One of the best optics of its kind - Premier Reticles 3-15x50mm Heritage Light Tactical Rifle Scope - Illuminated Reticle

This is an amazing scope.
The diopter focus is adjusted by unscrewing the gear-looking ring at the rear of the scope and then you are able to move and adjust it (Which can be a downside because once you screw the ring back in, it somewhat 'customizes' the focus to that shooter's eye) The ocular glass is set into the scope a little so outside elements / smudges and whatnot have a harder time getting to it (Same with the objective end)
The magnification knob is pretty stiff and can be somewhat hard to turn, which is good or bad depending on how you look at it.
The 'clicks' on the turrets are VERY solid. It adjusts to ever .1 MOA however the scope is marked to every .2 (again, could be pro or con) and the elevation knob adjusts up to 22 mrad which is very nice.
One thing I really love about this scope is that the illumination knob is integrated into the parallax knob. It's like a ring that fits over it and you press it inward and then it pops out about 1/4 an inch and you can see the numbers on the illum setting and then push it back in.
The scope is easy to zero because you just make your adjustments and then flip the little 'tab' (Lever-lock toggle) on the corresponding turret and give it a few whirls to the left, TURN it back to zero (if you lift you will pull the internal 'teeth' out of alignment and then it's a pain..) and snug the tab back up and flip it over again. So much easier than messing with screws on a turret.
The scope is a little bulky (not a con in my book considering my next point..) but it's not as long and odd as most others I've seen.
The overall body of the scope is tough as nails. We haul them around and they take a little punishment and still perform flawlessly. My shooter was hitting targets with pinpoint accuracy at 743 meters.
I'd say if you want to hunt deer or something of the sort with it then probably stay within the 1000 meter range.
Whenever I build my bolt action you can bet this is what I'm putting on top of it!
Pros: Easy to zero/adjust, integrated features
Cons: The magnification ring can be difficult to turn (Could be pro or con)
