Most Helpful Positive Review Worth every penny

The Sightmark T-3 provides some nice bang for your bucks. It’s pretty sleek looking while it does its job perfectly. The glass is crystal clear, the 3x magnification is there when you need it, and a simple flip to the side returns you to the red dot or other optic you employ for close contact. Th...

Most Helpful Negative Review Couldn't handle a little rain.

I bought this thing as a tester to see if I like magnifiers, and if they would be a practical addition to my rifle setup. I started by mounting this to an airsoft gun (since it gets used more). The image was clear enough, the eye relief was decent, and the mount is good. The problem is the rain. Th...

Decent 3x mag and flip to side, eye box and relief window could be bigger

by foremanjf, Verified Owner from CA, United States Written on April 26, 2024

Decent 3x mag and flip to side, eye box and relief window could be bigger...

Thats the only complaint same as their 3-18x Citadel even their eyebox isnt forgiving which if you had old eyes becomes and ever more important feature.

Sightmark T-3 Magnifier

by Davis, Verified Owner from FL, United States Written on February 28, 2024

Optics Planet had the best price after reviewing the internet. Reviews were good. Sits behind my Sig Sauer Romeo 5 as a co-witness with good alignment. Have all mounted on a Citadel Boss 25 12 gauge semi auto shot gun. Works great and rock solid.

Pros:

Sturdy

Cons:

None

Best Used for:

My shotgun or on an AR 15 as a co-witness to a red dot

Great optic on a budget

by Jeremy Harter, Verified Owner from TX, United States Written on September 21, 2023

Picked it up for a buddy on his birthday.. on the cheap. Boxed like it was new and I couldn't tell it was a refurb. Great choice to have something while you save for that Juliet. All in all, super satified with tye purchase of this equipment.

sightmark T-3 magnifier

by mrapp, Verified Owner from MT, United States Written on June 21, 2023

spent my big bucks on SIG stuff but still needed an extra magnifier so I chose this based on the low price alone, it is " OK " but for under $100 you can't go wrong small , a little dark but does ok, flip to side works well no awkward buttons to push QD mount is solid...not the quality of my SIG or Holosun so I us it to train with and really appreciate having the others for my go to. ! all good...no complaints.

Pros:

price, QD, good flip to side mount

Cons:

glass is a little dark

Best Used for:

Training

Great magnifier optic!!

by A Satisfied customer, Verified Owner from IN, United States Written on September 23, 2022

Works great and looks good. Needed a manifier that flips to the side to complete my build! Also, its reasonable as far as the price. Would love to get something like an eotech but as long as it works and does the job it was designed for, Im good!!

Good 'nuff

by Clay, Verified Owner from TX, United States Written on October 27, 2021

Field of view is very good at the cost of eye relief. I own an older sightmark magnifier that does the opposite so this one can be a positive for faster target aquisition especially for cost. The QD mount is also a big plus.

Pros:

Cons:

eye relief

Great Magnifier

by girlsshoot, from TX, United States Written on July 27, 2021

The magnification on this was truly incredible, and best of all there was no compromise on the clarity. I would absolutely recommend this device; it does its job, is much clearer than you’d expect, and the ability to flip it to the side is awesome. It is a little heavy but not nearly as much as it could be. Don’t think anything bad comes to mind thinking about this magnifier.
