1. Aimpoint Micro H-2 

 

 

 

the Aimpoint Micro H-2 is exactly the sort of optic to consider. It’s a compact, 1× reflex sight engineered around long life, unsurprising reliability, and excellent dot clarity — everything pellet shooters appreciate when they want quick sight acquisition without adding bulk or fiddly controls.

The Micro H-2 uses an advanced objective-lens system that produces a clean, well-shaped 2 MOA red dot that is effectively parallax-free at typical pellet-rifle ranges. That small dot size makes it easy to pick tight POIs (pellet groups and small targets) while still allowing very fast target acquisition for plinking or pest control.

Durability is a headline feature: the housing is a hard-anodized aluminum alloy with recessed lenses and protective design elements. Aimpoint rates the Micro H-2 submersible to 15 feet, and the recessed optics plus included flip-up covers keep the glass and electronics protected from rain, mud, and knocks — reassuring for field use or wet conditions.
