doniva,
Curious about your request for a mil-dot scope in power you wanted, with AO. I checked numerous brands of scopes on SWFA site and perused what's available. Assumed you wanted something lower priced than a Leopold.
As you already know, not much out there with what you want.
Did find one though, which happens to be a tactical Mil Dot scope I have and it is on a 6.5 Swede sporter rifle. Found mine as an open box special for 1/2 the price of anyone else selling it on internet. Thought I'd give it a try.
Scope has been OK for me and has had a fair number of 6.5X55 rounds fired with it at a range I'm a member. Optics nothing to rave about, but decent. Guys that want a light gathering scope that performs like a night vision scope would hate it though. Side Focus (AO) on it seems a little stiff compared to SF on several other brand scopes I have with that feature. Anyway, its a Barska. Yep, a brand not highly regarded by many. Barska not a brand I normally suggest to buy, but have several centerfire rifles with brand and I've had no problems with them.
Anyway, here is SWFA web page....see the 3-12X40 tactical.
