B5 Systems Collapsible Precision Stock Long AR-15 Black - Mil-Spec - Adjustable Cheekpiece

The B5 Systems Collapsible Precision Stock (CPS) Long is a fully adjustable buttstock purpose-built for precision AR-platform rifles. Molded from a tough black polymer body, this stock drops directly onto any Mil-Spec carbine-length receiver extension, making it a direct-fit upgrade for AR-15 and M4 builds.

The CPS Long is engineered around a refined shooting position. An adjustable cheek riser and multi-position length-of-pull adjustment let the shooter dial in a custom fit, with the comb height ranging from 4.35" to 4.78" and the length of pull spanning 8.5" to 9.2" for repeatable cheek weld and consistent eye relief behind optics.

Built with B5's mission-driven construction, the CPS Long integrates anti-rotation QD sling mounts for secure push-button sling attachment, and the lightweight polymer keeps overall weight to 23.68 oz. Dimensions measure 8.5" long by 2" wide by 4.35" tall.

Ideal for precision AR, DMR, and general-purpose builds, the B5 Systems CPS-1412 delivers the fit, function, and durability expected from a professional-grade buttstock.
