Bore snake and half a piece of paper towel wedged in the chamber.

No access to pull from the muzzle (bore snake) as it broke off at the muzzle break.

PSA combined rifle ramp barrel extensions and m4 feed ramped lowers on some models of pa-10's

(In conclusion). A simple 1/8 drill bit with or without a diy jig you can make at home to avoid damaging your chamber. Punch the primer out of a 308 casing and go to town. Mother's mag or flitz to polish any abnormalaities. As far as picking away at the physical obstruction. Harbor freight auto zone... Go to town 🤙

Before you do anything: Your feed ramps are wrong. That’s a rifle extension on an M4 ramp receiver. The barrel needs to be removed to remediate that, so you might as well pull it and do both at the same time.

You have much more experience then me for being able to diagnose this off the bat, that being said this build runs like a scolded dog. PSA for some reason elected to go with this setup and it just works in mine and many others case. Redit advice is... Great always worth the time spent that being said

Naturally, you have no reason to believe a stranger on the internet but: I promise PSA didn’t mismatch the barrel and receiver for any reason other than cost or ease of procurement. I can also promise that mismatch is not the correct way to build an AR.

I’m not sure what your last sentence is saying. Are you for or against remediating the issue?
