For the price of a Rem Mountain rifle.... I would get a...
Borden action (or custom action of your choice)
Jewel Trigger (or custom trigger of your choice)
Rem takeoff bottom metal, hinged floor plate
Lilja barrel chambered and throated to your specs (or custom barrel of your choice)
B&C Medalist stock, aluminum block bedded - about $250 plus shipping
In a 7 Dakota (or 7mm cartridge of your choice)
.....and have it put together by a smith of your choice.
Why buy factory when you can get custon for about the same price???
