KYNSHOT - Hydraulic Recoil Buffer for AR-10 with collapsible stock (3.25")

In our experience, this is the softest running AR buffer on the market. It shock absorbs more than any other buffer design and makes a noticeable difference in recoil and shot recovery. Reduce felt recoil, improve reliability, reduce bolt carrier speed, reduce wear on parts, reduce shock and vibration to optics, and suppress bolt bounce with this simple drop-in replacement. Designed for AR-10 rifles with a collapsible stock that use the longer buffer tubes that are 7.75" on the inside. This buffer has a piston that is hydraulically dampened to absorb the shock of impact from the bolt carrier's rearward motion and to prevent bolt bounce as a new cartridge is chambered. You will feel less recoil and smoother operation with this buffer and you will see less movement of your sights during recoil for faster shot to shot recovery time. Replaces buffers that are 3.25" in length.

This buffer is made to the highest quality and durability standards. Can take all the punishment your rifle can dish out. Constructed using 17-4 Stainless Steel and is built to outlast your gun. The hydraulic seal and porting technology used in this buffer has been thoroughly proven which is why the warranty on this buffer is as impressive as it is. Designed for 7.62mm/.308 AR-10 type rifles with an AR-10 length collapsible stock buffer tube which is 7 3/4" long on the inside (AR-15 collapsible buffer tubes are 7" on the inside). This size buffer tube is used on factory collapsible stock .308 rifles such as those made by Armalite, Sig, LWRC, S&W M&P 10, and many others. The best way to confirm is to measure the length of the buffer that came with the rifle from the factory. This buffer model is the same length as the .223 collapsible stock Kynshot buffer, but it is 0.7 ounces heavier, slightly larger diameter and has a thicker piston head and piston shaft as well as different hydraulic porting to handle the greater mass of a .308 bolt carrier.

This buffer is also a great option for heavier caliber AR-15 carbines and piston guns that run hard. For .458 SOCOM, 450 Bushmater, 6.5 Grendel, and many SBRs and Piston guns, this is THE buffer to use. It will make a very noticeable difference in the recoil, cycling and shot recovery time and it can take the abuse of the harder running AR-15s as well as the 308 ARs.

Works with factory buffer springs. Or for the greatest improvement, upgrade your buffer spring to either a Sprinco AR-15 Carbine Extra Power Buffer Spring (their Red Spring), or for the most strength you can use the Sprinco 308 Carbine Buffer Spring (their Orange Spring). The JP .308 carbine buffer spring is slightly less powerful than the Sprinco Orange Spring and it runs the most quietly.
