Armaspec SRS Buffer Kit, AR10

The Armaspec SRS Buffer Kit for AR10, Gen 4 (brand part no. ARM263-AR10) is a complete enhanced buffer tube kit sized for AR10-pattern .308 rifles. Armaspec built the kit around a mil-spec 7075-T6 six-position buffer tube along with a steel castle nut and end plate, then paired it with a Stealth Recoil Spring (SRS) buffer scaled to the heavier bolt-carrier group and stronger recoil impulse of a .308-class AR. The SRS design keeps the spring from rubbing the tube wall for quieter cycling, and its second recoil-reduction stage helps tame the harder-hitting recoil impulse of a big-bore AR platform. Bundling the tube, hardware, and buffer together makes this a straightforward, single-purchase upgrade for an AR10 build.
