| Anyone using the stainless h9 9mm buffer from eBay if so like to know some details on how it is working thanks |

Never heard of it before. It's an 8oz buffer that has an extended length, apparently attacking two "problems" at once.
The following is unsolicited advice, but for anyone building a 9mm AR, I think it's important to at least consider these points. First off, heavy buffers aren't necessarily needed in a 9mm AR. I personally think it's important to see how the gun runs with a standard part before you invest in a fancy part. Not that this buffer is particularly expensive, but the extra weight may not be needed. Second, spacers or extra-long buffers address a potential problem that not everyone ever experiences. The only time a spacer is indicated is when you have bolt overtravel backward enough that the bolt smacks the end of the receiver extension and/or the bolt slams forward too violently - which can lead to broken bolt catches. Again, adding a spacer is not something I recommend doing until and unless it's needed. My SBR lower runs my 10" AND 16" 9mm upper just fine with a stock carbine buffer and no spacer, shooting everything from "NATO" grade 124 gr loads to Winchester White Box 115 gr FMJs without a hitch. There are TWO situations where I'd recommend trying a heavier buffer to start with: running a suppressor, and running a select fire lower. A blowback gun with a suppressor WILL need extra mass to keep closed until chamber pressure drops off enough. A select fire lower (an expensive and relatively rare commodity) may be fine with a standard carbine buffer, but I personally would work down in buffer weight until you got the gun running smoothly, to protect the FCG pin holes. I'll shut up now. I hope to see some posts from people who've tried this buffer, and how it's performed for them. |
