I don't have any pictures, sorry, I'll see what I can do.
I probably don't know the right term but on the lower where the buffer tube screws in, the top shelf was too high and hit the charging handle. I probably cut at least two thousands off to get the charging handle to move freely.
I bought the complete PSA PA10 lower build kit for my TM stripped lower. The supplied take down pin and the pivot pin are AR15 items not the longer DPMS pins and the bolt catch is the AR15 style.
After careful examining the upper I found the bolt sits closer to the lower with this upper and when I put the magazine in it hung up on the mag lips and the reason the bolt catch doesn't work is that when you close up the gun the upper has a wider section there that pushes out the top of the bolt lock/release out to hold it in the locked position. The parts kit came with the roll pin to pin the catch/release on the outside of the lower like a AR15 not the recessed one with a screw pin like on the DPMS style. I have both types of guns here so I can compare.
