Hi Jim, I had one on a 450/400 #1. I preferred the Skinner. I used the Skinner as a "ghost ring" and it worked quite well. The NECG has, for lack of a better term, wings on the sides of the aperture that block out areas left and right.
The advantage of the NECG is that it can be mounted and removed easily if you want to use a scope, where the Skinner actually mounts through the quarter rib. Also, I should point out that I used a NECG slightly oversized white bead front sight in conjunction with the Skinner. Hope this helps. Terry
