ORIGINAL: Gut Check
if you want the best go with spot hogg. capable of being sighted in using 2nd and 3rd axis. also micro adjustable. pins aren't extremely bright but you can buy aftermarket fiber optics. you won't find a better constructed sight IMO.
I bought a light for my Hogg it as I like the small pins. No need to worry about pin brightness anymore as they came out with the Hogg wrap on the new ones.
