B5 Systems CPS-1400 Collapsible Precision Stock Short Black AR-15/M4

The B5 Systems Collapsible Precision Stock (CPS) in the Short configuration delivers a precision-fit buttstock engineered for the AR-15/M4 platform. Built from high-strength polymer in a black finish, the CPS brings B5's signature durability together with the adjustability demanded by precision rifle builds and modern sporting rifles alike.

Designed to drop directly onto a Mil-Spec carbine or A5 receiver extension, the Short CPS features an adjustable cheekpiece for a repeatable weld at the optic line, a cushioned buttpad to tame felt recoil, and integrated ambidextrous sling mounts for both left- and right-hand carry. The shorter length of pull makes it a natural fit for compact builds, CQB applications, and AR-15/M4 platforms where a streamlined stock is preferred over longer full-length alternatives.

At an overall length of 8.5 in, width of 2.0 in, and height of 4.35 in, the CPS Short weighs 23.2 oz - light enough to keep rifles maneuverable while still offering the rigid cheek weld and stable shoulder purchase that precision shooters require. Model CPS-1400.
