I like the ACOG, but it looks a bit silly when attached that way...try moving the scope forward a bit, but keep the pin holding it to the rifle where it is. On another note, I love the stock on this thing.
This is a dream come true for me All of the times I have tried to make one of parts from other guns that ended up sucking So this is great! However, I think the scope should be different, IMO. I don't know why, but I just don't think this gun should have an ACOG scope.
Personally I'd prefer the ACOG scope as is, but if you were to scoot it up a little (because it looks most realistic in the pic) it wouldn't bother me. If you don't want the scope on the cut it off, it is easier to cut than add.
