    Haha I was just reading that thread yesterday. Cant remember what I searched to find it.

    Best part, is he just clamped the gas block down with 0 hole on it. Basically showing that he had absolutely 0 idea how his gun worked, even in the most elementary fashion.

    No, I am not "too good" to answer your question. I saw your post and was surprised that someone would do what you did to your rifle. Sorry if you felt offended. That was not my intent.

    I think there is some confusion here. I just switched out a carbine for a mid length. These guys got off track and are now on another subject about a different guy.

    In my experience you don't need to change the buffer.

    Push the takedown pins out, pull carbine upper off, put mid-length upper on, push the pins back in. Add ammo, shoot.

    Even with low power .223 ammo?

    Got a chance to shoot it yet? It was a counter-intuitive answer (at least to me) to go to a slightly heavier buffer than a H-1 (the original buffer). But in this case, the bolt wasn't locking back as it was cycling too fast and skipping the catch with the 5.56 XM 193 Federal ammo. Slowing it down by using a heavier buffer allowed for the magazine to push the catch up sufficiently to allow the bolt to lock. A lighter buffer (car) only made the matter worse as it wouldn't lock back on any ammo, even the lower power 223. So after some more research, I went with the Spikes T-2 as it is lighter than an H-2, but heavier than a H-1. Reading numerous posts in a variety of forums showed that a large number of people were using the T-2 buffer with excellent results for their mid-lengths when using a large variety of different powered ammo.


    It now functions flawlessly with a wide range of brass case ammo makes in both 223 and 5.56.

    Nope, neither, just swap the uppers. You didn't mention the name of the manufacturer of the middy upper you planned on using, so I'll add this info. Some have been finicky operating properly when using different buffer weights. Some needed an H2 or even a H3 to run properly. I've had several middys (DD, Sabre Defense, LMT MRP) and used a carbine, H, H2 and an A2 buffer, without cycling issues, but settled on H buffers for my use across the board, but glad to find out my middies will operate with the buffers I have on hand. Some have also used the Vltor A5 buffer system. As IG stated, you should be fine with an H buffer and I concur, but then again, it may not.

    You forgot to add that all the tier 1 operators are doing this now with their super secret DPMS rifles
