2ndAmendican, No progress yet. I bought a couple of the earlier Apex kits last year when they were on sale. I think they were @ $70 and came with 5 mags. The front trunion and rear threads were destroyed during de-mil.
This project isn't on the table yet, but I am doing some research. Looks like pyrotex and another guy on WG has the build figured out already and I'll probably go with a couple of Tony's receiver tubes.
There is a build kit and bolt conversion service being offered, but I'm sure I'm going to end up doing my own. I can't see putting nearly $700 into a semi-auto tube gun, which is what I would have in it if all of the parts and services available were used.
Leaning towards a 7.62 carbine. looks like I will probably buy a couple more Apex or Royal Tiger kits w intact ends. That will give me plenty of spare parts while doing the bolt conversion anyways.
I'll keep my progress posted here at Gunco. I think it's going to be a fun little build.
