Looking to get a peep sight and globe front sight for my 40X rim fire. Im not looking for original equipment unless they preform as good or better than something new from say Lyman. Ive got the front sight dovetail to clamp on the front sight and the two screw rear mount on the side of the receiver. Looking for elevation and windage adjustment rear. Whats everybody running? Anything to stay away from? Thanks in advance for your suggestions, opinions and links to other threads discussing this
