Today, I traded into an interesting rifle. It appears to be a mid to late 90's Remington Mountain Rifle DM in .270 Win. The kicker is that the barrel appears to be factory, is a factory Remington Barrel and is 24" long. I dont recall a standard chambering in 24" barrel on the early Mountain Rifles. Any thoughts on if this is just a Mountain Rifle, or could you order a custom barrel length from the Custom Shop?
