[lil tec-22]

Hi there, iv recently got my hands on a intratec 22 and it has been one prob after another. well really its been the same prob everytime heres the deal. I can only fire 1 shot at a time. it wouldnt expel the spent shell. so i bought a volquertsen extractor. now it either ejects fine and throws a rnd in the chamber but doest reset the trigger. or the shell gets smashed like the bolt didnt go far enough back for it to exit. or it jus fires. the bolt doesnt move...

so i started my process of elimination.. I only fire stingers and thunderbolts. (still doesnt cycle. I cleaned it very well.

while cleaning the bolt on the underside rear where it makes contact with the hammer loooks like its been shaved.. Could tht be a groove formed from normal wear and tear? can a bolt go bad? iv looked at new ones online and they r perfectly rectangle.

please help
