A new line of rifle scopes for shooters that want reliable optic without the bells and whistles (or the costs that come with them). The Monstrum Tactical SG3940-AO is a full-featured scope suitable for hunting, target shooting, or tactical use. The SG3940-AO weighs 1 lb 2 ounces. It has a 1 inch diameter tube and requires a mount with 1 inch diameter scope rings. The scope is 14 inches in total length. The outside diameter of the eyepiece is 44mm and the outside diameter of the objective lens is 50 mm. 

What is Parallax?

In terms of shooting, parallax refers to the alignment of the shooter’s eye in relation to the scope reticle and the target object. Unless properly focused, a shift in eye position will result in a shift in the position of the reticle relative to the target - the parallax effect. With a fixed objective lens scope (without AO), small shifts in eye position may result in imprecise targeting and less accurate shooting.

What is AO?
 
AO stands for adjustable objective (sometimes referred to as parallax adjustment).  An AO scope allows you to adjust the objective lens of the scope, bringing the target image into focus with the plane of the reticle.  When in focus with the plane of the reticle, the parallax effect is eliminated.  An AO scope allows you to 1) bring your targets into sharper focus 2) eliminate parallax and 3) gather ranging information about your target.
