BCM Mod 3 Stock — Black (Mil‑Spec AR‑15)

Description

Developed from operational experience, the BCM Mod 3 Stock refines the M4-style buttstock into a minimalist, snag‑free component. The Mod 3 is shaved down to 6.4 ounces while employing an improved double-walled H‑Beam construction for durability. Two friction‑fit M3 marksman risers, approximately 0.5" and 0.8", can be mounted in six positions and oriented forward or reverse to provide adjustable cheek weld. Designed for Mil‑Spec receiver extensions, the Mod 3 supports use with electro‑optics and low‑power variable optics including setups intended for passive night vision.
