The Magpul CTR (Compact/Type Restricted) - Commercial-Spec model is a buttstock designed as a drop-in replacement for AR15/M16 carbines using Commercial-Spec sized receiver extension tubes. It has a streamlined A-frame profile to avoid snagging and prevent accidental latch activation. Additionally, it features a supplemental friction lock system to minimize unnecessary stock movement and increase weapon stability. It also has an ambidextrous QD sling mount compatible with any push-button sling swivel.
The Commercial-Spec model comes with an extended 0.55" thick rubber butt-pad that accommodates the longer, slanted back common in most Commercial-Spec tubes. This feature provides a comfortable shoulder purchase and increased impact protection. The sloping cheek weld balance is designed to provide both a slim profile and user comfort. Side mounting slots accept optional cheek risers for non-AR15/M4 applications, making it versatile.
The Magpul CTR is compatible with various sling attachments, including Magpul ASAP®, ASAP® QD, and other receiver-mount sling attachments. It has rear push-button QD swivel sling mounts, accommodating up to 1.5” swivels, making it ambidextrous. It also has rear/bottom 1.25” sling loops toe-lanyard, offering more customization options for para-cord rigs.
The CTR weighs 9.3 oz, while it weighs 13.6 oz when combined with the receiver extension tube. It has an LOP adjustment range of 3.8 in and a maximum length of 7.2 in. The Commercial-Spec model is compatible with carbine receiver extension tubes of Commercial-Spec sizing from manufacturers such as Bushmaster, DPMS, and others.
In comparison to other buttstocks, the Magpul CTR (Compact/Type Restricted) - Commercial-Spec model has a streamlined A-frame profile to avoid snagging, a supplemental friction lock system to minimize stock movement, and an extended rubber butt-pad offering improved shoulder purchase and increased impact protection.
