wyzeguy9--- yes I picked it up its at the gunsmith now he has to work on the stock to get it fit its the only detachable mag I think for the 300 ultra mag not sure though sure did get it for good price $100.00 said new it was $220.00 he only had it for 2 months sure am glad he sold that rifle.
Thats the rolls royce of detachables for sure and made of 17-4 SS to boot as well as teflon coated.. Heck Remington Bottom metal can run from 80 dollars(Ebay) to 150 dollars (Brownell) I say you got a heck of a deal.
