ZeroTech Thrive HD Micro Reflex 1×21 Sight

Red dot and reflex sights let you aim with both eyes open and acquire targets quickly — ideal for handguns, shotguns and AR-type rifles. ZeroTech is an Australian optics brand known for good-value, feature-rich scopes.

• Size: micro
• Window: 21mm

Check that the sight’s mounting footprint matches your pistol’s optic cut or your rail, and use a thread-locker on the mounting screws.

Keep spare batteries on hand and zero the dot with the ammunition you will be using.

Use quality rings and bases, keep screws torqued to specification and check your zero regularly, especially after travelling. Clean lenses gently with a soft brush and lens cloth, never with a shirt or tissue.
