Rosco Manufacturing K9 5.56 AR-15 Barrel - Intermediate - Tapered - 16"

The Rosco Manufacturing K9 is a 16-inch barrel chambered in 5.56 NATO, designed for AR-15 platforms. This intermediate-length gas system barrel features an optimized gas port for reliable function with or without a suppressor.

Features:

• 16" barrel, continuous taper profile
• Chambered in 5.56 NATO, 1:7 twist
• 416R stainless steel construction
• Nitride finish
• Intermediate-length gas system, gas tube included
• .750" gas seat diameter
• Threaded 1/2x28
• Recessed target crown
• 34.5 oz weight

The continuous taper profile prioritizes heat dissipation during heavy use, and shifting weight toward the rear of the barrel improves balance and handling, especially with front-mounted attachments. The updated target crown is inherited from Rosco's Purebred series for improved harmonics, fit, and finish.

Rosco Manufacturing produces every barrel entirely in-house from raw steel, controlling every step of the process. Based in Central Falls, Rhode Island, every component is 100% made in America, by Americans.
