Magpul Industries CTR Carbine Stock Mil-Spec OD Green Polymer for AR-15/M16/M4

The Magpul CTR (Compact/Type Restricted) Carbine Stock in OD Green is a drop-in replacement buttstock engineered for AR-15, M16, and M4 carbines equipped with a mil-spec sized receiver extension tube. Built around a streamlined, snag-free profile, the CTR has been a benchmark for collapsible carbine stocks since its introduction, combining rugged construction with practical sling mounting and shooter-friendly ergonomics.

The stock is molded from reinforced polymer in an OD Green finish and uses a friction-locking, 6-position collapsible adjustment lever for fast, repeatable length-of-pull changes without secondary lock-down hardware. The lever itself sits recessed along the bottom of the stock to prevent accidental release and to keep the overall line of the stock clean. Adjustable length of pull runs from 10.50" to 13.80", allowing the stock to be set up for a wide range of body types and kit configurations.

The toe of the stock is capped with a removable 0.30" rubber butt-pad that cushions the shoulder and helps keep the stock planted during recoil. A Made in USA build, the CTR installs as a direct replacement for the factory carbine stock on any mil-spec buffer tube application. Buffer tube is not included.
