Is the Primary Arms SLx 1-10×28 on your radar for your rifle? Let’s dive deep into a comprehensive review to determine if it’s the right fit for you!
Primary Arms makes many great scope options, so how do you know which one is right for you? In this Primary Arms SLx 1-10 review, I’ll dive into this scope to help you determine the right scope for your needs.
Primary Arms SLx 1-10×28 Scope
When considering what magnification you want for your LPVO, you’ll want to ensure you get enough to accomplish your end goal.
When you’re looking for the perfect scope for your AR-10 or your bolt gun, you should want the highest level of magnification you can get with the least amount of target distortion, and I think this is where the Primary Arms SLX 1-10×28 shines.
The 1-10×28 specifications are pretty impressive, considering the $449.99 price point. The magnification and clarity of the optic are extremely solid.

When I first picked up the SLx 1-10x, I was impressed by the weight and overall feel of quality.
Based on the overall feel, I felt like I was holding a $700+ LPVO. A glance through the unmounted glass, the reticle was crisp and clear.
I was inside, so I didn’t get a good sight picture then, but a good test wouldn’t happen until it was weapon mounted anyway.
The exterior construction of this LPVO is all metal, including the turret caps. The scope adjustment ring and the full body of the optic is metal. While Primary Arms doesn’t tell you exactly what metal this optic is made of, it’s safe to say it’s aluminum and 7075 or 6065.
Most reviewers don’t harp on the weight of LPVO reviews, and I won’t. Typically, guns you want to throw an LPVO on aren’t built to be extremely lightweight.
However, if you are, this optic clocks in at 19.1 oz without a mount. What mount you put on this scope will matter more than the optic itself.
Since it’s only 19.1 ounces, throwing this on top of any rifle won’t be a big deal.
The reticle choice will change much on this scope, depending on what you want to do with it.
The reticle I have on my SLx 1-10 is the ACSS Griffin M10S Reticle. A lot is going on with this reticle, but it gives you plenty of flexibility for windage and elevation.
I’m a huge fan of the optics that use the chevron and while this one has the half-circle chevron and not just the plain chevron, I still like it a lot. It illuminates and helps me get on target easily and quickly.
The primary arms 1-10 ACSS reticle provides plenty of on-the-fly adjustment options.
There are two parts of the reticle that illuminate: the half circle and the chevron, the two most important parts. That makes this a partial illumination reticle.
There are 7 regular brightness settings and two settings labeled with a “D” for daytime.
The Primary Arms SLx 1-10×28 rifle scope also has 2-night vision settings, and to be clear, that does not give you night vision capabilities. This simply allows you to illuminate the reticle if you are wearing night vision.
Adjusting the Primary Arms SLx 1-10 is typical of what you’d expect on an LPVO. The windage adjustment is on the right side of the scope and the elevation is on the top.
The adjustment caps are aluminum and come off easily. There is no quick adjustment on the caps, so you must take them off to make adjustments.
Adjustments with this reticle aren’t all necessary, with the ACSS Griffin M10S Reticle providing more than enough markers for on-the-fly shot corrections.
The nice thing about the adjustments is you don’t need any tools, coins, or spent casings to make your adjustments to get your scope zeroed.
You can just use your fingers to make adjustments once the caps are off and I can’t stress enough how much I like that small but important feature.
The reticle is powered by a single CR2032 3V Lithium Coin battery and it is located under the cap of the brightness wheel.
I try to keep these on hand regularly and change them out once a year, typically at the first of the year or right before the New Year, to make sure they are fresh and ready to go when I need the illuminated reticle.
This LPVO will hold up well and while I haven’t put it to the test I’m confident given the fact it is metal where it needs to be metal and the overall glass is clear.
Short of purposely abusing this optic, it’s going to hold up to even the most seasoned shooter.
If you are looking for an affordable 1-10x LPVO then the Primary Arms SLx 1-10 might be one of the best LPVO options for you.
I really like the eye relief on this optic; it doesn’t blur or degrade the eye relief when you zoom in, as some cheaper optics do.
I run this LPVO on my Sig Tread 716 and I can’t say enough good things about using this optic.
I’ve been using it for about 4 months now on my Tread, and it has really performed well after I sighted it, and it worked perfectly.
The price point of $449 is a bargain for an optic of this quality. I would not hesitate to recommend this scope to anyone in the market for a magnified scope. If you want something a bit more high-end, the Primary Arms PLx 1-8×24 is one of their premium scopes.
