Magpul Stock CTR M4 Carbine, Mil-Spec
The Magpul CTR (Compact/Type Restricted) - Mil-Spec model is a drop-in replacement buttstock for AR15 / M16 carbines using Mil-Spec sized receiver extension tubes. Designed for light, fast action, the streamlined A-frame profile avoids snagging and shields the release latch to prevent accidental activation.
The CTR also features a supplemental friction lock system that minimizes excessive stock movement for enhanced weapon stability and an ambidextrous QD sling mount that will accept any push-button sling swivel. The Mil-Spec model includes a standard 0.3" thick rubber butt-pad, which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.

Excellent product
Once again the crew at Magpul have put forth a superior piece of equipment at a reasonable price. This stock replaced a factory issue in seconds. It locks rock solid to the extension tube. The only play in my rig now is that little bit of wiggle between the upper and lower. If cheek weld is an issue they have a solution for that but you do have to purchase it separately. Highly recommend this to the shooter that wants to tighten things up in the rear. QD swivels pop right in for two point mounts. Comes in commercial and mil-spec diameters. One note: I tried to put one on a Rock River Tactical Entry carbine (which is commercial dia) and it did not lock down tight on the tube. I'm sure its something with the tube RRA uses. BTW, the mil-spec didn't fit; I tried that. I've put in calls and emails to their tech support to resolve this issue but (big surprise) noone has gotten back to me. I've had no such problem with the tubes other manufacturers are using.
