STR

The Magpul STR is a storage-capable drop-in replacement buttstock for AR-15/M4 carbines using mil-spec sized receiver extension tubes. The reinforced polymer A-frame design adds two water-resistant battery storage tubes along the cheek weld area, each holding up to two CR123A or AA batteries. It features an ambidextrous release latch and friction-lock system, two integral sling loops, a reversible push-button QD sling mount, and a replaceable 0.30" thick rubber butt-pad.
