i have about 15 red dot scopes, the aimpoint comp is definatly at the top !
i have 4, the redfield esd are on sale at sportsmans guide . 4m0a in silver
$80.00 the 4 different dot size model is $116.00 at byers club price a real bargin i have 3 of that model i would stick with the 4 moa only because you will have more problems with 4 reticles, the redfied is close to the aimpoint but the length is a little longer, i personaly would bye the docter sight ,something like a tasco optima but vastley superior .nataches shooter supply wants $266.00 + $39.99 for a mount which is a good price.
i have a new trupoint open red dot sight that is simular to a docter sight but with a built in weaver mount . i bought 3 if you want one you can have it for $179.00 wich is dealer cost, i had to bye 3 to get dealer price .+ shipping and ins if desired around $10.00 if intrested or you have any more questions leve a mesage on this fourm
