The B5 Systems Collapsible Precision Stock in OD Green (Long) brings shooter-proven ergonomics and adjustability to your AR-15 platform rifle. Built on B5's legacy of combat-tested cheekrest profiles, the CPS Long combines precision optics support with practical field features—making it equally at home on a precision rifle at distance or a tactical setup running accessories. The Long variant is optimized for side-charging rifles and pairs seamlessly with LAW side-folding adapters, giving you genuine flexibility in how you configure your gun.

What sets this stock apart is the attention to details that matter in real shooting. The adjustable cheekpiece and buttpad dial in independently, so you can establish a repeatable weld regardless of your optic height or shooting position. Ten internal tensioners eliminate rattle and wobble in the receiver tube, while the underside M-LOK slot lets you mount gear exactly where you need it. The pull-down lever adjustment mechanism features a positive lockout, so your length of pull stays where you set it—no creep, no surprises. Both fixed and quick-disconnect sling mounts are built in, and the QD points use steel anti-rotation hardware that won't spin loose.

Fit and finish reflect B5's USA manufacturing standard. The stock accepts Mil-Spec carbine receiver extensions (M4, A5, and M110K tubes), and all hardware is color-matched to the OD Green finish for a cohesive, professional look. The cushioned buttpad resists slipping under recoil, and the whole package weighs a practical 20.65 ounces.
