I have a Trijicon Accupower 5-50x56mm SFP ,I was told its the same thing as the Ten Mile. Came with lots of goodies including an owners manual . I also have a Athlon Cronus 4.5-29x56mm FFP. It came with a Box and a scope and that's it, had to down load the owners manual .Looking back I wish I bought the Trijicon Accupower 4.5-30x56mm FFP instead of the 5-50x56mm . The glass to my 63 year old corrected vision eyes,the color is slightly better with Athlon ,but other than that the glass is equal . Also have a Zeiss V6 and glass is significantly better than both. Brought out my Sightron S111 6-24x50mm and its glass wasn't far behind the Trijicon or the Athlon Cronus .
Yeah 5-50x is a HUGE ask for any scope to perform well. The 5-50 has good glass, but definitely not as good as the 4.5-30.
