The Magpul CTR Carbine Stock (brand part number MAG310-ODG) is a Compact/Type Restricted buttstock built as a drop-in replacement for AR-15, M16, and M4 carbines running a mil-spec sized receiver extension tube. Magpul shapes the CTR with a streamlined A-frame profile that resists snagging on gear and shields the release latch from accidental activation during hard use, backed by a supplemental friction lock system that minimizes excess stock movement on the tube for a tighter, more stable cheek weld. This Mil-Spec Model includes a standard 0.30-inch thick rubber butt-pad that provides positive shoulder purchase to prevent slippage even with body armor or modular gear in the way, and an ambidextrous QD sling mount accepts any push-button sling swivel for fast-attach carry options. This OD Green finish suits woodland and field builds, and the stock ships without a receiver extension tube, so confirm you already have a mil-spec tube on hand.
