This GLx 3-18x44 rifle scope features extended range patented turrets with a full 180 MOA of elevation adjustment! Each movement of the turret will provide a crisp, audible, and tactile 0.1 MIL click that will never wear out thanks to the tough steel-on-steel construction! Externally, these locking turrets feature a high speed return to zero, ensuring that once your zero is set you won't have to worry about bumps or the environment making unintended changes to your turrets. The return to zero feature allows shooters to rapidly return to their elevation to 'Zero' after dialing out for long-range engagements without having to keep track of the adjustments you made to get out there in the first place. Not sure where you left your elevation the last time you were at the range? Not only can you simply return your scope to your set Zero, the elevation turret features elevation rotation indicators to get you back on track at a glance.

The smooth magnification ring comes with a magnification lever installed. This lever features the dovetail attachment style allowing you to swap to the folding UML magnification lever if you choose.  Optional upgrades and alternatives are on the way as well, allowing users to customize their scope to meet their needs.

This 3-18x44mm GLx scope is equipped with the first focal plane ACSS APOLLO .308/6.5 Grendel reticle, simply the ultimate option for .308 Winchester or 6.5 Grendel shooters available. Simply sight in at 100 yards and you are ready to engage at any range out to 1,000 yards with crosswinds up to 20 mph, all without requiring any math or touching a single turret. Combine the built-in range estimation and hold overs with an infinitely precise chevron tip aiming point and .2 MIL crosshair subtensions, and you have a firing solution at any distance.
