The CVLIFE 3-9×40 Optics R4 Reticle Crosshair Air Sniper Hunting Rifle Scope with Free Mount includes a Special inner and outer structure to control the interaction between the inner and outer tubes of the scope, which provides long lasting reliability in these interaction and ensures the reticle would not rotate when adjusting. This smart design makes the scope shockproof and provides more precise windage and elevation adjustment.
Built on an ultra strong 1 inch machined-aluminum tube. Completely sealed and 100% nitrogen filled makes it fog and rain proof. This tactical scope could be used under any weather condition.
