The great folks at Primary Arms sent The Real Gun Guys editorial team a brand new lpvo rifle scope to test!

We unboxed it, mounted it, shot with it at the range, and took it on a deer hunt to see how it performs in the wild.

Even though Primary Arms sponsored this post, they asked us to put it to the test and give our honest opinion. So that’s what we’re gonna do.

Here’s our experience and opinions after testing the Primary Arms SLx 1-6x24mm SFP Rifle Scope Gen IV with Illuminated ACSS Nova Fiber Wire Reticle with Red Dot Bright®.

Unboxing

Scope unboxing

The Primary Arms SLX® 1-6x24mm SFP Gen IV LPVO Rifle Scope came in a tough, well-packed box that felt solid. Inside, everything was neatly arranged, with foam padding keeping the parts from moving around so you don’t end up with a broken or scratched scope.

The box included everything needed to set it up:

  • The SLX 1-6×24 SFP scope
  • Mounting tools for easy installation
  • Lens cleaning cloth to keep the glass clear
  • Lifetime warranty card for peace of mind
  • Product manuals with step-by-step instructions
  • Bonus: GLX 30mm cantilever scope mount

Mounting the Scope

I met up with Chris Litton at his shop to mount this scope on my Savage MSR15 Recon 2.0 rifle. We used the Primary Arms GLx 30mm Cantilever Scope Mount, which is designed to hold the scope firmly in place.

After removing my Vortex Sparc AR red dot sight, we mounted the new Primary Arms SLx scope. The mounting process was straightforward, thanks to the quality design of scope, mount, and simple instructions. To ensure accuracy from the start, we used a laser boresighter to align the reticle roughly at about 10 to 20 feet. This step made it much easier to fine-tune our shots at the range later.

  • The GLX 30mm Cantilever Mount made setup easy and ensured the scope was aligned properly.
  • The clamping system was strong, keeping the scope locked in place even after shooting multiple rounds.
  • The torque settings were clearly marked, making it simple to tighten everything correctly without overdoing it.

Build Quality & Design

The SLX 1-6×24 SFP scope feels sturdy and has a matte black finish that’s supposed to resist fingerprints and glare. It looks good and seems built to last.

  • The turrets click firmly, making it easy to adjust windage and elevation with accuracy. Each turn feels precise and reliable.
  • The lens covers have a good snap to them and stay in place.
  • The GLX 30mm Cantilever Mount makes sure the scope sits at a comfortable level, providing good eye relief and a steady aim.

Field Testing the Scope

We took the gear out to the range to sight in the scope at 50 yards and 100 yards. Taking turns shooting several rounds each with the new Primary Arms scope we got it dialed in. We tested out different brightness settings of the red dot, different zoom levels, and tested the mil hash marks of the reticle.

Features & Performance

  • The ACSS reticle helps with quick aiming and long-range shots. It’s simple to use and makes adjustments easy.
  • The 1-6x magnification range is very useful. At 1x, it works like a red dot for fast aiming. At 6x, it provides clear vision for distant targets.
  • The glass is sharp and clear, with no blurry edges. The multi-coated lenses reduce glare and improve brightness, making it great for different lighting conditions.
  • With 11 brightness settings, the reticle is easy to see in bright sunlight or low-light conditions.

Range Test Results

The best accuracy I achieved with this scope on my Savage MSR15 rifle was a 1 inch group at 50 yards and a 3 inch group at 100 yards.

That’s about the same level of accuracy Chris shot as well.

One of my 100 yard shots did hit dead center, which made me feel like I knew what I was doing.

Overall, those numbers are definitely accurate enough to hunt and kill deer, hogs, and coyotes in most cases at 50 yards.

At 100 yards it will still deliver a kill shot if you’re aiming in the right place.

“You could get a headshot on a squirrel at 50, and a heart shot on a deer at 100.”

Chris Litton after mounting and shooting the Primary Arms SLx 1-6x24mm SFP LPVO Rifle Scope Gen IV

Those words would end up being prophetic when we took the scope out on a hunt.

But we weren’t happy with these results because it left questions in our minds:

  • We used budget target ammo, which might have lowered accuracy. If we used match-grade or custom ammo could we improve results?
  • My rifle may not be the most accurate, and Chris suggested testing the scope on a precision rifle for better results. Would it be worth moving the scope to a different rifle?
  • The windy and cloudy weather may have affected our shots a little. Would a better day give better results?

So we went back to the range a few weeks later and used custom loaded ammo that Chris made in his shop.

This seem to make all the difference when Chris shot using my same rifle, but different ammo.

