The MDEK TRRR recoil elimination butt stock for AR10 .308 cal. rifles eliminate painful felt recoil and barrel rise. Makes the AR10 a good hunting rifle especially in states that do not allow hunting with a .223 cal. AR15 since it is only .22 cal. Built of high strength steel and 7075-T6 alloys and finished in hard flat black powder coat. This is the only real recoil elimination stock that really works. A real good effective butt stock for just $89.95. Other so called recoil reduction stocks sell for twice the price and do nothing.
