Most Helpful Positive Review Great Optic At A Great Pricew

For those of you who want a Trijicon ACOG but can't afford the $1200+ price tag the Primary Arms 5X Prism Scope is a fantastic substitute at only $280. Mounted the P.A scope on my M4 (16" barrel) because I was not happy with the accuracy of an unmagnified red dot at 50-100 yard ranges. My only conce...

Most Helpful Negative Review 5X prism scope review

Quality built scope, crystal clear glass and heavy duty mounting system, unfortunately I had to return it and replaced it with a 1-6x24 primary arms scope. The reticle on the 5X is so small I could not read the range estimator and I could barely see the distance numbers. It's too bad because if the ...

The SLX 5x36mm Gen III Prism Scope works very well. The red dot sight mount was perfect for my use.

Perfect scope

by Cimmerian, Verified Owner from WV, United States Written on July 5, 2026

Was worried fixed 5x magnification would be a to much, but it's actually perfect.

Tunnel vision

by Robert, Verified Owner from NM, United States Written on June 23, 2026

I wanted to like this optic, but ultimately this is designed in such a way that you will not get a full visual- field picture, and will end up seeing a large black ring around everything, and this is from the internals of the optic, and does not include the external optic housing. But i will still recommend the scope since it's built like a tank, has clear glass, and is in a $ budget range for a 5x that needs exist for this of us that are not rich. Plus the anti reflective device on a prism optic is awesome. Note: The tunnel vision does not exist on the newer microprisms, and they do give a stunning sight picture.... but I wanted something like this with a more robust mount and housing.

Crisp and clear

weight

miniscule reticle

by Dingo, Verified Owner from MT, United States Written on March 10, 2026

The pictures on the site, even though they are dressed in a circle to like like the actual view through the eyepiece, are very misleading, the actual reticle is very small and unlegible, should either just be the light up center point or made to the proportions shown in the picture. Seems very solid, but the reticle ends up looking like a lot of scratches and smudges.

Chinese Junk

by Sam, Verified Owner from AZ, United States Written on January 8, 2026

I bought this on super sale a few years ago and used it once. It's heavy, has horrible relief and minimal magnification. After that one use I came home, pulled it off my rifle and reinstalled BUIS. Spend your $$ on a nice optic. This thing is junk.

Pros:

None

Cons:

Heavy
Poor magnification
Poor Relief

Best Used for:

junk bin

Great fixed power prism scope

by DJT, Verified Owner from MI, United States Written on September 2, 2025

I as actually had the slx 5x micro prism which i reluctantly brought and didnt like the afterthought engineering idea on how to add a red dot using the 12oclock mount and ended up returning it and got this 5x36 which has the picatinny rail built-in which works way better if you intend on mounting a red dot. Although this one is quite a bit heavier and doesn't have the instant on feature, it sits much lower, is more stable and looks like it should as opposed to the micro prism which wasn't really designed to accommodate a red dot effectively.

5x fixed mag

by JRJ, Verified Owner from TX, United States Written on August 15, 2025

For a ar platform I dont believe I'll ever go back to a variable VP scope again. I noticed on my last red dot that I always used the magnifier.wha have the magnifier when I can have the whole package and more in one unit. Cristal clear retical. The prism is definitely the way to go for clarity

Pros:

Clarity of sight pic.

Cons:

Battery Life

Best Used for:

all around
