The Magpul Enhanced Receiver Extension is a 10-position, Mil-Spec sized, SR25/M110 profile* buffer tube optimized to fit with the full line of Magpul Mil-Spec Carbine Stocks.
Due to its longer length, this receiver extension is compatible with most DPMS® Gen 1 pattern 7.62x51 firearms with standard length AR15/M4 carbine buffer components as well as aftermarket A5 buffers and springs for use on 5.56x45 AR15/M4 platforms.*
Constructed of impact extruded 7075-T6 aluminum with Type III, Class 2 hard coat anodizing for an extremely hard, abrasion resistant surface. The interior of the receiver extension features Everlube® coating for enhanced corrosion resistance and reduced friction and wear. The additional position holes allow for more length-of-pull fitment options.
Made in U.S.A.
*NOTE: An aftermarket short buffer will be required to utilize this tube with the Bushmaster® BAR-10 and Rock River Arms® LAR-8. Not compatible with the HK®417/MR762A1.
