A coupla quick response - Z_Recto is a guy who sells on another well-known AK board, infamous for some of the behavior of its members. He restores/modifies imported wood to a very Soviet look, and also makes his own (US-made, 922 compliant) furniture -what you saw above, mock-Hungarian wood, etc. Stamps it "us" and does great work (as you can see).
Mag - yeah, I actually like East German mags the best, and need to get a couple of those really black Bulgarian ones for my SA93 buildup. I got these chicom mags in a deal - was walking past someone's office where I worked a few years ago and overheard "seven sixty two by thirty-nine" and popped in later to talk to my new gun nut co-worker. He had just sold his AK and had about a case of ammo and four mags, which I bought at fire-sale rates ($4 a mag, and probably 1/2 off the ammo actual cost to him). So they are my range mags.
They do seem to fit a little tight, sometimes tough getting the mag release free/unlatched - a problem I did not have with the DDR mags. What should I sand/dremel? Note that this rifle is an INTRAC Maadi import, not a MISR, so it was originally set up for the standard (30-rd) cap mags - basically the only difference between it and today's SAR-1, as imported ,was tack welded muzzle nut and butthole stock.
And yeah, that's my hairy foot ;)
