Enidine "AR-Restor" Hydraulic Recoil Buffer for 7.62mm/.308 AR Rifle - collapsible stock (2.5")
This is the best buffer on the market today for AR style rifles! Reduce felt recoil, increase reliability, reduce shock and vibration to optics, reduce bolt carrier speed, suppress bolt bounce, and reduce wear on parts with this simple drop-in replacement. You will feel less recoil and smoother operation with this buffer! This buffer has a piston that is hydraulically dampened to absorb the shock of impact from the bolt carrier and to prevent bolt bounce.
Buffer is 2.5" in length and replaces buffers that are 2.5" long. Designed for 7.62mm/.308 AR style rifles with an AR-15 length collapsible stock tube which is 3/4" shorter than an Armalite AR-10 stock tube. This is a common factory stock arrangement on many factory .308 rifles such as DPMS, Knight's, LWRC, POF, Larue, PWS and many others. Also works well with other calibers based on the .308 case such as the .338 Federal, .260 Rem and .243 Win. If you buy an aftermarket AR-15 collasible stock and stock tube (receiver extension) for your .308 AR, this is the buffer you will need to go with it. The Magpul UBR stock uses an AR-15 carbine length stock tube and would also require this buffer if used on a .308 rifle.
