A buddy of mine has a palmetto state armory pa 10 that he is having ejection issues with while running a can. The spent casing is ending up jammed back into the breach in the opposite direction. It wasn't doing it with out the can so I was figuring it was a overgas issue with all the extra back pressure. I have no experience with suppressors so that's why I'm seeking your guys help. I was figuring a adjustable gas block and maybe a heavier buffer may help? I figured I would ask first before I gave him bad advice. Thanks

Yes she's over gassed the bolt is coming back so quickly the spent case is detaching from the extractor and laying on top of the next round in the Mag when the bolt comes forward you get your FTE... Get a AGB and a Heavy Buffer.

I had similar issues with my build. Get this buffer (assuming it is a carbine length buffer tune).

It will make the recoil impulse much more gentle. Then get an adjustable gas block. There are a lot out there, but I am partial to Odin Works products. If he tunes the gas block to lock the BCG back without a suppressor, he shouldn't have any problems when he throws it on. It will be more gassed and the brass ejection pattern will probably change as a result, but he won't have the BCG velocity going out of control anymore and spinning cases.

The PSA PA10 GenII 's are certainly over gassed. My middie was down right mean while cycling in its OEM configuration.
I added a SLR adjustable gas block, a rifle length stock and buffer system w/ a KAK 9.3oz .308 buffer and a Tubbs .308 Flatwire.... calmed it waaaay down.
I can now stay on target far easier at the bench.... on a side note, have your friend check his gas tube to barrel nut contact, mine was making complete contact and was being forced upward... I will send an IM with a link to my complete ( and very through report with a lot of accuracy tests.... etc, you'll see... ) of my PSA .308 .
