B5 SIERRA K STOCK BLACK

The B5 Systems Sierra K Stock in black is designed to enhance compact weapon systems and personal defense weapons (PDWs) with a streamlined, space-conscious profile. Its reduced overall size and slim cheek weld provide a comfortable, ergonomic fit without adding bulk, making it ideal for users seeking efficient handling in confined spaces.

This stock features a snag-free adjustment lever for smooth length-of-pull customization, along with limited rotation quick-detach (QD) sling mounts and integral fixed sling attachment points. Internal tensioners contribute to a secure, rattle-free fit, while the anti-slip buttpad ensures stable shoulder placement during use.

The Sierra K mounts easily via a shortened compact Mil-Spec receiver extension, compatible primarily with AR-style rifles. Crafted by B5 Systems, this stock balances compactness with functionality, offering a reliable upgrade for shooters requiring a minimalistic yet practical stock solution.
