The second issue was during the several hundred rounds fired the safe/fire selector would ever so often move down enough to keep the gun from firing (shooting may two and three round bursts) until I pushed the selector back up a little.
Checked and the "spring" (aka pivot plate) appears in the slot however the selector for safe/fire is not that firmly in the fire posistion. While waiting on the paper work the SOT and I will be talking everything apart to check (he knows his way around a TSMG a little bit, owning several and having built a receiver from scratch on a Form 1 in the good old days), but would like to check with the knowledge base hear for my own educiation on what to watch for when trouble shooting.
Assume the tree areas to check are:
1:The safe/fire slector where it contacts the pivoit plate and any of the internal firecontrol parts (assume there is a ramp/detent to provide the force to keep the slector on fire).
2: The force of the external "spring" (aka piviot plate) - any field checks on the force of the flat spring that contacts the selector etc.?
3:What ever internal fire control surfaces contacts the selector
4: Everything else that I do not know enough about (probable the best answer for the typical question on repairs is "if you do not know than send to the experts such as P.K. ....
Thanks again for everyone inputs and ideas.
