I've been looking through your links, and it appears that you describes to a T my exact problem in the "how it works", I still have the cases, and just as described in your link, there are also marks where the ejector is located on the bolt face. Sorry for not reading it through sooner, I was busy getting lot numbers and opening packs to find what color the dividers were. (No offense Snake RAH)
Now that I have a better idea of what's going on, what weight of H-buffer is most recommended to alleviate these problems? I see H (with one tungsten weight, I assume its the lightest) all the way to H-3 (with three weights of tungsten and a higher price tag, I assume its the heaviest) Which one would match the needs of someone who is running a semi-auto carbine?
Also, this is a side note, with my old upper ( BM, bought around 2004) my CAR buffer never had any marks on it at all, now, ever since I've had it on my newer upper (2005 BM) it's had scratch marks against the buffer face. I thought this might be important after reading this line of your description of overpowered rounds.
"Recoil will be higher than normal when the carrier is allowed to travel to the end of the buffer tube and bottom out swiftly against the end of the buffer tube. In normal operation, the buffer just kisses the end of the tube."
What might this mean? To be sure though, I'm picking up a new carbine spring with whatever H-Buffer I end up buying.
Thanks, you've been a great help, its nice to see someone with real knowledge helping someone like me get everything running smooth.![]()
