Unfortunately, that gap between the larger brass lens retainer and the scope bell is present on all of the FM Elite scopes, which is strange because on his non-elite model he got that detail right. The brass should press flush against the steel of the scope bell, just like on the smaller front element. I adore FM's elite scope, but it does have a few flaws (this one being the most noticeable, and also frustrating for the above reasons).
Having to glue in the front smaller element is a little annoying, but not so bad imo because aesthetically it still looks correct when assembled, if you do a good, clean job gluing it.
It's also missing those small holes that are drilled through the steel at each end of the tube, underneath where the brass elements thread in.
Another one is the noticeable machine step in the larger bell. Once blued and weathered, that line always becomes more and more prominent, and it appears to be a very smooth transition with all of the real Hensoldts. I'm sure it could be removed cleanly with a lathe and some steel wool, but by hand I'm scared to tackle it for fear of messing up that subtle transition, keeping it uniform all the way around. This one is pretty dang nitpicky, though, I must admit.
Then there's the lack of serial number on the side of the windage base.
All of that said, the FM Elite is still my favorite Hensoldt replica, BY FAR! Sometimes the little, missed details just sting that much more when it's so near-perfect already.
