Frequently Asked Questions
Will the Magpul CTR fit my AR-15 if it has a commercial-spec buffer tube?
No — this version of the CTR is designed specifically for mil-spec diameter receiver extension tubes (approximately 1.148" outer diameter). Commercial-spec tubes are slightly larger and have a different taper. If your AR-15 has a commercial buffer tube, you would need either the Magpul CTR Commercial-Spec model or to replace your buffer tube with a mil-spec unit. When in doubt, measure your tube or check your lower receiver manufacturer's specs before ordering.
Does the friction lock really eliminate stock wobble, and is it adjustable?
Yes — the CTR's supplemental friction lock is one of its standout features. It applies light, consistent pressure against the receiver extension tube, dramatically reducing the side-to-side and rotational play common in standard mil-spec stocks. The lock is engaged or disengaged via a small lever on the underside of the stock. When released, the stock adjusts freely across its length positions just like a standard carbine stock. It's a simple but highly effective system that improves cheek weld consistency and overall feel during rapid fire.
Can I attach a single-point or two-point sling directly to the CTR stock?
Yes — the Magpul CTR features an ambidextrous QD sling mount that accepts any standard push-button quick-detach (QD) sling swivel, making it compatible with the vast majority of modern two-point and single-point convertible sling systems. The mount is recessed into both sides of the stock for a low-profile fit that won't snag on gear. Note that the stock does not include a sling swivel — you'll need a compatible QD swivel, which is typically sold with most quality tactical slings.
