Weekend Warrior Shop International recommends the Sightmark Ultra Shot R Spec Red Dot for airsoft and paintball use. But if you need a more affordable version, you can check the sister brand of Sightmark, Firefield as the products are more aimed at the airsoft market.

The Sightmark Ultra Shot R-Spec Reflex Sight has a long battery life, a wide-angle lens system, 4 illuminated reticle options, and parallax correction. It is shockproof, weather-resistant, and recoil rated up to .50 BMG. It has 1 MOA windage and elevation adjustments, a low battery indicator, digital switch controls, and a quick-detach picatinny mount. It comes with adjustment tools, a CR123A battery, an operation manual, and a neoprene cover.
