I spent right at $450 alltogether, not counting scope, mount, and new Dremel bit for the spot welds
Rifle - $310 shipped, FFL, tax (from CDNN)
RedStar FCG + Retention Plate - $75 shipped (EE)
Choate Stock Set - $60 shipped (Ulitmak)
8-32 stainless bolts & nuts - $1.85 (Home Depot)
That should get me down to 10 foreign parts by my count. You could do this for under $400 if you use a GT FCG and don't live in Texas (tax on rifle).
I haven't refinished the bottom of the receiver yet, however. I'm just going to paint it. I used some Tester's enamel to touch up a scratch, and it matched pretty well. The momentum forced me to complete the assembly without painting the bottom.
As for the trigger guard, I cut off the end of the tab that held the bottom stock screw, turned it around, and pressed the remanents of that tab under the mag catch. I then used wire ties and a large C-clamp to squeeze the new rear of the trigger guard into position so I could put the bolt through the receiver and add the nut. I used blue Loctite on the threads of the nut to keep it from backing out any time soon. The fact that the trigger guard has to be compressed over 1/4" makes it very solid.
Finally, it is an OKO model W that I also got off the EE. It's a neat little scope, but I'm definately going to add the Choate cheek rest in the near future. I'm also already thinking I might to replace the OKO with a 6x24 PSOP. Maybe coupled with a rear peep sight for close-in work. We'll see. It's staying this way for the time being.
I highly recommend the RSA retention plate. The BHO spring was bad enough to put back in, so I cannot imagine reusing the shephard's crook. Blah. That thing is a royal PITA to remove.
Unfortunately, family obligations will keep me from testing her out until Monday or so.
