I didn’t put a lot of rounds with the suppressor and H0 buffer. It cycled fine but I can feel it cycling harder.
Without the suppressor I did have the gun fail to lock back on an empty mag a few times with the lighter A5H0 buffer. The only thing that concerned me is that it was 90+ degrees that day so in colder weather I don’t know how well it will function unsuppressed.
That's interesting. I ran Fiocchi 223 and Norma 223 and they locked back unsuppressed. Neither of those loading, esp the Fiocchi, are 5.56 pressure. I'm also running a standard carbine spring and H buffer, which I believe to be less forgiving than the A5 system. I wonder if several hundred rounds would wear in the new parts enough to change things.
It’s not really a home defense gun so I’m not that concerned about it. I’ll probably run it suppressed 90% of the time anyway.
Have the 12.5s started shipping yet?

Clint is there anything you can comment on regarding the report that Sniperfrog made on your 11.5” on the last page?
I really want to try your barrel mainly due to the profile and potential better accuracy, but if it’s on the ragged edge of reliability (when unsuppressed) then I’m not sure that’s something I can accept. Any thoughts?
I went out and shot 20 more rounds through mine. The last five rounds were PMC Bronze. I shot a mag of three rapid fire with a solid hold and a mag of two with a loose hold, everything locked back. Next time I go out, I'll take an H2 buffer, brand new spring, and a few types of ammo and do a little more playing with it, but I am not able to replicate sniperfrog's results. I do know different setups behave differently.
If you want to try a A5H4 I think you'll need to purchase that one specifically, as I think it is the only one with a drilled tungsten weight for the bias spring. When I eventually convert to A5 that's what I'll do, then use steel weights from old CAR buffers to downgrade as needed.
