Got ya, I think the guy at the shop was referring to the upper which has no markings whatsoever. So basically I have some ones personal build. Thanks for the knowledge. I have owned 2 Ak47s but this is my first AR. Since my last post I have taken it out and shot it, and I have to say I am very pleased with the accuracy. I unloaded one 30rd mag. with no problem, the second and third mag would not cycle at all. These are all used steel mags that came with the gun. I figured that the problem was gunked up mags, so I took all of them apart, scrubbed, and oiled them (you would not believe the crap in those mags) . I have not test fired the AR since, but I am pretty confident I solved the problem. My AR. is basically a mill-spec AR-15 20" heavy barrel (I think this gun is heavier than my old MAK-90) I am planning to ditch the mill-spec stock and handguard the first chance I get to try and lighten the load a little. I think I am going with the M4 socom collapsible stock, a composite hand guard with rails, a green laser, and a flashlight attachment
