More messing around this evening has resulted in nothing but issues. This receiver set is terrible:
- The trigger and sear holes are good, the hammer hole is slightly off...as in not even aligned.
- The slot that houses the bolt catch and firing pin unit is off enough that the unit doesn't even fit. If that wasn't enough, none of the 4 bolt catches I have even fit by themselves.
- The threading on the upper is somewhere between Metric and Imperial. How this was accomplished I have no idea... But I have known Metric and Imperial threaded delta ring assemblies and neither one thread.
- Did I mention the buffer tube? I think I have...
Plan A is very quickly turning into a quagmire. I'm more than likely going to cut my losses before they pile up even more and cause me to throw what is left off of my 10th floor balcony to see exactly how high it will bounce off the street below.
Plan B, while not optimal will hopefully
prove to be somewhat more fruitful.
Messing with the magazines doesn't give me too much hope. 2 hold gas as they should. 3 leak from the fill valve, 3 more leak from the lip seal and 1 vents gas out of every little hole there is. Luckily I do have spare fill valves I can try. Perhaps these will remedy the 3 that leak from there. Whatever the case, I don't plan on fielding this anytime soon, if ever. It will be a nice little training aid though.
Then there leaves Plan C.... This...this may actually work out. I'll have to see what comes of my efforts tomorrow with everything else.
