thanks folks on info too. i was out hunting last night, just before dark. i was practicing holding gun on stumps and pine cones etc from trees. here is way i feel you have to use the V-PEEP from RMC . i was not happy that the rear sight got blurry trying to line up front. what i did not realize is ,i dont need to concentrate on rear sight. when you see the front dot, which that is all you should be looking at , its IN THE RING of the rear sight its was great after that. i had 2 doe come out about 40 yards and i pulled right up and front sight was there and clear. i forgot all about rear sight. if you aim like this, that V-PEEP is great.i shot peep sights all my life until i went to scope and i never looked at rear ring on deer.why i forgot that on this V-PEEP, I dont know.take care.also i like the green fiber optic over red one on front sight of the V-PEEP.
