| Buffers are sized to your gas system, if you are overgased, how much so, etc. What someone else is running on a different rifle is meaningless. Most commercial rifles are overgassed. I don't know about S&W. If your "into" ARs you should probably have a standard buffer, H, H2 or Spikes, and H3 or 9mm on hand. What you do is run the heaviest your rifle will function with. If you have a barrel that that has a "smallish" has port, like Rainier, BCM, LMT, etc you may find that is a H or H2, and to run wolf or low powered 223 you have to run a standard car buffer, or may not even get that ammo to run AT ALL. If you have a barrel that has a larger gas port, leaning toward "overgassed" like a Colt and most commercial ARs you may be able to run a H3/9mm buffer and run upto a H or H2 with low powered 223. |
| My S&W has run well with both the stock buffer and the ST-T2, but these days I just run the standard one, it works just fine and gives me the most flexibility in terms of ammo. If I plan to run hot stuff I might switch out, but generally I leave the original in. |

its a 16in i was just wondering if it would really help the gun in any way Does the rifle run now? If yes then why are you fixing/changing something that is not broken?  Because isn't that what we do here? Mine worked fine stoxk but I wanted not needed to try and reduce some recoil impulse and create a more reliable rifle,so I changed from carbine to a stt2 buffer and fa bcg not because I needed to but because I could |

What is wrong with the factory buffer? Does the rifle not function? Exactly. There is no "UPGRADE". Get the right buffer for the gun. Maybe it is an H buffer. Don't buy that silly Spikes thing. It doesn't work as well as a buffer with actual floating weights. |

i'm thing of upgrading my buffer i have a s&w mp15t. i believe it has a standard buffer, which would be the best buy to upgrade the rifle I had tried all the carbine buffers from the lightest standard all the way up to the heaviest 9mm with good ammo and mags, they all worked (YMMV). However different users have different preferences, and if you ask the members here you will get different answers and will include from the lightest to the heaviest buffers with some custom buffers in there too. I've got two carbine gas system with 16" barrels, a Colt with a heavy barrel and a LMT with a M4 government profile barrel, both of them have H buffers, standard carbine recoil springs, full auto carriers, and BCM extractor spring uprade kits, I'm very satisfied with them. |

To soften the recoil impulse to allow for faster follow on shots. The M&P15 is particularly harsh as far as carbine AR15's go (at least mine is), due to a larger than usual gas port. By dropping in an extra power spring and/or heavier buffer, it can make the rifle feel nicer to shoot. If you are just putzing around at a bench, it is no big deal. If you are trying to shoot a carbine competition or participate in any other practical shooting, it can help. I run a H2 buffer plus Sprinco extra power spring in my M&P15. The improvement is noticable and it remains 100% reliable even with the shittest of ammo (Tula). |

Don't buy that silly Spikes thing. It doesn't work as well as a buffer with actual floating weights. Care to back that up with reliable references? And I don't mean that video of FA fire which does not apply to 99% of the members here and even there it worked as well as most. |

87GN's video of Semi auto fire illustrates this. I haven't seen any Full auto videos.
What you have with the T2 is a guy who took some cheap tungsten powder... probably much cheaper than forming actual weights... and sells them to the poser market who thinks a silent buffer is an improvement. I mean.. God bless the guy at Spikes... it's America after all and a free market. But I've yet to come across anyone knowledgeable who endorses the Powder system as an improvement over actual floating weights. |

And I don't mean that video of FA fire which does not apply to 99% of the members here and even there it worked as well as most. my biggest complaint with the T2 is it's loaded by VOLUME, not weight... i've read reports of T2 buffers weighing as little as 4oz... from spike's website: - cuts down on noisy weights (subjective, based on user hearing) - makes for a very smooth cycling rifle (subjective, based on user feel) - It eliminates the chance of bolt bounce and muzzle rise in full-auto. (proven false, but as you said doesn't apply to 99% of users here, also using the word "ELIMINATES" screams snake oil to me) - cuts down on felt recoil (subjective, based on user feel) so exactly what does this thing do that makes it worth $30 for a SEMI AUTO AR15? weighs somewhere between a carbine buffer and an H2 buffer depending on how much HDTP they can stuff in it, and makes a bunch of subjective claims that can't be quantified and proven using scientific method? |

I would only buy buffers with weights inside. |

I guess I'm a poser then. All I know is I was having ejection timing problems on my .500 Phantom with it ejecting to 1:00 and often failed to clear the port with one load and ejecting to 4:00 with another load. I went round and round trying to adjust the timing with adjustable gas blocks, different powders... but what would work OK with one load would give erratic ejection with another. Turn the gas down to work with the 1:00 ejection and it did not give enough gas to work with the 4:00 ejection, and with the configuration of the rifle the adjustable gas block meant having to remove the forend to adjust it or drill holes in the forend, and that was not going to happen. What finally brought it around was using HD tungsten powder in the buffer and getting the buffer weight tweaked just right so that I got good ejection on all loads. I got the 1:00 ejection moved to 2:30-3:00 and the 4:00 ejection moved to around 4:30 and now both loads run 100%.
And yes, I had run the range of adjusting the number of weights in the buffer from none to all but there was no way to increase the weight above stock unless I replaced the weights with tungsten weights but that still would not allow fine adjustments. The powder did the trick allowing me to add weight a tenth ounce at a time to the buffer which brought things around. And just as I figured, no real documentation of how tungsten powder actually harms anything, just prejudice against something new and not tried. And I'm the poser. |
