Review of Chad's Vortex Viper PST scope. This is an excellent optic for anyone looking for a high quality tactical scope and doesn't want to break the bank. The MOA and MRAD capped models retail for about $499, the new uncapped model runs about $479. The quality and features of this scope are on par with higher end scopes costing much more. Glass is very clear and the 1x setting is very usable, nothing comparable to a holographic optic but very nice regardless.
