Without gunsmithing I'd first try an XH buffer and an LMT enhanced carrier. You're going to spend some money.
If you want to keep your present
overall system length (with the suppressor you already own) you might try a mid-length gas barrel (port pressure will be lower than with a carbine-length, but
overall system pressure time until un-corking is the same). It'll help, but won't
solve your pressure-time curve issue.
When you clean the bolt keep an eye open for flame cutting around the primer pocket radius on your bolt face:

LIKE suppressed ARs, and I like the
idea and concept behind them. The mechanics are a challenge, as the rifle-carbine were not originally
designed for them.
I do have EBCGs in both of my 10.5s so I could easily swap a carrier in to try for a bit. I forgot to check the buffer too but I have one of every weight for spares for the A5 so I could easily drop to A5H0. At this point though I’ll probably keep as is and put some more rounds through it then document the issues better. I have an 11.5 Super Duty and a BCM upper that I need to pour rounds through also so it may just be an expensive trip to the range.
Worst case, I’ll give Criterion a shot at fixing it, otherwise maybe I’ll try out the FCD barrel and see how long a SS lasts. At least I trust their CS.

Not that it tells you much but it is a data point, especially if its running hot it should run. Unless that brass just hates that W chamber.

I was taking a private precision course so all single shots really, I tend to notice recoil issues more in a string of fire. That said, the recoil didn’t even register until I took the can off. As soon as I did that, I remember being a bit surprised at how much the felt recoil increased.
I may be able to shoot it this weekend, still going back and forth on whether I should clean it first or not. FWIW, it’s better than how most of my ARs normally look. I rarely clean them and usually it’s a non-issue. The can is still a bit new though and this is my first .233 Wylde chamber, plus the only other time I’ve had popped primers was when I was shooting known shit ammo (Freedom Reman) which all adds to why I was stumped.
