The B5 Systems AR-15 Collapsible Precision Stock (CPS) Long delivers the stability of a fixed stock combined with the adjustability of a modern carbine stock. Built from durable polymer with 12 internal tensioners, it eliminates rattle when mounted to a carbine length mil-spec buffer tube. The design builds on the proven cheek profile found in B5’s SOPMOD and Bravo stocks, adding an adjustable cheekpiece and buttpad that work with Mil-Spec carbine receiver extensions.
The wide cheek rest supports a consistent cheek weld and features elevation adjustment, while the rubber butt pad extends to match your scope height and head position. Length of pull adjusts via pull-down mechanism with lockout, and the stock includes internal tensioners, ambidextrous fixed and quick disconnect sling mounts, underside M-LOK accessory mount, and color-matched hardware. The CPS long model accommodates side charging and LAW side folding adapter equipped rifles.
Manufactured to Mil-Spec materials and finishes in the USA, this FDE-colored stock suits AR-15 builds that prioritize precision and reliability. Anti-rotational QD mounts, fixed sling mounts, and bottom-mounted M-LOK slots enable attachment of monopods and other accessories.
