I had the crazy idea to do a RPK look with this but I think I'm going to enjoy it for what it is, just a 20" ak type rifle. It has a slant brake on it now but I may go with a muzzle nut. The plunger was frozen and took the better part of a day to get it out and functioning, it works now but it has a weak spring and I may have to change that out someday. I put an East German RPK sight on it, I figured that either an EG or Romanian would work for looks. Compliance parts right now are slant brake, fcg, pg, and floorplate. I am getting a non-glossy finish black Egyptian pg from Steelcore and I'll change the gas piston for a US one when I put that pg on. Then it can share all the US floorplated Egyptian mags I have for my ARM. It's a hassle but worth it to be able to keep the furniture original.
Anyway here are some more pictures of the RPM and ARM together, before and afters and all that: http://picasaweb.google.com/philipgrasmussen/ArmRpm
