The Magpul®Enhanced Rubber Butt-Pad, 0.70" is an optional replacement butt pad for the CTR®and MOE®Mil-Specstocks as well as the original UBR®, all STR®, ACS-Land ACSstocks. It is designed for enhanced shoulder purchase as well as offering slightly improved recoil reduction with its thicker, vented construction. The Enhanced Rubber Butt-Pad can also be installed on Commercial-Spec MOE®/CTR® stocks, but may prohibit use of fully collapsed position due the extended, slanted back of most commercial-spec receiver extensions. All mounting hardware included. Made in U.S.A.
