The Barrett 308 Win 17" Black Carbon Fiber barrel conversion kit brings precision-focused performance to the MRAD platform in a compact, lightweight package. This 17-inch carbon fiber barrel is chambered in .308 Winchester / 7.62x51mm and features a threaded muzzle with 5/8"x24 pattern, ready for brakes or suppressors. Included in the kit are a magazine, breech components, and a padded Barrett-branded carry sleeve to keep the barrel protected when not installed.

This conversion kit is ideal for shooters who want to switch their MRAD to .308 Win for range work, training, or precision target shooting while keeping overall rifle weight manageable. The 1:10" twist rate is optimized for common .308 bullet weights, supporting consistent accuracy at distance. Barrett’s attention to detail and proven craftsmanship in their MRAD system ensures reliable fit, repeatable zero, and long-term durability with every barrel change.
