The UltraDot Gen 1 has been a tried and true workhorse for the last thirty years, but at the request of UltraDot's loyal shooters the new generation was born. Hard to improve on such a reliable and consistent companion to your firearm, but they somehow got more precise with the 2 MOA dot. Additional features include a compact and lightweight design, rugged recoil resistance, and an 11 position adjustable brightness rheostat.
