Hi RWBlue01, well, I have a suggestion, send it to me, (the top half)and I'll fix and test it! The breechblock is broken at the extractor relief, and I would bet that the receiver is causing some restriction under firing that is delaying or buffering the toggle train under dynamic stress.... It will NEVER wear in! I have a ton of parts, and several test frames to work with... At the very least i can verify and correct if necessary, any problems with the top half?... If you wish to see my references, just search GT or GT Specialties on this forum?... I will do this service for reasonable cost for the parts only, no labor!... My email address is:
gctomeks@msn.com Let me know..... best, til....lat'r.....GT...
