Frequently Asked Questions
Will the Magpul CTR fit my AR-15's existing buffer tube?
The CTR Mil-Spec model is designed specifically for mil-spec sized receiver extension (buffer) tubes, which have an outer diameter of approximately 1.14 inches. If your AR-15 came with a factory mil-spec tube — as most do — this stock will drop in with no modifications. Note that commercial-spec tubes have a slightly larger diameter and are not compatible with this version; Magpul offers a separate commercial-spec CTR for those builds.
What makes the CTR different from the Magpul MOE SL or ACS stocks?
The CTR's standout feature is its supplemental friction lock, which tightens the stock against the buffer tube to eliminate the wobble and rattle common in standard six-position stocks. Compared to the MOE SL, the CTR adds this friction lock and a shielded latch release. The ACS (Adaptable Carbine Stock) adds internal storage compartments and a heavier profile — the CTR strikes the balance between feature-rich and lightweight for shooters who prioritize a streamlined, fast-handling setup.
Can I attach a QD sling swivel directly to the CTR stock?
Yes. The Magpul CTR features a built-in ambidextrous QD sling mount that accepts any standard push-button quick-detach sling swivel. This allows for rapid sling attachment and removal on either side of the stock, making it easy to transition between carry positions or switch to a two-point sling configuration without additional adapters or hardware.
