| Is it a good idea to run an H2 or H3 buffer on a 16" AR with a suppressor? |
|
Carbines (10.5"-16") have higher bolt failures than rifles (20"). Which is why I use heavier buffers in them. Its the higher pressure and cyclic rate that causes the problems. Adding a suppressor magnifies the problem. I was running a Enidine in my wifes Noveske but she had difficulty lock the bolt the the rear (manually) and she liked the H3 better (no harder to lock back than a regular CAR buffer). Read what Coldblue (LtCol Lutz) says here. www.ar15.com/forums/topic.html?b=3&f=12&t=288630&page=3

so are you saying you put a different buffer in it when she shoots, or that it's hers, but you do all the "running" of it?
It's her gun and I'm her builder & armorer. The H3 stays in it full time. She couldn't lock it back because the Enidines last 1/2" rearward travel to lock it back is too strong for her. We didn't buy it as a complete rifle. It's a RRA lower w/Magpul stock that I built up and bought the Noveske Afghan upper. This is one of her many guns. Actually the upper is on the way back to us. Randall at www.ar15barrels.com fixed it (shorted recrowned and perm. mounted a AAC SOCOM FS'r to it. We changed from a Gemtech can to a AAC M4-2000. TTI F'd up the threads removing the Gemtech M4-96 mount. Here's TTIs **CK UP. They actually tried to tell me it was made that way.  And they couldn't remove the Larue rail to shorten and rethread. Me thinks they applied way too much heat to remove the Rocksetted M4-96 FS'er. This is what it looked like before. Randall had to cut it down to about 13.5" or so. I just got the email saying it's on the way back and I can't wait to see how it's come out.    UPDATE: This is what it looks like now after Randall Rausch worked his magic. Door to door in less than 2 weeks!

What's the problem? I'm gotm4's wife. I've been shooting for 23 years. He has many ARs, and so do I. He's not some spineless man who has to "justify" spending money on guns like so many around here. If I hadn't met and married him, I would be building my own guns, but he's a better armorer than I am. I wanted a very accurate and reliable AR, so he suggested Noveske. This rifle would shoot .43" groups at 100 meters, before Randall worked on it. After Randall worked on it, it should be capable of the same or better. |
That's ugly. Is it possible a high round count contributed to metal erosion at the end of the barrel, or is that "tool' marks? |
Upper has about 700 rounds through it. No where near HIGH IMHO. The Rocksett I used melts at 1800 degrees so that means TTi had to get it at least that high, probably even higher to bend the whole threaded portion. It's a good thing that Randall shortened it. It was probably very brittle. |

Bradd, I'm running an H2 buffer on my M4 (14.5", full-auto) using the M4-2000 and sometimes the SCAR-SD. No problems. I'm also running the SOPMOD flash suppressor, which adds less length than the Phantom mount. So that 14.5" barrel is less than 16" with the SOPMOD. I'm gonna hit Madison this Saturday if you want to come play. I can't do the FOP shoot. See ya. Mark |
