Helpful Positive Review A great Scope mount by Steve, December 8, 2017
Easy to setup. Locks down rock solid. Excellent workmanship, made in the USA. I use one with my Vortex Viper PST scope. If you own a 30mm this is a great addition to your setup. When it's installed I still have room for my backup iron sights.
