Great scope - Nikon 3-9x50 ProStaff Waterproof Rifle Scopes

Got this scope for my son's Ruger American in 270. one thing to be sure is to measure the length of the scope as it would not fit was to short. I turned the front base around and it worked. there wasn't much room to move the scope for eye relief. It was good for his eye as it was thanks to the 50 mm. Used Leopold medium rings and it was down as far as it could go . Had to sand down the scope cover next to the barrel for it to go on. So be careful to measure the length of scope and the distance between the bases.
Great scope, good price from Optic Planet. Son it happy with it.
