Springers are scope killers , only thing worse is a FAL I have killed all brands of scopes on both of these , Leupold , pm2 , ect
only scope I wasnt able to kill was a SWFA
those who are not sure of a fal it is a 7,62 fully or semi auto gas fed rifle which the recoil is both ways does more damage to optics then a 50bmg , If you can survive a FAL with a few hundred rounds you got a battle proven optic
As far as SWFA they are mil spec and use strong ways of securing the lens , where as higher priced optics may use an adhesive which is good for one direction the mil spec is like screwed in and locked in place some eveh have rigs with locktite and secured with set screws I have cut many apart after destroying them to see why . as for SWFA , I only had 2 bad and both were still dead on , one had a bugs leg in side of lens , the other a windage turret became soft and mushy but was easy fix I used brake clan winded turret in cleaned and dried and put a drop of ballistico
l and it was good as new again it was in winter i guess grease got hard ,
