Sightron Rifle Scopes - Hunting Scope Models

In business for nearly two decades, Sightron scopes are no longer the new kid on the block. Over the years they have expanded the lineup to included, riflescopes, spotting scopes, binoculars, and red dot scopes. When Sightron rifle scopes initially hit the market nearly twenty five years ago they made an immediate impression on hunters and shooters, and quickly gained a reputation for providing good mid level optics at a more reasonable price than most of their competition. However, over the last several years there seems to be a lot less buzz around this once hot brand, but make no mistake about it they are still in business and going strong.

Sightron SIII – The premium series of scope in their line up, SIII scopes are built on a 30mm main tube, which is 2x as thick as their 1” models, for greater strength and the ability to stand up to rugged use. SIII models are also equipped with side focus parallax adjustment knobs, and are fog, water, and shock proof. SIII models are also equipped with Sightron’s ExacTrac system for windage and elevation adjustments. Finally, Sightron SIII scopes have a seven layer lens coating for increased light transmission.


Big Sky SIII 10-50x60

Sightron SII Big Sky – The main difference between the SIII and SII Big Sky series is that the SII Big Sky series in built on a one inch main tube instead of a 30mm tube like SIII series. However, the SII-Big Sky retains the ExacTrac windage and elevation feature, the side focus knob for parallax adjustment, and the special seven layer lens coating called ZACT-7.

SII Big Sky

Sightron SII Big Sky 4.5-14x44


Sightron SII – Like its Big Sky brother, the standard Sightron SII series is built on a 1” main scope tube. However, scopes in this line up that are equipped with parallax adjustment do so by way of an adjustable objective instead of a side focus knob. The standard SII series does feature their patented ExacTrac system for wind and elevation corrections, but the SII series lacks the special ZACT-7 lens coatings for increased light transmission.


Sightron SII 3-9x42

Sightron SI – This is the entry level line in the Sightron scope series. Again, these scopes are built on a one inch frame, and most of the series models fall around the popular big game magnification of 3-9x. Since the highest power in the lineup is a 3.5-10x magnification model no parallax adjustment feature is offered in the SI product line. By the time you get down to this entry level model, as you may have guessed, all the extra and special features mentioned in the above models are gone. The is no special windage and elevation adjustment systems, no special lens coatings…etc; these are a few frills entry level scope.
