Riton Optics, affordable quality glass.


Riton USA  , a Veteran and former Federal law enforcement owned company, sent me one of their RT-S MOD 3 4.5-18X40 rifle scopes to go over and see what is what.  Since that particular optic has a bullet drop compensator for 5.56 I decided to mount it on an AR-15 that I have reviewed in the past, the Double D Armory SST. You can read that review by following this link,  so I know how the rifle performs.  To eliminate other variables I used match ammunition from Gorilla Ammunition, and I also know how it performs.


Using a the XSKEL1 GEN 2 mount from Warne Scope Mounts, I got the Riton optic mounted and bore sighted and ready for the range. The first groups I shot were with the 69gr Sierra Matchking loaded by Gorilla Ammunition to dial in after bore sighting. I was able to get it dialed in and print some decent groups before I made the transition to the 77gr and really put it to work. I managed to get a couple half inch five shot groups as we were going through the test.

Dialing the magnification up and down on this second focal plane scope did not change the point of impact as well as adjusting the windage and elevation up and back to see if the point of impact would go back, and it did.  Over the course of the day we went through about 100 rounds and once dialed in, the RT-S MOD 3 held zero throughout the day. After two trips to the range and throughout shooting and packing the rifle in and out the scope held zero. The BDC reticle was handy for quick hold over for changing distances. Though using a BDC reticle correctly does require some homework on your part knowing your ammunition and rifle, but once you get that squared away it is a nice feature.


The adjustment knobs were easily manipulated with an audible click that you could feel at each adjustment. The focus knob is located on the left of the turret across from the windage knob and focused smoothly.

It has been said many times that you get what you pay for, and there is a lot of truth in that, but you can still get quality optics without having to take out a second mortgage. Being able to get a scope that works as it should, that is reasonably affordable is not always easy to find. Also there is a market for quality inexpensive optics with not only target shooters but also hunters, that may abuse their equipment a bit and don’t mind getting it scratched up. I have a few expensive scopes and I treat them as such, but being able to mount an optic and not be afraid to throw that rifle in the trunk is equally as important. Since Riton offers unlimited lifetime warranty on their optics you won’t be afraid to take them in the field and use them as they were meant to be used.


Throughout the day I was able to get the rig dialed in and got some solid three and five shot groups all were sub MOA and reflected the results from the initial tests of the rifle, so that lets me know the scope and mount did not take away anything from the rifle’s potential.

I think Riton USA did pretty well with this model and I look forward to working with them in the future.

Rition USA optics 

Double D Armory

By Hunter Elliott

I spent much of my youth involved with firearms and felt the call early on to the United States Marine Corps, following in my father's and his brother's footsteps. Just after high school I enlisted and felt most at home on the rifle range, where I qualified expert with several firearms and spent some time as a rifle coach to my fellow Marines. After being honorably discharged I continued teaching firearm safety, rifle and pistol marksmanship, and began teaching metallic cartridge reloading. In the late 1990s I became a life member to the National Rifle Association and worked with the Friends of the NRA. Around that time my father and I became involved with IDPA and competed together up until he passed away. I began reviewing firearms for publications in the mid 2000s and have been fortunate to make many friends in the industry. Continuing to improve my firearms skills and knowledge is a never ending journey in which we should all be committed. I am also credited as weapons master on a few independent films.
