Sounds like the bolt is not going fully into battery; or it's unlocking early (only a "maybe"). Neither of those are good.
And to reiterate, that's factory repair territory.
I contacted AO today and they said the warranty is only a year from original purchase date but will do a free inspection. After inspection they will let me know what the cost of repairs will be. So that’s probably my next step. I got the bolt tool today so I probably will take that apart and clean it good.
I was working on the piston last night with CLP and a 308 case. I was able to move it slightly side to side, there was a bunch of greenish gray junk dripping out as it moved the little it did. Still no in and out movement though
