The Barrett MRAD SMR .300 Norma Magnum rifle in Flat Dark Earth Cerakote (Barrett part no. 18509) is the Single Mission Rifle version of the MRAD, set from the factory in one caliber instead of using interchangeable barrels. Barrett says the SMR keeps about 90 percent parts commonality with the standard MRAD in a simpler package, trimming nearly 2.5 pounds and an inch of overall length. It pairs a free-float 26-inch barrel with a fixed stock, an adjustable cheek piece and a 21.75-inch top rail. That makes it a purpose-built long-range rifle for hunters and precision shooters who do not need to swap barrels.
