The receivers finally came today from Joeken from the group buy. I managed to put most of this together in the last couple of hours except for the fire control group and final installation of the buttstock. It's a Polish kit from Global on a Vulcan receiver. I'm using button head machine screws for my first build. The front trunion holes lined up perfectly and it only took about a half hour to drill/tap and install the trunion. The barrel I pressed in with my good old BFH, a 55 lb anvil and a couple of peices of wood. Didn't even scratch the finish. The barrel pin installation went similarly well. The rear fixed stock trunion is going to be a problem since the holes don't seem to line up very well. I should be able to egg them out a little for a good fit though.
The only problem that I'm having so far is that the bottom of the bolt catches on the top of the magazine. I've tried all six of my mags and it's an identical problem. I'm not sure whether to take off a couple thousandths from my bolt or to try taking off a little bit of the mag catch lever. Anyone have a similar problem?
I think on my second build I'll try Hotbarrel's bucking bar and install some rivets. Probably make that one into a folder.
Here's a link to a pic of my gun so far.
