B5 Systems Enhanced SOPMOD AR-15/M4 OD Green Polymer Collapsible Stock

The B5 Systems Enhanced SOPMOD is a purpose-built collapsible buttstock engineered for AR-15/M4 platforms running a Mil-Spec carbine receiver extension. Molded from reinforced polymer and finished in OD Green, this stock delivers the ruggedness and fit that have made the SOPMOD a staple on duty rifles, while keeping overall weight to just 11.80 oz.

Designed around an ergonomic cheek weld and a no-slip cushioned buttpad, the Enhanced SOPMOD promotes a consistent, comfortable shooting position shot after shot. Color-matched steel hardware is paired with overmolded anti-rotation quick-detach (QD) sling mounts and fixed sling points, giving you multiple ways to run a two-point or single-point sling. A positive suregrip stock latch keeps the stock locked to the receiver extension under hard use.

Two integrated water-resistant storage compartments provide a discreet place to stow batteries or small parts in the field, and the Sure Grip surface texture helps your support hand stay planted during transitions. Measuring 7.40 in long by 4.90 in tall, the SOPMOD rides naturally on the shoulder without snagging on kit.

The receiver extension tube is not included; this stock fits all Mil-Spec carbine receiver extensions on standard AR-15/M4-pattern rifles and is built to Mil-Spec materials and finishes.
