| Does anyone know if the hydraulic buffers actualy reduce felt recoil? I have a 308 RR LAR 8 with a 16" barrel and the recoil is excessive. A scope I've used on other 308 rifles broke in about ten rounds. What about the heavier buffers, do they help? Thanks to all who reply. |

Yes, they can help.
What type of scope/mount and what type of failure did you have with your scope? (The buffer may or may not fix this problem.) The buffer has its largest affects on the part of the recoil pulse after the bolt comes back. This happens after the shock pulse from ignition and projectile acceleration has already peaked. What we feel in terms of recoil and what affects the scope can be very different. Spring airguns can break some scopes and they are only launching a little pellet for example. |

If it was an NcStar scope then don't pay a bunch of money on a buffer when you 'should' pay more for a proper quality scope for that nice 308.
If it was a decent scope (paid damn good money for) then the vendor or manufacturer should be contacted because that's where the problem is. Recoil is an entirely separate issue. |

Hydraulic buffers work to some extent, until they fail. My heavy buffers have no moving parts to wear out, no messy fluid (or powder) to leak and carry a lifetime warranty. If you can break it in normal use, I'll replace it. www.heavybuffers.com |
I'm sure Slash's is also a viable option but Enidine also guarantees their buffers for life according to the packaging. Brownells also guarantees the Enidine Buffers for life according to their video. I was initially concerned by the possibility of a failure but my AR is not for combat and if the hydraulic buffer breaks, my AR will still cycle it'll just hurt like hell until I pop in a stock 308 buffer and get the Enidine replaced. But while the Hydraulic Buffer is working I get the full benefits of reduced recoil.

They well start to leak sooner or later, if you have the paper work it can be replaced under warranty. IMHO a heavy buffer is much better solution, nothing to fail. I have two AR10's and the recoil is very mild compared to the M14's or M1 Garands I shoot. |

But if your M14 or M1 Garands had a Hydraulic Buffer it would be a different story

Thanks for all the replies. As far as the scope it was old but had been used a lot on an M1A. The internals broke some how. The windage no longer moved with the knob. The felt recoil is way more than my M1A. I,ve read as much as I could find on the net, but really wanted to hear from owners on this site. I found another type of buffer by MGI. It has moving parts but says no air or liquid. That's about all I could find about it, other than a few folks think it works. My current stock buffer is 6 ounces. I'm was pretty much thinking of the Enidine because it was guaranteed and this is not a life or death rifle. Now I hope to find out more about the MGI.
Thanks again |
I understand the concept of the heavy buffer. More mass slows the action down and requires more energy to be used to move the buffer. So then you use a stronger spring. So my qwestion is, on the return stroke won't the heavy buffer and spring slam the action closed harder? Cause more wear and tear on the bolt and locking lugs. Also wouldn't the slam forward disturb you aim for the second shot? Like on an open bolt weapon?

Also wouldn't the slam forward disturb you aim for the second shot? Like on an open bolt weapon? David Tubbs sells a bolt carrier weight system, so I'm guessing the concern about the next shot is not a concern. The action cycles quickly, you could argue that the harder forward impulse helps push the barrel back down on target. More weight is less recoil. Basic physics, same force moving more mass displaces mass a smaller distance. A barrel brake may be a better way to reduce recoil, or simply add more weight to the rifle. |

Ive messed with the MGI buffer and a 308, it works to reduce felt recoil to some extent in the 308 in my opinion. |

It is far less stress than firing and unlocking Also wouldn't the slam forward disturb you aim for the second shot? Possibly, but again,the firing,unlocking and stop at the back of travel will affect it more Like on an open bolt weapon? Open bolt sight issues happen after the trigger is pulled, but before actual firing, vs after the bullet has left the barrel. You could make the argument that an open bolt weapon would have a faster followup shot since only the second half of the cycle happens after firing. The first half spoiled your initial shot! |

If you want the lightest recoil possible, get a JP low mass system with adjustable gas block and a muzzle brake. |

With that said, I recommend using the heaviest buffer and spring that will work in a gun to reduce wear and tear. F=1/2(MV^2), so velocity is the most important component, not mass. With a heavier buffer the BCG is moving slower in both directions. There is no increase in force. |
