Swiss arms 4x32 fixed magnification scope. Great scope if you are keeping to one joule like me and dont do night games (not many night games near dublin ). Though, if your shooting beyond 328fps then I would go with a 3-9x40
anything from 3x magnification and up, preferably variable magnification.
Scope lens sizing preferably 40mm and up.
Avoid the "compact" scopes, as they tend to have crappy eye relief (Distance from eye to scope, where sighting picture is optimal)
I'm running a UTG/Leapers 4-16x44AO SWAT AccuShot Rifle Scope, EZ-TAP, Illuminated Mil-Dot Reticle, 1/4 MOA, 30mm Tube. Easy reset windage/elevation turrets, without need of tools.
(Tube diameter only allows for greater windage/elevation. Havent noticed improved sighting picture)
. It looks alot cheaper than the Leapers 3-9x40 parralax ao illuminated scope that i was about to order but i'm not sure if i should stick with the leapers as this seems a bit dodgy/bad quality. Worth buying? - as it is also a bigger lens diameter than the Leapers.
AIM 3-9x40 Dual Illuminated off Evike.com. Back light comes in blue and green colors. I don't think anyone needs more than a 40mm window honestly. The more window you have, the more of a chance at glare.
Not to hijack the thread or anything, but I have a 3-9 zoom scope that came with my used SR25 and I have no idea who it's made by. I know the flip-up sight covers say Butler creek and it has an eye relief of 4 inches.
Even though I haven't had experience with other scopes, this one seems to be pretty nice whoever it is made by.
*EDIT* Well, I didn't find the scope, but I did find out that the "butler creek" scope caps probably were put on seperatly, and that this isn't one of their scopes, but I really have no idea...
