Very dissapointed - Leupold VX6 1-6x24 CDS Riflescope w/ FireDot Illuminated Reticle

Purchesed this scope for my Mega Arms AR-15 build. Scope seemed awsome out of the box and during the fist trip to the range. Only put a total of 60 Rounds of 556 through the gun with the scope on. All was well untill the next time I looked through the scope. Noticed a large piece of black debris on the inside of the the scope. Leuopld would not pay for shipping and it cost a premium to ship this since it was such an expensive item. Took over a mounth to get it back and when I did the turrets were lose and marred up and the scope was scratched from the repairs. It had to be compleatly dissasempled and cleaned on the inside. Poor quality control and poor warrenty service for a priemium scope. This was my first and last Leupold scope I will have purchased. Also the magnification selector ring is very stiff nearly impossible to manipulate when it is cold with gloved hands, meaning you have to purches a MGM switchview or simmilar product. Also lense covers are not readily aviailble. I was hoping to purchase tenebraex killflash lense cover, hover they are not availible for this unit. If I was to do it again I would have whent whith a vortex Razor.
