The Magpul CTR Extended Butt-pad utilizes a firm rubber that is designed for enhanced shoulder purchase and improved impact/drop mitigation. May also be used with the Mil-Spec models as well as all STR®, ACS-L™, ACS™ and UBR® stocks for 0.25" increased length-of-pull.
Not compatible with MOE® Fixed Carbine Stock.
This will not provide any extra recoil cushioning as the rubber portion is the same thickness as our standard Rubber Butt-Pad, 0.30". An extra 0.25" of hard polymer is added to the back to provide the extra LOP.
