The suppressor increases the gas pressure and volume, there is not a blowback effect in the bolt cycle.
Your suppressor effectively lengthens the barrel and causes more gas dell time on your pressure chamber in your bolt carrier.
Have you looked into the suppressor bolts now available? They have a suppressor/no suppressor adjustment and reportedly work well.
Most semi-auto guns run well on one type of ammo. They can be set up for whatever you want, but trying to get one to run on everything is a lesson in frustration. Set the gun up for suppressor only use is optimum .
The Gen II recon uses a proprietary bolt and carrier. I don’t know that I want to replace it or if I even could given that there’s no such thing as a mil spec AR10. If we were talking about a mil spec AR-15, I would consider that option. I’ll see if the AGB solves my problem which I am pretty confident is overgassing secondary to the suppressor. I like the idea of being able to just switch back and forth between settings for suppressed and unsuppressed. If it doesn’t work I’ll start messing with buffers. I think it just needs retuned for the suppressor.
