The GLx4 rifle scopes redefine what can be accomplished when the latest optics technology is applied to meet the shooting challenges faced in real world situations.  New for this line is our enhanced locking turrets with return to zero, AutoLive motion sensing reticle illumination, and our hardened steel-on-steel adjustment system. The fantastically clear, low dispersion glass makes sure the optical system will impress even the harshest critics.

The GLx4 6-24x50mm rifle scope has a 4x magnification range, designed to help you locate, track and engage mid-range targets as well as reach out and engage targets at long to extremely long ranges. With the 6-24x50mm body, we're bringing you maximum usable magnification range in a package that's still convenient to mount on bolt action rifles. For hunting, competition, or even just punching paper at the range, the combination of quality, features, and of course our Advanced Combined Sighting System (ACSS®) reticles is hard to beat.

This GLx4 6-24x50mm rifle scope features our newly designed turrets, offering not just a new look but a host of incredible new features! 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 GLx4 is also home to one of our newest features. Our smooth magnification ring hosts an innovative swappable adjustment fin. The fin can be easily positioned anywhere around the magnification ring to meet the needs of the shooter. Optional upgrades and alternatives are on the way as well, allowing users to customize their scope to meet their needs.

This 6-24x50mm GLx4 scope is equipped with the first focal plane ACSS HUD DMR .308 reticle. Tuned specifically for popular .308 Winchester loads, but functional with some .223/5.56 and 6.5 Grendel loads as well, the ACSS HUD DMR .308 reticle offers a remarkable number of advanced features in a clean and intuitive design. Leads for moving targets out to a full 600 yards, wind leads, ranging, and bullet drop out to 1,000 yards, and even a MIL-ranging system are built in to the clean design. An illuminated horseshoe and center chevron allow for remarkably fast engagement of close-in targets. At any range, hits are intuitive without any need for math or digging through data books! Simply range, hold, and break the shot!

Note:While the ACSS HUD DMR .308 reticle is compatible with some .223 Rem and 5.56 NATO loadings, we recommend the dedicated ACSS-HUD-DMR-5.56 model for guns chambered in these calibers.

It's all about illumination.

by -

Been looking for a higher end scope and finally decided on this one since I have always been a fan of PA. The only thing that would make this scope awesome is if the whole reticle was illuminated. Only the horse shoe and chevron are illuminated and you can lose sight of the non illuminated parts on dark targets or shadows. The whole reticle is visible up to about 15X then you start losing the outside edges. The parallax dial has to be set at 80 for a 100 yard range for me. I haven't been able to check it at longer distances yet. This is some what forgivable since online research indicates that parallax dial markings are rarely correct and that some high end scopes don't even come with distance markings on their parallax dials. Other than the lack of full reticle illumination this is a beautiful scope.
