I have a great Yugo underfolder. Standard Century model parkerized with black polymer furniture, Red Star Arms retainer plate, slightly corroded piston(as many Yugo's have), slant muzzle brake. I've put around 300 rounds through it with no problems. Great gun overall. Looking to trade for another AK-47(WASR, etc.) but with a standard combloc metal wire side-folding stock. Just want something that runs fine with no issues, no canted sights, detachable non-welded muzzle brake/flash hider and minimal mag wobble, prefer Romy wood pistol-style foregrip, but not a big deal if plain wood or polymer.
