It fits perfectly to the Zoraki pistol, which only has one groove on the 22mm rail. You can choose from several reticles in green and red, with the ability to adjust brightness.
-
I've been using it for a year on the RK-74 CQB from G&G. I am very satisfied. Nice illumination and the choice of the most suitable reticle definitely speeds up the aiming process. If you're starting with airsoft and want a relatively inexpensive but good quality collimator for short-range "combat" or dynamic training, the Theta Optics Ris Open is a good choice.
-
Great collimator, the sight is large, which is a plus, fairly high mount, it's easy to aim.
-
This is exactly what I was looking for. A large, open collimator for airsoft at a reasonable price.
-
Great, practical, inexpensive but good.
-
I am extremely satisfied with it. It is much bigger than it seems in the picture, which is definitely a plus if you mount it on a rifle. The brightness of the dot can be adjusted thanks to the knob on the left side. There are no defined levels as in most collimators, which allows for precise adjustment.
-
Great collimator for ASG. Many illumination options. I recommend it.
-
Great collimator, although not everyone will like it. A lot of adjustments.
-
These are some of the most practical and successful open collimators. Above all, the appropriate dot size. Secondly, and equally important, the ability to change the dot shape to a dot, dot in a circle, cross with dot, and cross with dot in a circle. And also red and green colors, and 7 brightness levels, and easy access to the battery and switch. Besides, the sight is fairly large. The collimator is slightly bigger than it looks in the pictures.
-
Nice small collimator with RIS rails on 3 sides, so I recommend it and I'm happy with the purchase!
-
Cool collimator with a unique look!
-
I received the collimator as a gift, an excellent alternative to a scope. On my M40 – superb. Almost like the T88S-R from BF Bad Company 2.
