I'm looking for a "universal" buffer that can handle 5.56 & 9mm rounds. I just want to change the uppers out and not deal with changing out the buffer & spring. Any suggestions?
I was looking at Spike's Tactical ST-SST which badazzar has told me it works for different setups. I was wondering if anyone has dealt use this with 5.56 & 9mm? Thanks |

RRA 9mm Buffer? Would this be able to handle the 5.56 as well? It shouldn't be a problem in any upper. Possibly if it's a SBR, 12" or shorter. No it's going to be a 16" barrel for the 5.56 Then a 9mm buffer will be a very nice upgrade. You shouldn't have any problems. |

Lots of guys on this board run 9mm buffers in their 5.56 rifles. 16'' barrels OK.
It's the same weight as an H3 buffer but doesn't have the same reciprocal weight. If you aren't running a FA gun you don't really need the recip weight. It's what I run in my pistol lower that I use for both 9mm and 5.56. |

Thanks for the info. By chance do you know the weight of the buffer? I actually do have a 9mm buffer, Spikes ST-9X which I was told should only be for 9mm. Well I'll look up the RRA buffer. Oh, well that might be a bit too much. It says the ST-9X weighs 8.5oz at their web site. The RRA and Colt 9mm buffers weigh 5.2 oz. If you were me and the buffers were the same length, I would try it just to see it it would work. It can't really hurt anything, just make the rifle short stroke. |

Does it matter if your AR has a carbine or mid-length gas system when using a 9mm buffer? I have a new 16" mid-length upper that I need a buffer for, would a 9mm buffer be a good choice for a 16" mid-length build with CTR stock and carbine buffer-spring? I use an A1 stock on one of my middys. The rifle buffer weighs about the same as the 9mm buffer. I have had no issues with the rifle so far. The 9mm buffer is an excellent choice IMHO. |

I'll try taking a look when I get home. If its the same size, I'll try it out. If it worke it will be awesome. But if it doesn't and is the same length, couldn't I just drill holes in it to lighten it up to make it work? Hope so. |

You could always sell it and get something else. |

BTW what would the worst that can happen to the 5.56 if the buffer was heavier (like the one I have). I'm assuming it might not cycle fully is the worst case since the buffer would require more energy to push it back. |

I wont go back far enough to cycle the bolt. If you havnt shot it yet I would be more than happy to exchange it for the ST-SST if you pay the difference bewteen the two. The ST-SST works great in ANY caliber, full-auto or semi-auto. -Tom |

That won't come in until the end of the month. I'll IM you.. |
