This Primary Arms rifle scope is part of the SLx optics line. SLx optics have built a reputation for innovation, reliability, and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.

This Primary Arms SLx rifle scope has a 5-25x magnification range, the largest in the SLx line of optics and is designed for long range precision. The 56mm objective lens allows for greater light transmission resulting in an improved exit pupil and better clarity when dialed in at the highest magnification. 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 SLx 5-25x56mm rifle scope features the high quality 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 clicks. Externally, these 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 SLx is also features a smooth magnification ring with an integrated magnification throw lever for easily cycling through the full magnification range. Optional upgrades and alternatives are on the way as well, allowing users to customize their scope to meet their needs.

This 5-25x56mm SLx scope is equipped with the first focal plane ACSS Apollo 6.5CM 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.

Great scope

by -

Excellent scope, makes it easy to engage targets rapidly and varying distances

Great Optic


This scope is awesome. Full disclosure, I have 3 other PA scopes, & think highly of them all. I mounted this 5-25×56 on my Savage 110 tactical desert using the factory 20 moa pic rail, & Talley med 34mm rings. After boresighting, the 4th shot proved the tracking to be accurate & the rifle sighted in. 2 more sub-moa 3 shot groups using Winchester 129gr otm @100 yds & it's ready to go. The glass is very clear, no parallax issues when adjusted right, & the zero stop is simple enough. In my opinion it trumps my Vortex Viper, & equals my Nightforce. It is a bit heavy, but all things considered I believe this scope to be one of the best precision optics on the market, especially at this price point. Great job again PA!
