B5 Systems Enhanced SOPMOD AR-15/M4 6-Position Collapsible Stock - Black

The B5 Systems Enhanced SOPMOD Stock is a 6-position collapsible buttstock for AR-15 and M4-pattern rifles equipped with a mil-spec carbine receiver extension. Its adjustable length of pull and Sure-Grip-style latch provide straightforward position changes while preserving the Enhanced SOPMOD profile and ergonomic cheek weld.

The stock body is made from glass-reinforced polymer with steel mounting hardware and a black finish. A cushioned, non-slip buttpad provides a stable shoulder interface, while dual molded-in, water-resistant battery compartments keep small essentials contained within the stock.

Sling attachment options include fixed sling mounts and steel anti-rotation quick-detach sling sockets. This model has no accessory rails or swivel studs and weighs 11.80 oz.

This New listing includes the Enhanced SOPMOD stock only. The receiver extension/buffer tube is not included, and the stock is intended for mil-spec rather than commercial-size receiver extensions.
