The B5 Systems Sopmod Government Ships in Plastic Bag, Mil Spec is a stock, offered in Black, Coyote.
Since 2011, B5 Systems has manufactured the Crane NSWC designed SOPMOD buttstock for the US Department of Defense. B5 is proud to offer the same stock to the public. The SOPMOD features color matched steel hardware, no slip cushioned buttpad, and dual water resistant storage compartments.
The stock sets your length of pull and cheek position, so it has a direct effect on how consistently you can build a position behind the rifle. Collapsible AR-15 stocks slide on to the buffer tube (receiver extension) — check whether your rifle has a mil-spec or commercial diameter tube, as the two are not interchangeable.
