Description
The ZeroTech Thrive HD 1x Micro Prism (THDMP120) is a 1×20 prism sight CNC-cut from a billet of 6061-T6 aluminium. Unlike a reflex sight, its reticle is laser-etched into the glass, so it stays usable without battery power and shows a crisp aiming point for shooters with astigmatism; illumination adds 13 brightness settings including three night-vision levels, with auto on/off, from a side-loading CR2032 rated up to 50,000 hours. Adjustments are 1 MOA per click over 90 MOA, eye relief is a generous 90 mm with a 23 m field of view at 100 m, and the Aimpoint T-2 footprint base comes with mounting heights of 1.1″, 1.4″, 1.6″ and 1.93″ so it can be set for AR-pattern, shotgun or lever-action rifles. The housing is argon purged and IPX7 rated, weighs 214 g with the 1.1″ mount and battery, and accepts Tenebraex flip caps (26FCV-010BK1 / 28MMFC-FCV).

Frequently asked questions
Why a prism sight instead of a red dot?
The etched reticle is sharp for astigmatic eyes and still visible with a flat battery; a reflex sight’s projected dot is not.
Which rifles does it suit?
The variable mounting heights cover AR-pattern lower-third and absolute co-witness as well as lower-mounted shotguns and lever guns.
Is a licence needed?
No. Sights ship Australia-wide without a firearms licence.
