Can someone explain the difference in buffers or point me to a link where it has already been posted? What performance benefit is there is there in an "H" buffer over an "H2" buffer vs a standard CAR or A2 buffer. I'm working on a lower build that will have a 6 pos stock with a 16" superlight barrel and want to buy the right part the first time. Thanks. |

3.8 oz H buffer 4.6 oz H2 buffer 5.4 oz H3 buffer The heavier a buffer you would use requires more force to cycle. Going to a heavier buffer will slow down the cyclic rate of the firearm, and affect the feel of the recoil. Unless you plan on sticking to only a particular brand of ammunition and bullet weight, or if you only reload, then you can tailor the use of a heavier buffer to your particular rifle and ammo choice. If you're not sure what ammo you'll be feeding, from the anemic to the heavy stuff, your best bet is just sticking with a standard carbine buffer. If you're going to shoot Wolf & RG .223, it would be best to stick with the standard carbine buffer. If you're only going to shoot 5.56 spec ammo, a H buffer should be just fine... the heavier buffers will only work when you're shooting hotter ammo and heavier bullets. I have no problem shooting BH 73gr Berger with my H2 buffer, but my standard H buffer will cause FTF with Radway Green. Haven't tried wolf, and don't plan to, but it may have reliability issues as well. |

"H" buffer works fine for me with Wolf and Winchester White Box as well as American Eagle and Federal 55gr. TRU. "H" buffers have come with both my RRA 6-Pos stock and my Magpul M93. I believe RRA puts them in all their carbines (except 9mm). I may try a standard carbine just to see how much quicker the rifle cycles. |
You info is pretty much right on, but I just want to interject that RG is 5.56 spec ammo, and it's not underpowering that causes folks shortstroking problems with it. I run RG in 3 9mm-buffered guns all the time |

I have an MGI buffer in my 1:7 twist 16" middy that uses nothing but 69+ grain ammo. Works awesome. I have a 9mm buffer in my 1:9 twist 14.5" CAR that uses 55-62 grain ammo I also have standard buffers & H buffers.... if I had to have a do it all buffer I'd stick with a 9mm buffer - they just work fantastic and I can feel a noticable difference in felt recoil. More of a push than pop. I find the gun easier to control...or if nothing else, more pleasant to control. All that said, standard buffers are called so for a good reason. They work well. Aftermarket gizmos aren't always warranted, recommended, or needed. |
air driven buffers? regardless, you're right about need. You have to take note that most 'aftermarket' buffers are meant for a specific scenario, not a general need. For example, the MGI buffer is designed to address the issue of erosion within the gas system. Yet...many people, myself included, found the MGI buffer to do an outstanding job negating felt recoil that stems from the cycling of the carrier. The Enidine is designed to slow cycling AND reduce felt recoil. So it does more than one thing. Same can be said about H, H2, and H3 buffers. Is that a bad thing? Absolutely not. That said, custom buffers are not without their drawbacks. They are limiting, but certainly add a benefit. Just depends what the benefit is worth to you....and more importantly your wallet.  My fav so far is the 9mm buffer. I find the MGI awesome, but it needs heavy ammo in my 16" middy to really notice the benefits. I haven't shot the light stuff (ie 55grain) through it, nor will I...so I can't vouch for it's overall reliability. |

I've been playing with a MGI buffer alot lately in both a 5.56 and 6.5mm Grendel, both with 16 inch barrels......so far I am very impressed. I took the 5.56 gun to a Tactical Response High Risk Contractor Medical Package and one of their Fighting Rifle courses back to back. Put 5,000 rounds of Wolf steel case through it in 7 days of training with only one malfunction. The MGI does indeed seem to smooth the recoil impulse down....especially in the Grendel......I like it..... |
not all RG is totally up to NATO 5.56 spec, the full power NATO spce stuff won't run in the current Brit guns, so they devoloped lower pressure stuff |
Incorrect. That is old info from six to ten years ago. The issues some folks have are due to pressure curve issues, not how hot it is or isn't loaded. |
