I don't know which model Mcmillan this is but I do know that the LOP is shortened to 12.5". If someone liked the stock they could buy the shim kit that Mcmillan makes and make LOP whatever they wanted. Stock is in great condition and it was professionally bedded by a gunsmith. Accepts standard tikka bottom metal or the red snake DBM bottom metal which is what was in it when I bought the rifle. I'll take $450 for it plus shipping cost. Thanks
