i picked up a xp100 in 221 fireball and tried today to scope it. my thought was to mount a scout rifle scope as i thought it would be better than a rifle scope, to close, or a handgun scope as really hard to get eye relive over 2x. the problem today is a locale gun shop had a weaver base i hate them as their is no adjustment for ring spacing and guess what the scout scope didnt fit fuck. it did how ever it looks like the eye relive
