Do-all optic

by Matt S., Gear Expert from IL, United States Written on January 8, 2019
High quality optic that comes with all the features and accessories at a price better than their Swedish competition.

This optics is built to go hard while still offering you options. Reticle choices, mount choices, flip cap choices.

Solar panel and battery give you 100,000 hrs of usage.

Motion activated feature powers optic on with movement and off with inactivity.

Unbelievable value. Mounted this on my beretta 1301 with a CROM mount and it is a beast.
Most Helpful Positive Review Expensive but excellent
The holdover dots are great, the solar sight gives the excellent battery life and the weight is easy to manage. This is my go to sight for any hard use gun. Beat option in the price range and can do it all

my favorite red dot

by John, Verified Owner from NV, United States Written on January 11, 2025
Great battery life, clear, durable, easy controls, decent mount but I mount mine on the unity S mount. My go to red dot over any other one. It’s really nice to have clear covers on the optic as well, you can use it without ever opening the cover.

Great red dot

by Don, from GA, United States Written on November 23, 2022
This red dot is awesome. It's clear, and I don't get the starry effect due to my astigmatism. It's robust, and holds zero. Comes with a lot if accessories too, including a kill flash cover. Great optic for the price, highly recommend.

Circle-Plex accolades

by Shane, from KY, United States Written on July 11, 2022
Tried the dot before the plex, kept the Circle-Plex. If you have an astigmatism, it is a Godsend. Rather than a small ragged slash, can actually see the "crosshairs." Agree with everything else everyone says about the sight in general, i.e., it's really good.
Would recommend: Yes

Best Reddot on thr market

by Justin, Verified Owner from TN, United States Written on June 10, 2022
If you’re looking for an optic to trust your life choose this. I’ve used just about every premium red dot optic on the market and this one is the one that is the best. Battery life is crazy good, glass is clean, rugged, and holds zero. Tomorrow if I was breaching the gates of h*** this would go on my gun. It’s passed the most harshest test that the boys can put it through as well.
Pros:
  • battery life
  • works
  • Recticle design
  • SOCOM Selected Contract
Cons:
  • price
Would recommend: Yes

Romeo 4T - Rugged, Bright and Great Reticles

by GulfWarMedic, Verified Owner from NJ, United States Written on June 26, 2021
Very pleased with this red dot sight. Very solid unit, easy to adjust, auto on/off, excellent battery life of up to 50,000 hours, nice all black finish, and the solar backup works as advertised. High quality all around, and I expect it to last a long time. My first Sig sight, and glad I picked it over the competition in this price range. Really like the four choices of reticles, and the sharp, clear glass. Great sight picture that’s easy and quick to pick up. Installed this on my AR-15. The 1/2” bolt mount is going to prove more secure than the QD mount on the 4H and 4S. The 4T comes with all of the mount options you’ll need. The extra flip up clear lens cover was a nice bonus. Once suggestion for Sig would be to offer/include a padded cover to slip over the sight when storing the gun. Would help to keep dust off the lenses and prevent banging up against other guns. Although, this thing is built like a tank! Glad I spent the extra money over the Romeo 5. It’s worth it for the features and extra durability, without braking the bank.
Pros:
  • durable
  • Warranty
  • Mount and lense covers included
  • High qaulity
  • feature rich
  • easy to install
  • Retical is fantastic
  • Battery Life and Availability
  • Clear glass Crisp red dot
Cons:
  • Can not think of any
Best Used for:
  • Range
  • Training and Battle
  • Home defense
Would recommend: Yes

Pros:
  • Nice size
  • easy to install
  • Looks great, and works great!
Cons:
  • None
Best Used for:
  • AR 15 co-witness
Would recommend: Yes
