There was a guy in Tucson working on putting all that info together... and then VLTOR came along with the A5 stock and made all that shit obsolete.
The guys at Vltor were telling us how he was all bent because his work was down the drain.

Can anyone explain to me how one goes about selecting the proper Buffer weight for specfic combinations? According to the chart there are five (5) carbine buffers; 3.0 oz, 3.8 oz (H), 4.6 oz (H2), 5.4 oz (H3) & 6.5 oz (HSS).
Are there any "rules / theory" for selection? |

The heaviest that still cycles the weakest ammo you will use in your AR |

Soooooo, it's trial & error? One has to buy all the buffers and have them lying around? Isn't there a more scientific method than that?

I have seen a H3 run in a 14.5" middy and it shot real smooth even with weak ammo, but when the gun got dirty it just wouldn't cycle. |

So what would you use for a 16" 5.56 middy using MK262 (77's) and an 18" 6.8 SPC using 110's?

Help me out here guys. I'm not up on all the buffer talk. I know that the shorter tubes [used with collapsing stocks] are the rage, but is that because of having a collapsing option, or do the shorter tubes cycle the bolt quicker allowing for more rapid bursts [if one has a full auto weapon]?
I have a full length tube and am going to be going with a 16" mid length upper. If I keep the stock I have [YHM metal stock], would that cause a problem with a 16" middy? Currently running a rifle length upper. |

Currently running a rifle length upper. You should probably post pictures of the parts in their original configuration and how you're proposing to put them back together just in case we're missing something... If I'm reading right you're asking if your RIFLE LENGTH buffer and buffer tube will work properly with a midlength upper & gas system... and the answer is "yes." I had an Olympic midlength upper with an A2 style rifle stock / rifle length buffer tube and it worked fine. It's important to make sure you match the right buffer and tube combo, I don't believe that the type of upper & gas system matters particularly as long as your buffer tube & buffer are properly matched regardless if it's carbine or rifle length. Playing with buffer weights is more of a user experience/preference thing to deal with felt/perceived recoil and avoid bolt bouncing particularly in over-gassed carbine length systems. |

Yes, my current tube is the full length tube and the spring and buffer were used with a ~20" upper with rifle length gas system [of course]. The upper I'm looking to get is a mid length gas system in a 16" barrel upper. I'm hoping it works fine with this set up. I don't want to have to buy more parts for this project than I have to.

I remember the videos that one of the Arfcommers put out showing slo-mo shots of the different buffers. There was a fair amount of bolt bounce on most and the plain old H-buffer performed best. That is what I will put in my LW carbine. |

I just do what Sam does. H2 for 14.5" and under. Carbine buffer for 16" and over.
Middy is a bastard child so who knows.

I use a H3 buffer in my 14.5 midlength. I started with a standard buffer but was having issues with bolt bounce on full auto. The rifle was also cycling very quickly. I bought the H3 with the intention of removing weights one at a time until I had found a good solution, but after running it FA with Wolf without problems I left it with all of the tungsten weights in it.
