Questions & Answers
will this scope hold up on a RWS model 34 springer air rifle? and do you offer or suggest a droop compensator for the RWS 34 Manufacturer Answer

Great scope by Caleb, January 15, 2019
For under $200 this scope cannot be beat. I have it mounted on an AR15 in 6.5 grendel that I use for hunting. Nice clear glass. I like the BDC reticle. To make the most of it, you do need to know the specific ballistics of your load. The one downside...

Scope Review by tjorgen3, January 16, 2017
Have not had a chance to put on rifle yet but seems to be solid and very clear glass. Usually buy Nikon for scopes but had to check out the vortex. Will know more when I go shooting. Plan to use this scope for deer hunting.
