Most Helpful Positive Review I like it!
I am by no means an expert. I'm only now learning to build AR-15s, do sight adjustments and trying to shoot beyond 100 yards, but I really liked this scope. Easy to adjust and one adjusted it helps put the bullets where I want to. And it looks great on my FDE rifle.

Great Optic

by Jerry h, from NV, United States Written on July 15, 2018
Great optic zeroed quickly. Right out of the box I was almost zeroed took minor adjustments. The reticle is sweet . Could be bigger but works well. This my second I have both the 3x and on another rifle I have 5x. Can't go wrong with either the price is good and quality is wonderful.
Pros:
  • Quality and price
Cons:
  • For me small reticle
Would recommend: Yes

Awesome PA Scope

by Barry Brown, Verified Owner from TX, United States Written on June 25, 2018
This is a great optic! Quality and build are well beyond the price. As with other PA scopes the design and manufacturing is very good. I love the ACSS reticle; it is one of the best out there. The illumination settings are crisp and effective. The flip-up covers are good quality too. I highly recommend this for short range, CQB, home defense.
Pros:
  • Price
  • Build quality
  • reticle
  • primary arms
Cons:
  • None
Best Used for:
  • Home Defense
  • CQB
Would recommend: Yes

by Jeff S, Verified Owner from OH, United States Written on April 7, 2018
Great optic, well beyond the price. Sturdy design and manufacturing. MOA is excellent. Chevron is one of the best out there, and illumination settings are crisp and effective. Comes with flip-up dust covers which can be removed easily if desired. Highly recommend for AR platforms.

Primary Arms 3x prism scope

by Rob, Verified Owner from NJ, United States Written on March 11, 2018
I spent a lot of time researching which Red dot optic scope I wanted for my AR. It came down to th Primary Arms Prism scope and the Vortex 3X prism scope. I dealt with Vortex before and they make a great scope, but in watching the reviews I liked the Primary prism scope more and I also liked that it came FDE and was almost $100 less. I couldn’t be happpier with my decision it’s a great scope, easy to use, very clear and high quality. I dont think you can get a better one in this price range. If your looking for a very good optic scope I would suggest the Primary Arms for sure.

Awesome purchase

by Lilbull, from TX, United States Written on March 10, 2018
Well made, great optics, a little on the heavy side but other than that you can't beat it for the price. The ACSS reticle is outstanding and the glass is very clear, I recommend purchasing the honeycomb sunshade for an extra $30

Primary Arms 3x9 Compact Illuminated Prism Scope-FDE

by Jose Guerrero, Verified Owner from TX, United States Written on February 9, 2018
This scope is great for the money. Optics are clear and the etched reticle is awesome. The illumination is spot on for low light conditions but the lower settings not noticeable during day light conditions. Outside of that, highly recommended product and will purchase another another for other projects.

This review is more about my old eyes

by JT, Verified Owner from NV, United States Written on January 28, 2018
First I purchased a Red Dot from Optics Planet for my 556 pistol. When I got it, I powered it up, looked thru it and all I saw was a large red starburst instead of a crisp dot. Called OP, no problem, they said send it back and I chose the store credit opption . It took about 2 weeks for the credit to go thru and by then I had decided on this 3x prism scope from Primary Arms. And like most of the other reviews say it's a little heavy , but it's built solid and looks great. But when I looked thru this one the reticle was blurred with my glasses on but clear and crisp without them. Called OP customer service and the rep said that sometimes if you can't use a red dot, a prism scope may not work either. Again, no problem, send it back.
Optics Planet and there return policy are great. If you have good eyes this looks like it would be a great choice, but if not, do a little more research. For now,I'm using a 1-6x scope that I already had and that works great for me but it's 1/2 the size of my firearm. The search continues.

Outstanding Sighting System designed for the Nato 5.56 Modern Sporting Rifle. Excellent Rifle Scope!

by Fly Fisherman 777, Verified Owner from WA, United States Written on December 23, 2017
Simple and Easy! Yes, Primary Arms has done it at last. A specific type of Compact Rifle Scope designed for the AR15/AR10/AK47 rifle platforms. This well designed unit incorporates the new ACSS Reticle, (Advanced Combined Sighting System) and is very simple to use. Here is the best part. If you are Far-sighted, turn the sighting ring Clockwise and Counter Clockwise for Nearsightedness. It is a one time adjustment for your very own eyeball. This makes it easy to zero in if you are a shooter with some aging eyesight issues. In addition, It is very simple and easy to set up, with easy to understand instructions included in small 5 page instruction booklet with Ballistic chart. They explain the sighting system in easy to understand language. They even include a guide on how to hit a moving target. Wow! This is the best firearm accessory purchase I have made in many years. Thanks Primary Arms! I will be purchasing another one very soon for my bolt action Mossberg MVP308.
Pros:
  • Reticle and Eye Sighting System
Cons:
  • I can think of any at this time.
Best Used for:
  • Precision shooting
Would recommend: Yes
