B5 Systems Enhanced SOPMOD AR-15/M4 Mil-Spec Woodland Camo Collapsible Stock

The B5 Systems Enhanced SOPMOD stock is a Mil-Spec collapsible buttstock for the AR-15/M4 platform, finished in Woodland Camo.

Built around a reinforced polymer body with color-matched steel hardware, the Enhanced SOPMOD uses double the resin and glass content of prior-generation SOPMOD designs for roughly two to three times the strength of its predecessor. The finished stock measures 7.43" long and weighs 11.80 oz.

Functional features include an ergonomic cheek weld, a non-slip cushioned buttpad, overmolded steel anti-rotational quick-disconnect (QD) sling mounts, and fixed front sling mounts for traditional sling attachment. Two integrated, water-resistant storage compartments let you stow batteries or small parts in the field.

Sized for a Mil-Spec receiver extension, this Enhanced SOPMOD drops onto any standard AR-15 or M4 lower equipped with a Mil-Spec buffer tube for an immediate upgrade in cheek weld, sling options, and on-board storage.
