I didnt have any issues with the Mountain Tactical metal working without adjusting anything. I cranked these much tighter than can be done with the factory plastic. Before I got the metal for the first one I had to kinda fiddle with the factory plastic bottom metal tightening. I was able to tighten them up good, but in a certain sequence. Barely tighten both, then snug one, then the other. Or the plastic would shift enough to bind the magazine or not let it click in.
By the way, color patterns:
45% dark green, 30% black, 25% medium gray
280 Ai
45% olive, 30% black, 25% medium gray