He improved his accuracy from a 3 inch group to a 1 to 1.5 inch group at 100 yards.

Basically, he was twice as accurate with better ammo, even though we kept the scope on the same rifle.

For some reason my shots were all over the place our second day at the range, but it seemed to just be my own nerves. Just had an off day.

Now it was time to take the scope with us on a deer hunt.

Hunting Results

Once we were confident the scope was dialed in at the range, we took it out on a deer hunt. I had my Savage MSR15 loaded with Chris Litton’s custom loaded 223 ammo rounds to ensure ballistic accuracy.

At the end of the second day of hunting deep in the forests of Alabama, I finally had my chance when a deer crept out of the woods to my right at about 4:30pm. Sunset wasn’t until 6pm, so we still had plenty of daylight.

I set the red dot to it’s lowest brightness setting and got the deer crosshairs.

About 20 minutes earlier my son, Ezekiel Vega, had just shot a doe and it was still on the ground motionless.

The second deer was curious and a little spooked, but making it’s way to the deer feeder. Right as it settled in, a gun shot rang off in the distance from someone else in our hunting party at different location.

The deer bolts back and forth, zigzagging around the clearing. But it was hungry, so it settled down and came back toward the corn.

The whole time it’s moving around, I’m tracking it through the scope trying to keep the red dot right behind the front shoulder.

Finally, it pauses as it stands sideways about 30 to 40 yards away.

While it looked back at the dead dear and the corn, I started squeezing the trigger while keeping the red dot on target.

Boom. Heart shot.

It drops its head instantly, then runs with its head down for about one hundred yards. We can hear it crashing through the woods to the left of us but lost sight of it.

We waited about two hours until legal hunting hours were over (30 minutes after sunset), and then went to find our deer.

My son’s deer was right in front of us. He picked up and carried it toward the truck.

My deer was harder to find, but thanks to a well-trained deer dog trained by the land owner, we were able to find it about 10 – 20 yards into the woods beyond the clearing we were hunting.

Turns out it was a nub buck, or button buck. We were supposed to only be hunting does on this trip, but I didn’t notice the nubs even though I checked the head through the scope. The ears seemed to cover the nubs from my angle. But the land owner was forgiving. Especially since this was my very first deer harvest.

I drug it out by the front legs and loaded it in the truck with the help of my son.

The Primary Arms SLx LPVO scope was dead on target for this hunt. Having the red dot to quickly find my place was critical since this deer was jumpy and on the move.

Overall Opinion

Chris Litton’s Opinion:

Chris was pleased with how the scope performed. Once we tried it precision hand loaded ammo it performed great, delivering close to 1 inch groups at 100 yards. For a 1-6x scope on an AR platform he feels like this is about as good as it gets performance wise, given the ammo and rifle used in the test. Chris believes this scope is worth buying given the results we got, the clarity of the sight picture, the red dot brightness, and the value given it’s lower price compared to other LPVOs.

Paris Vega’s Opinion:

I had a great time shooting with this scope. The sight picture was large and clear. The red dot was super bright. It was actually so bright that I liked shooting it best on nearly the lowest brightness setting. This is the first LPVO I’ve shot that had a built in red dot. The flexibility of having the ability to go from 1x to 6x with the red dot staying perfectly in view the whole time was great. I’m going to spend more time with it and take it in the woods this weekend to go find some groceries. UPDATE: Deer acquired. This scope was effective on the range and in the woods. I was able to hunt and kill a deer using this scope.

Pros:

  • Crystal-clear glass with a wide view
  • Great value compared to higher-priced LPVOs
  • ACSS reticle makes aiming easy and accurate
  • Illuminated reticle with 11 brightness levels
  • Easy-to-use magnification ring for quick zooming
  • Precise turret adjustments for fine-tuning aim
  • Works well for hunting, self-defense, and tactical shooting
  • Strong, durable mount that holds zero well

Cons:

  • A little heavier than some similar LPVOs
  • Magnification ring takes a good bit of pressure to turn at first, but moves more easily over time with use.

Summary

We thoroughly tested this LPVO scope in a variety of situations, and we can confidently say that the Primary Arms SLX 1-6×24 SFP scope with the GLX 30mm Cantilever Mount make a great combination for shooters who want reliability, durability, and affordability.

Whether for tactical shooting, self-defense, competition, or hunting, this setup performs well at a reasonable price.

If you need a versatile, high-quality LPVO scope without spending a fortune, this is a great option. It’s helped me literally put food on the table now that we’ve had a successful hunt while using this scope.
