Was wondering if someone could identify my issue.

Been trying to tune this with an ODB suppressor, also partisan FRT, H3 weight, carbine spring(i do have a yellow and a white hot from springco). Its having bolt bounce issues, Ive done a few parts swapping but everytime I shoot this yellow grit shows up, I think its clogging the bolt and affecting the bolt travel.

I fully disassemble, clean bolt, install sprinco extractor spring, clean upper, clean lower.

I got to shoot and subs cycle perfectly for the first 3-5rounds. Then the yellow grit and back to non feeds or light primer strikes.

Any insights? TIA
