This rifle scope is part of the mid-tier optics line called GLx. GLx brings premium technology and materials into an approachable price range.

The GLx 4-16x50mm rifle scope has a 4-16x magnification range, offering a massive field of view excellent for scanning and tracking movement, but improved medium-to-long range precision as well. For hunting, competition, or even just punching paper at the range, the combination of quality, features, and of course the Advanced Combined Sighting System (ACSS®) reticles is hard to beat.

This GLx 4-16x50mm rifle scope features 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 GLx is also home to one of the newest features. The 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 4-16x50mm GLx scope is equipped with the first focal plane ACSS® Apollo 6.5CM/.224V reticle. 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. The reticle has been tuned and optimized for 6.5 Creedmoor and .224 Valkyrie.

After doing countless amounts of research for a scope to put on my 6.5 CM, Glass clarity and color appear are excellent, slightly better than my Zeiss Conquest. Low light conditions = A. Eyebox forgiveness = A. Weight = A+. The Reticle is so clear and intuitive and works to 1000 yards = A+. Reticle Wind holds = A. The turrets are great and with a 20 MOA rail I get a full 2 Revolutions out of the elevation turret which is 20 MIL. The locking feature is very elegant and functional. Setting Zero Stop first time=C, Setting Zero stop after first time=A. Illumination clarity=A Brightness=A
<br>I would recommend this scope to anyone who wants a long range scope that can be used just as well as a hunting scope. At 23.5 Oz it has all of the bells and whistles with some Killer glass to go along with it. I genuinely enjoy shooting through this scope every time I use it.

Great scope full of great features


Really like this scope. Reticle is clear, illumination works very well. Time will tell but so far can't be beat especially at the price.

Excellent component

Added to a 6.5 CR Aero Precision based build. This optic is a delight to use. In combination with a canted mount, it did drop the objective 2 mils too low. Easily corrected. The GLX itself is a very versatile tool and I'm quite proud to have it. Additionally, the staff at PA continue to exceed expectations! I've relied on them for several years now and cannot envision that changing.

GLX Acss Apollo 6.5


The glass is extremely clear and crisp from 4 to 16 power. The reticle is nice and spot on. Turrets are firm with nice positive clicks and the zero stop works great. The illuminated reticle is very good also. There is no bleed through on the reticle from 1 all the way up to 10. Primary Arms hit a home run with this one!

Great optic!!


I put this on a Mark12 Mod O chambered in .224V and it is great. Clarity and reticle are great. Haven’t really used it a lot in low light conditions, but it is not better than my Zeiss 6-24x50, no way. Had 3 family members look through both at low light and all chose the Zeiss. All at 6 power. I am only talking about low light conditions. Everything else is on point. Reticle on PA optic, as far as tracking, is better than Zeiss. I got this optic and mount on sale and I could have bought 2 PA optics for one Zeiss. You do the math. PA all day. Have to get one in 6.5 G now. Hurry up and get some in stock!!!
