just some thing i have noted reference the arken scope, my first arken became faulty so i returned it to optics warehouse and after quite a few weeks a replacement was sent to me, straight out of the box the lenses had oil/contamination on the inside of the lenses making the scope unusable so again returned to optics warehouse another long wait and a third scope was sent to me, this one functions and works as it should BUT NOTE the lense quality is not as good as the original scope i purchased .the quality of the glass appears to me to be of a lesser quality. maybe arken has changed their suppliers but the quality of the scope seems to be less than the original arken i purchased. perhaps another example of give your first buyers a good scope but as sales improve drop the standards and hoped no one notices ,more money in the sellers pockets .just my opinion but arken wont be on my recommendation list.
