Tangent Theta

Rifle Telescopes for Professional Marksmen

Tangent Theta Incorporated is based in Halifax, Nova Scotia, Canada and was established to design and build a series of rifle telescopes specifically for the requirements of Professional Marksmen.

Our company has assembled an extremely experienced rifle telescope development team consisting of optical designers, mechanical designers, engineers and international-class long range marksmen. All have either worked for or consulted to the most prestigious names in the optical sighting systems industry.

Our goal is to design, develop and produce rifle telescopes that are beyond reproach in all aspects of design, utility, and service performance.

Tangent Theta rifle telescopes are built in our own manufacturing facility in Halifax and are distributed internationally by Armament Technology Incorporated.
