Most Helpful Positive Review Great scope for the price
I really like the scope and would have gave it five stars but the windage/elevation adjustments are really mushy and not audible. On the positive side the reticle is probably one of the brightest I've seen in a LPVO

Scope review

by Jerry, Verified Owner from MI, United States Written on March 29, 2026
Maybe this is true for all of these type of scopes, but this one in particular was like looking through a fisheye lens. The image in the very center was clear, but distorted around 1/3 the viewing area. I originally purchased this scope for my bolt action rifle, but quickly realized it is meant for “combat shooting”, not precision shooting. I moved it to an AR style rifle. Aside from the fisheye, the turret adjustments are nowhere close to what they show on the scope.
Pros:
  • Illuminated recticle is nice
Cons:
  • Turret adjustment is way off
Best Used for:
  • Basic combat shooting
Would recommend: No

amazing value

by mike3p, Verified Owner from OK, United States Written on December 31, 2025
This is hands down the best value LPVO I have ever used. Clear glass, nice reticle and easily adjustable. I put this on a Q boombox and it is perfect for managing my hog problem.

Primary Arms SLx 1-10 LPVO Review

by Dan H., Verified Owner from CA, United States Written on August 31, 2025
ITs a good LPVO scope with a great BDC reticle. Its a great addition to my AR15. Took it out recently and zeroed at 100 yds then shot at 10"x10" plate at 600 yds. Easy to bracket your shot during switchy winds.

Optics Planet was great to deal with and fast delivery.
Pros:
  • Great reticle and clear optics for the price.
Cons:
  • None
Would recommend: Yes

1 X 10 power LVPO

by Ken Hall, Verified Owner from NE, United States Written on February 8, 2025
I received this scope but have not mounted it yet.
After playing with it I am impressed so far.
I own a number of scopes high end and mid range including a 1 x 8 LVPO strike eagle by vortex.
I would say this scope has a better glass from what I can tell so far.
A little better eye box.
and I like the reticle design a lot for an LVPO.

it gives you great versatility from up close and personal to out there at 1,000 yrds.
Putting this on my Grendel should be a perfect match.

Also going to get primary arms wake and shake battery cap for it.
A major plus as well.
Wish they would mae them for all the major optics out there.
Best Used for:
  • Ar 15 and equivilant platforms
Would recommend: Yes

Great Bang for the buck

by Aaron Folks, Verified Owner from WY, United States Written on March 27, 2024
This P.A. SLX 1-28 has been solid so far , after over 500 rnds through the AR-10 it’s mounted on its maintain an excellent zero , the construction, fit and function has been perfect so far , the quick zoom dial is smooth and fast , the windage and elevation adjustments are crisp tight clicks , the glass is good up to 10x then there is a bit of frost around the edges, the illuminated reticle is nice , and has multiple brightness levels however it’s certainly not going to be anywhere near the illumination of something like an Eotech . Over all it’s a great option if you want a reliable optic with out breaking your bank.
Pros:
  • price and quality
Cons:
  • Glass around edges could be a little better
Would recommend: Yes
