This is a must have for the pst scope - Vortex Switchview Throw Lever for Viper PST and Viper HS Rifle Scopes

When I purchased the Vortex Viper PST 4-16x50 the one thing I disliked about the scope was the adjustment of the magnifier. It's very hard to turn. I just happen to come across the switchview throw lever which at the time I did not know the purpose of this item. I began to read the spec regarding the lever and decided to give it a try. Wow!!! after installing the lever this made a world of a difference in the adjustment of the magnifier. If you own a Vortex PST scope this is a must have because it makes the magnifier adjustment really easy.
