Overview
Built as a complete stock kit, this setup is intended for shooters who want a Mil-Spec diameter receiver extension, buffer, spring, end plate, and locking nut packaged with BCM’s Mod 2 stock. The included MK2 receiver extension is approximately 3/4" longer than carbine length and offers 8 positions, while the EPM4 end plate includes a mount for a QD swivel. BCM describes the Mod 2 stock as an improvement over the baseline M4 accessory, with enhanced ergonomics and durability. It is a practical choice for a rifle build or upgrade where a fully matched stock assembly is preferred over piecing components together separately.
