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 Athena BPR MIL reticle, the world’s most precise reticle for use at extremely long ranges beyond 1,000 yards. With a holdover grid encompassing a full 50 MIL of drop, it’s easy to not just find the perfect hold over, but quickly recover and correct a missed shot by spotting the impact on the grid and adjusting your aim accordingly. Fine aiming dots are displayed in 1 MIL increments, making ranging and hold overs a breeze. When the reticle is tied in with a ballistic calculator, even advanced calculations like spin drift and Coriolis effect can be accounted for and applied to a firing solution without ever touching a turret! For those who prefer to count their clicks, the 0.1 MIL adjustments match perfectly with the MIL based reticle. This handy reticle is compatible with any caliber!

PA Delivers!


I've purchased this scope and it's currently being shipped. I've made a lot of purchases with PA. I've bought 98% of the parts from them and they have been my primary source for years. It would take me 2 weeks of 8 hour days to write the reviews for the products I've purchased through them. This is my 2nd or 3rd PA scope since I've been a customer. I could not pass up trying this scope out! I bought a Vortex 3-18 x 44 two weeks ago prior to learning of this scope. It's also a Mil with the BDC tree reticle, however, the reticle at the center is just too busy in that scope and I'm partial to Mil scopes. So when I saw this reticle and the thought process of the layout, I had to jump on it! I haven't mounted the Vortex scope because I have already concluded this PA reticle is better for my philosophy an intended use and, I'll most likely be sending it back.
Thanks PA for providing such excellent products, prices, and being the best source online!
