The B5 Systems Collapsible Precision Stock in FDE (Flat Dark Earth) Long is a precision AR-15 stock built for shooters who demand a repeatable cheekweld and rock-solid ergonomics. This Mil-Spec carbine receiver extension stock combines the proven cheek profile heritage of B5's SOPMOD and Bravo lines with modern adjustability—dial-tuned cheekpiece and buttpad work together so your sight picture stays consistent shot after shot. It's a serious upgrade for long-range accuracy work, competitive shooting, or any build where precision matters.

What sets the Precision Stock apart is its obsessive attention to detail. Ten internal tensioners keep everything locked down without rattle or play. The cheekpiece and buttpad both dial-adjust for a custom fit, and the buttpad won't slip even under sustained recoil. Gross length-of-pull adjusts via a pull-down lever with a lockout feature so you won't accidentally shift it mid-string. The long version is specifically optimized for side-charging uppers and rifles running a LAW side-folding adapter, giving you a compact package without sacrificing reach when you're behind the gun.

The FDE finish is color-matched with hardware that's both functional and clean. You get fixed sling mounts and steel quick-disconnect mounts that won't rotate. Underside M-LOK slots let you mount accessories where they belong—out of the way. The whole assembly is made in the USA from Mil-Spec materials and finishes, designed to handle the recoil and harsh environments real shooters put their rifles through. This is the stock that lets you dial in comfort and consistency, not compromise on either.
