Kynshot RB5006 AR-10 .308 Fixed Stock Hydraulic Recoil Buffer - Stainless Steel

The Kynshot RB5006 is a hydraulic recoil buffer engineered for AR-10/.308 rifles equipped with Mil-Spec rifle-length A1 or A2 fixed stock buffer tubes. Purpose-built to tame the heavy recoil of larger .308/7.62mm AR-10 platforms, this buffer reduces felt recoil by up to 30%, allowing for noticeably faster and more accurate follow-up shots on the range or in the field.

Machined from 17-4 stainless steel, the RB5006 measures 5.81" overall (5.25" when compressed) with a buffer diameter of 0.75" and a weight of 7.7 ounces. The unit is sealed with Mil-Spec hydraulic fluids for reliable, long-lasting damping performance under repeated firing cycles. Its dimensions and construction make it a direct drop-in upgrade for any AR-10 build using a 9.5" internal fixed-stock buffer tube.

Tested and vetted by law enforcement professionals, the RB5006 installs in place of a standard AR-10 fixed-stock buffer and requires no modifications to the firearm. Whether you run a precision .308 AR-10 hunting rifle, a hard-use duty carbine, or a recreational .308 build, this hydraulic buffer delivers tangible improvements in recoil management, muzzle rise control, and overall shooter comfort.
