There's at least two different blasters featured in the pics on that article. One clean, one weathered.
So let's see, off the top of my head;
Unaccurized Denix, which means
-soft details all over
-Denix logo still present
-missing lines from the bottom of the mag
-missing extractor from the bolt
-solid cast safety switch
-weird nubs on the rear sight housing that aren't supposed to be there
-In one of the pictures the lanyard loop is present , in others it's gone. Far as I remember, none of the screen-used blasters had the ring
Things that were right;
-Flat bottom bull barrel
-Front sight
-Flash hider
-Scope&mount
-grill
So, basically with a better base gun or some elbow grease that might just fit the bill. As is it's a nice display piece, but far from accurate.
