The Aimpoint Comp M4 impresses as a top-tier red dot sight. Its rugged aluminum build ensures outstanding durability, making it a trusty companion for any challenging situation. What really sets it apart is the phenomenal battery life, lasting over 80,000 hours on a single AA battery, a feature we personally find incredibly convenient. 

No more wondering when you last switched batteries!

The optical performance doesn’t disappoint either, with a crisp 2 MOA dot that aids in swift and accurate target acquisition. Although it’s a bit on the expensive side, for us, the Comp M4 is worth every penny for its unmatched performance and reliability. It’s an investment we’d recommend for any serious shooter looking for a long-lasting, high-quality optic.

What Customers Say

After reviewing a lot of other red dots, scopes, and various optics the Aimpoints are still an unbelievably reliable and proven optic. I had mine on for years and the battery never went out. At 100 yards I was able to shoot 2-inch groups with slow fire. I’m considering a couple other optics solutions currently as I shop for my new AR, but for the price and track record, I think the PRO is a solid choice. Bill B.
