Most Helpful Positive Review Pull the trigger and get it
To be honest, this is a great product. I was skeptical of what a $100 magnifier would entail, but I know Primary Arms has a great reputation so I chose this over Vortex and the big name magnifiers. As far as a comparison to my Sig Romeo w/ a Juliet magnifier and my Eotech XPS & Eotech magnifer, I ca...

Most Helpful Negative Review Disappointing
I have to be honest I was expecting more from this magnifier. I wear glasses (near sighted) and could not get a clear sight picture. I have other "low end" magnifiers that are better than this including Sight Mark and Vortex and recommend those over this.

This is a great magnifier for the money. This is the second one I’ve bought because I love the red dot/magnifier combo.

Ler, gen 4 , 3x magnifier

by Meko, Verified Owner from LA, United States Written on February 23, 2026
This is my second purchase. Getting 2 more. 100 plus s&h is an absolute steal. Compared to the rest.. this is a no brainer. Like Hop said, they are all the same. Its pretty hard screwing up a magnifier, seriously.. premium glass, durability from bumps and fog proof. All you need.
Pros:
  • Price, quality , function
Cons:
  • No mount, eye box can be strict
Best Used for:
  • Sbr, pcc, within 200 yards

Really, REALLY nice magnifier

by IMMEKO G. FYS, Verified Owner from LA, United States Written on February 13, 2026
Im going to be honest and frank- Ive tried sightmark 5x and 3×, I've tried holosun 2x , I've experienced Eotech, monstrum, utg leapers and Burris. I own 3 sig romeo 5x micros. This primary arms LER 3x magnifier is a breath of fresh air.. seriously. Im a magnifier thot.. after installing it on my 13.9" , i IMMEDIATELY purchased another one. Pro tip! Use sightmark QD FTS mounts on this 3x and your cheating the system (thier more solid then the actual sightmark magnifiers, lol) ..assuming you already own a sightmark 3x or 5x, same mount. Keep in mind, its "Long" eye relief, not "Large". So install it correctly. .. nerds.
Pros:
  • None
Cons:
  • No mount , shipping, shipping cost, lack of color options, no 4 or 5x options, no tools for adjustments

clear glass, easily mounted

by daniel, Verified Owner from KY, United States Written on January 25, 2026
Just a practical, non gimmicky magnifier. You can really go wrong with picking this and the price tag doesn’t hurt. Got it on a unity FTC mount behind an eotech. Looks great

Very good magnifier from a reputable company that specializes in optics

by HC, Verified Owner from TX, United States Written on October 23, 2025
Very nice clear magnifier from a reputable company, and with good warranty. Image is very clear and no distortion at the edges. I have it on a .45 PCC so not a huge amount of recoil, but seems sturdy so far. It's on a Leapers UTG flip to side mount which is a little tight to flip, but seems to hold the magnifier very steady with no shifting back and forth.

Great product for the money, no mount.

by Nickname, Verified Owner from ID, United States Written on December 6, 2023
Seems really solid. Only have about 100rds through it so far. But the clarity is on point with optics around the 200$ range. The eye relief seems better than those optics as well. Only real complaint was there was no mount (I may have just missed it in the description) but you can use any 30mm scope mount, or buy a flip to side/center. Overall. Would recommend.
Pros:
  • Price
  • Clarity
  • Eye releaf
Cons:
  • no mount

Great Eye Relief

by Eric, Verified Owner from IL, United States Written on May 23, 2023
This is a great magnifier when paired with the UTG flip to side mount. The only thing that isn't great are the see through covers. They impair your view and aren't really usable trying to look through
Pros:
  • value
  • eye relief
Cons:
  • no mount

Primary arms magnifier

by Scott, from TX, United States Written on January 27, 2019
Read reviews before you buy magnifiers. I did and I ended up buying this one. Reviews are right on. Good quality and nice for my new build. Crisp and clean and unbeatable for the money and that was the determining factor for me. Rates as high as others that are 2 and a half times more money. You can not go wrong with this purchase..... Nice
Pros:
  • Cost and quality
Cons:
  • none yet
