Description
The Magpul CTR (Compact/Type Restricted) Mil-Spec is a drop-in stock for AR15/M4 and AR10/SR25/M110 carbines on Mil-Spec receiver extensions. Its streamlined A-frame profile avoids snagging and shields the ambidextrous release latch against accidental activation, while the supplemental friction lock takes the wobble out of the fit. It carries an integral ambidextrous QD sling mount, two footman’s loops, a lanyard hole at the toe and a 0.3 in anti-slip rubber butt-pad, with a chrome-silicon lock spring. Specifications from Magpul: 8.9 oz stock only (12.7 oz with tube), 7.0 in long, 5.2 in high, 1.7 in wide, 3.3 in of LOP adjustment (about 10.3 in collapsed to 13.6 in extended). Compatible with CTR cheek risers. Choose Black, Flat Dark Earth or Olive Drab Green.
