IMHO, the NEWER...not the older...BSA Catseye are worth taking a look at. Can't argue with the "cheap" Bushnells...many of my rifle bores are guided by them. One of my local gunshops had a huge sale and offered 3x9x40 Banners with adjustable eyepiece for$40...bought 3 of them! They don't belong on a heavy banger tho....again, IMHO.
