I have a set of barrels for the 2400 and 2 of them are valmet
1 is a lion 12/12--it fits but I had to re-do the forearm attachment hook to fit the savage 2400 forearm
The other has been described to me as a valmet 312 in 22 savage HP over 12--I bought the whole gun --it has 2 triggers and all my 2400 barrels (308,222,12/12 and 20/20)fit it and vice versa to my 2400 reciever--which is actually a 330 receiver
