Check out all of the pictures, for the condition. We are selling this rifle as you see it, no magazine with the gun.

 

Sellers Note:

We rate this rifle at 97% condition! The bore looks great, with strong rifling. The gun is however used and has wear from firing behind the chamber/action and some scratch here and there on the finish. We are selling this gun for a good price, but fair to the condition!
