbine silhouette on a modern build, the B5 Systems CAR-15 stock offers a lightweight, period-correct option for your AR-15 or M4 carbine.
