Not Returnable Please note that used items are not returnable.

This is a RedCat 51 is in excellent condition, with clean optics and an unmarked body, with two small exceptions.  The final ring before the back end has some wear and tear; and the previous owner removed the felt from inside the dust cap/bahtinov mask because it was wearing out and getting caught.  This has left the white adhesive there - see the photos.  Obviously, neither of these will affect the optics or use of the scope, but we have discounted the price accordingly to reflect these slight condition issues.  

The scope comes complete, and includes the RedCat handlebar, in its original soft-sided foam-lined case. 

We can ship this item to you.
