Carbines are weapons that are hard to master and dangerous to use. They slip easily and need extreme care when operated under any circumstances. This is why Magpul created accessories to help the operator use this highly dangerous equipment with safety and confidence. It is the enemy you want to get, not yourself after all. The Magpul CTR is a collection of buttstocks and compatible accessories designed to make the operating of carbines easier and safer.
The Magpul CTR (compact/type restricted) is a buttstock replacement device that comes both in military and commercial specification models. It is designed for a firmer weapon grip and is very light and practical. It is compatible with AR15/M16 carbines and uses either military of commercial spec receiver extension tubes. It has a typical a-frame shape when seen from the side, which helps avoid snagging and protects the release latch so that accidental activation is made impossible. The stock is extremely stable thanks to an advanced friction lock system used supplementary on the device.
It also features a QD sling mount compatible with most types of push-button sling swivels. The rubber butt pad which is included is a standard 0.30 inch and helps avoid the weapon from slipping off armor or other smooth equipment used. Magpul also offers an amazing enhanced rubber butt pad, for even more stability and security, which can be ordered separately. The Magpul buttstocks are also compatible with the comfortable Magpul cheek riser, which comes in black and is easily adapted onto your CTR
To choose between the military or commercial spec you just need to check what the spec of your extension is. Depending on the type of the latter, you should get the compatible stock for it.
