The Nikon M-223 line are nice scopes for the money. Are you looking for more of a compact optic with minimal magnification since you have a more compact light weight rifle? (around x4-x6) The 1-4x20 pointblank would be nice. They have a new(er) one call the P223 also in a compact called the 3x32 BCD carbine I was pleased with the M223 3-12x42 nikoplex and will be ordering another one soon for my SPR.
P.S. How do you like that bushnell trophy? I was thinking of getting one for my 9mm.
