- Slim-profile cheek weld keeps the stock streamlined
- Low-profile, snag-resistant adjustment latch

The B5 Systems Sierra K is a reduced-size adjustable stock built around compact AR and PDW-style configurations. Its shorter footprint, slim cheek profile, internal tensioners, and multiple sling mounting options provide the core functions of an adjustable stock while taking advantage of B5’s shortened Sierra K receiver extension system.
Note: The Sierra K is designed for the B5 Systems Sierra K Receiver Extension Kit, sold separately. B5 states that the stock can also be installed on a standard-length mil-spec buffer tube, but it will not fully collapse.
