Re: NIGHTFORCE EYE PIECE / POWER RING
Scopecoat makes oversized neoprene pull-overs that fit even if you have the extension on the front. Best protection for your scope I have found. I agree with the guys, you will probably not change the magnification much if at all for most of your shooting. I would forget about it and enjoy your wonderful scope - you got one of the nicest scopes out there.
By the way, I find that #18 Butler Creek flip-ups fit the eyepiece very nicely, some guys use #17's but I have not tried them. I just use the Butlers to keep my own greasy thumb-prints off the eyepiece.
