Riton Mod 5 4x16x40 rifle scope



Quality and affordable optics is usually a juxtaposition, but with Riton, a Veteran and former Federal law enforcement owned company,  you can expect to get glass you can work with and not have to expend your entire gun fund. It was not long ago I reviewed the Riton Mod 3 4.5x18x40 front focal place rifle scope, you can read that review by following this link.   


Riton contacted me about doing another review on a bit more expensive, yet still affordable, rifle scope. It was not long after that I got their Mod 5 4x14x40, priced right at $500.


I mounted that scope on my Colt HBar Elite accurized AR-15 style rifle, a rifle of known quality, using Riton scope rings, and added the Gorilla 77gr match ammunition to test only the glass. After sighting the rifle in it was not a problem to get MOA 5 shot groups.

You can get a much better idea of how the scope worked and grouped at 100 yards in my video.


Here is a typical five shot 100 yard group, you will notice the one sighter round just the the Gorilla ammo box, getting the windage dialed in.


The scope has a left focus knob, adjustable for windage and elevation at 1/4″ MOA per click at 100 yards. I was able to run the elevation and windage out a few clicks and back in and the scope returned to zero. 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.


The scope ships with flip up caps to protect the glass at both ends of the tube.



It is no secret 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. Finding a scope that works as it should, that is affordable is not always easy to find. 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. I was able to get some solid five shot groups all were  MOA or better and reflected the results I am used to from this Colt using quality factory ammunition. Once again, Riton did not disappoint.
