ZeroTech Optics Upgrades Thrive HD Line of Reflex Sights

Red dot sights are commonplace now with a lot of shooters. One of the main selling points of these optics is the auto-on and auto-off functions. When speed and accuracy are needed, a sight that automatically turns on when it senses movement can make the difference on the range or with concealed carry. That’s where ZeroTech Thrive HD Reflex sight comes in with its advanced shake awake technology. It’s ready to go when you are. 

ZeroTech Optics has upgraded its line of Thrive HD Reflex Sights with shake awake technology making it ready to go when the shooter is.

Built on a popular footprint, the Thrive HD Reflex will mount to most firearms and it’s available in both low and high mount options. It comes standard with a Picatinny rail interface, allowing it to fit on shotguns, lever rifles, AR platforms, and many more. By removing the Picatinny rail interface, the Thrive HD reflex sight can mount directly to pistols with a slide cut and many accessories designated for the direct attachment of a reflex sight.

ZeroTech Thrive HD High
The Thrive HD Red Dot Reflex Sights will mount to most firearms, thanks to the included Picatinny rail interface allowing for mounting on rifles, shotguns, AR platforms, and more. Without the rail, it can direct mount on pistols with a slide cut. (Shown here with the high mount option.)

The Thrive HD Reflex Sights have a 3 MOA Red Dot with 11 adjustable brightness settings. It runs on a side-loading CR2032 battery so there is no need to remove it from the mount to swap the battery and has a max 50,000-hour battery life (on the lowest brightness setting). The sight is guaranteed waterproof and shockproof and comes with a molded rubber cover.

Patti Miller is one of the most awesome females in the tactical/firearm (or any) industry. Imagine a tall, hawt, dangerous Laura Ingalls Wilder type with cool hair and a suppressed blaster and you’ll be getting the idea. What’s interesting is that in addition to being a willing brawler and intrepid adventuress, she’s also an Ent/Ogier level gardener and a truly badass baker.
