I have a McMillan stock that has been bedded for the Colt Sauer. Had it on a 300 that was never taken hunting. It is black and in 99% new condition. It will also fit the Sauer 90 rifles but the floor plate on some of them isn't as wide in the front as the Colt Sauer's floor plate. If it's for hunting it'll work great. If you want a perfect fit this stock is not for you. I do know it works on the Colt Sauer 7 mag and 300 Wby mag among a host of others. Pretty sure all the way up to 458 Win - not positive but don't see why it wouldn't. Will take $400.00 including shipping for the stock in the USA.
