The Barrett MRAD Barrel Conversion Kit in .300 PRC with a 26-inch stainless fluted barrel lets an existing MRAD owner add a second caliber without buying another rifle (brand part no. 18431). Barrett builds the kit around a 1-in-8 twist barrel threaded 5/8×24 and fitted with a Barrett brake, so it arrives ready to shoot at long range. It comes with the barrel, a bolt head and a magazine, which covers the parts that change when you swap chamberings. The package travels in a carrying case with an anti-corrosion bag to protect the bore between swaps. For a precision shooter who wants the reach of .300 PRC on a platform they already trust, Barrett gives a factory route to it.

Key Specifications

• The chambering is .300 PRC, a long-range magnum cartridge that suits extended precision and hunting work.
• Barrel length is 26 inches, long enough to give the cartridge full velocity.
• Rifling twist is 1-in-8, which stabilizes the heavier bullets this cartridge is known for.
• The barrel is stainless steel, which resists corrosion and holds accuracy through long strings.
• The barrel is fluted, removing weight and adding surface area to help it shed heat.
• The muzzle is threaded 5/8×24, the standard pattern for brakes and many suppressor mounts.
• A Barrett brake is included on the muzzle, which tames recoil from the magnum round.
• A bolt head is included, so the bolt is ready for the new cartridge.
• A magazine is included, saving you from hunting down a matching one.
• The kit ships with a carrying case and an anti-corrosion bag, which keep the barrel protected in storage and travel.
