I need to talk to someone who speaks fluent 30 carbine

What's the topic...shooting, reloading, gunsmithing, history, values?

Ask, and ye shall be recieve volumes of information.

General Motors inland will not extract while firing. Cycle by hand and it will extract. I am looking hard at the extractor and spring. I completely fieldstripped and cleaned and oiled. Piston is very free. Am I headed in the right direction? Where do I get parts and tools ? It has an aftermarket montecarlo wood stock that I could easily be talked out of. Any info woul be greatly appreciated.

Is the Gas port clear and clean? Parts and tools check Brownells

Gas port and piston are Clean and good

does it cycle after firing? If so, I would suspect an broken extractor. I replaced two in the brief time I had a 30 Carbine.

Weak extractor spring. While your at it, go ahead and replace the extractor, extractor spring, ejector, and ejector spring. I would suggest that you spring for a bolt disassembly tool, because it's a royal pain in the arse to work with that tiny bolt without it.
