Description

The B5 Systems Sierra K is a compact stock for AR-15 platforms, designed for PDW and other compact weapon systems. It features a reduced overall size, a slim cheek profile, and a low-profile adjustment latch that is designed to avoid snagging. The stock uses color-matched steel hardware and includes internal tensioners and an anti-slip buttpad.

The stock offers ambidextrous fixed sling mounts and limited rotation quick-detach mounts. It is built to Mil-Spec materials and finishes and is finished in Coyote.

It mounts to a shortened compact Mil-Spec receiver extension. The Sierra K Receiver Extension Kit is sold separately and is required. The stock will not fully collapse on a standard length Mil-Spec buffer tube.
