Frequently Asked Questions
Will the Magpul CTR fit my existing AR-15 receiver extension tube?
The Magpul CTR Mil-Spec model is designed specifically for mil-spec diameter receiver extension tubes (approximately 1.148" outer diameter). It is not compatible with commercial-spec tubes, which have a slightly larger diameter. If you're unsure which tube your rifle uses, measure the outer diameter or consult your lower receiver manufacturer's documentation before ordering.
What is the friction lock system and how does it improve shooting performance?
The CTR's supplemental friction lock is a tightening collar that applies pressure against the receiver extension tube, effectively eliminating the wobble and rattle commonly associated with standard mil-spec carbine stocks. This results in a more consistent cheek weld and improved shot-to-shot stability — particularly beneficial during rapid-fire drills or when using magnified optics that amplify any stock movement.
Can the rubber butt-pad be removed or replaced on the Magpul CTR?
Yes. The 0.30" rubber butt-pad on the Magpul CTR is fully removable, allowing shooters to reduce overall stock length or swap it out for an aftermarket pad if desired. The butt-pad is designed to provide positive shoulder purchase and prevent slippage, even when worn over plate carriers, chest rigs, or other modular body armor setups.
