B5 Systems SOPMOD Stock – Government Version, Mil-Spec, Black

The B5 Systems SOPMOD Stock, Government Version (brand part number SOP-1351) fits a mil-spec AR-15 receiver extension in black and carries an ergonomic cheek weld shape for a consistent stock weld behind a red dot or magnified optic. B5 Systems uses color-matched steel hardware throughout and builds in fixed sling mount points for a sling attachment without extra hardware. A no-slip cushioned buttpad softens recoil against the shoulder, and dual storage compartments add onboard space for spare parts or a cleaning kit. As an AR-15 accessory built to government-contract specifications, it’s a straightforward, durable stock for a duty or range-focused build.
