The Trijicon RMR is well-known for being the most rugged mini reflex sight on the market and has found its way onto many pistol shooters handguns over the last few years. However, it was designed with duty use in mind and left out an important crowd—the competition shooters. Now competition shooters no longer need to make sacrifices with the release of the Trijicon Specialized Reflex Sight (SRO). Built from the same base as the RMR for mount compatibility, the Trijicon SRO is designed specifically for pistols to give competitive shooters the edge with their handgun. The most significant difference with the SRO is the increased window size allowing for a much larger field of view that rivals the competition. This allows you to more easily track the dot and switch to your next target much faster improving your split times. While the patented frame design is gone from this model, it still features an anodized matte black aluminum housing that is more than enough to protect the ultra-clear glass. With zero noticeable parallax and high-tech lens coatings, the glass in this mini red dot sight cuts down on glare and will stand up to heavy competition use. The Trijicon SRO Red Dot Sight is the next step forward in competitive handgun use, so don’t get left behind and drop this optic on your pistol.

Many popular features of the RMR have made their way to the SRO like the toolless adjustable windage and elevation and the 8 LED brightness settings as well as an automatic mode. Whether you have it set to “lock-out” and only use the auto-brightness feature or “lock-in” and secure your chosen brightness level indefinitely, the SRO still boasts up to 3-years of battery life. A popular new feature that fixes a shortcoming of the RMR is the top loading battery compartment, so you don’t have to remove the optic and re-zero just to change the battery. Waterproof down to 10 feet (3 meters) with drainage holes, the Trijicon SRO will run rain or shine. There are multiple dot sizes to choose from and this model features the 5 MOA dot optimal for fast target acquisition at shorter ranges.

My go to red dot

by -

Love my SROs. Especially on sale. While I like Holosun red dots, I'm tired of buying Chinese so I've decided to stick with US made dots. The SRO is my go to. I also have a DPP and while I like the window a bit better I'm not sure it's as bombproof as Trijicon stuff. I haven't tried any of the Sig dots yet but I guess their top of the line models are US made, which is cool.

Trijicon SRO, Best red dot, fast shipping

Trijicon Sro is the best red dot for competition shooting hands down. Clear glass, big window, easy target acquisition. A must buy.

Awesome sight

I have this installed on a “Glock 40” and it’s outstanding. The sight makes it extremely easy to acquire your target.
