Barr Mrad Bbl 308 17 Fluted Conversion Kit$1,586.55
Availability: In Stock
The Barrett MRAD .300 Win Mag conversion kit gives you a straightforward path to add another caliber to your modular rifle platform. This 26-inch fluted barrel conversion kit is built to transform your existing MRAD receiver into a .300 Winchester Magnum shooter—one of the most trusted long-range hunting and precision shooting calibers in North America. If you already run an MRAD and want to expand your capabilities without buying a second rifle, this kit delivers the barrel and essentials you need.
The fluted barrel design reduces weight while maintaining rigidity, a practical advantage whether you're stalking across open country or setting up for extended range sessions. The included Barrett brake helps manage recoil—important when you're working with the .300 Win Mag's substantial report and push. You also get a bolt head, magazine, and a ZCORR anti-corrosion storage bag to keep your new barrel protected during transport and storage. Everything ships in Barrett branded packaging.
One compatibility note: earlier production MRAD rifles may require a separate large-to-small breech conversion kit to accept this barrel. If your receiver is from an earlier build, check your manual or contact support to confirm before ordering. This kit assumes your MRAD is set up to accept it as-is.

This conversion kit is designed for MRAD platforms. However, earlier model MRAD receivers may require a separate large-to-small breech conversion kit to accept this barrel. Check your rifle's production date or manual, or reach out to us with your serial number if you're unsure about compatibility.
You get the 26-inch fluted barrel, a bolt head, a magazine, the Barrett muzzle brake, and a ZCORR anti-corrosion storage bag—everything comes in Barrett branded packaging.
The .300 Win Mag is a proven long-range hunting round, and this barrel gives you the length and profile to make the most of it. The fluted design keeps weight down, which matters on longer treks, while the muzzle brake helps manage recoil on follow-up shots.
Fluting reduces barrel weight without sacrificing the rigidity you need for accuracy. It's a practical choice for hunters and precision shooters who value lighter kit without performance trade-offs.
