Weight & Profile:
The Henry .22 is a lightweight rifle — stick with micro or mini red dots (under 6 oz) to preserve handling.Dot Size:
For precision target shooting, a 2 MOA dot works best. For fast plinking, a 3–4 MOA is ideal.Mounting Compatibility:
Many Henrys have 3/8" dovetail grooves, not Picatinny rails. You’ll likely need a dovetail-to-Picatinny adapter for most optics.Battery Life:
Rimfire rifles aren’t usually “go-bags,” so long battery life (10,000–50,000 hrs) means less hassle.Durability vs. Cost:
Since the Henry .22 produces minimal recoil, you don’t need an optic rated for 5.56 NATO — meaning more affordable choices like the Holosun 403B or Burris FastFire 3 will last for years.

Here’s a quick rundown of my favorite optics that complement the Henry .22 platform:
Each of these optics offers a unique mix of precision, battery life, and compact form — ideal for rimfire rifles like the Henry 22.
1. Burris FastFire 3
The Burris FastFire 3 has become a go-to option for shooters who want a lightweight, highly reliable reflex sight for rimfire rifles. Its crisp 3 MOA dot is perfect for the moderate distances a Henry 22 is typically used for — whether plinking cans or dispatching varmints.

Mounted on a Henry Frontier, the Romeo5’s MOTAC feature was a game changer. The optic powered on instantly when I shouldered the rifle, making it perfect for quick plinking sessions.
