Rosco K9 11.5" Barrel System
The Rosco K9 represents a thoughtful evolution in short-barrel rifle design. This 11.5-inch barrel splits the difference between carbine and mid-length gas systems, delivering a patrol-length gas system that offers superior smoothness and reliability compared to traditional carbine-length configurations.
Key Features
Gas System Design
- Proprietary patrol-length gas system optimized for both suppressed and unsuppressed operation
- Carefully tuned gas port for reliable cycling under all conditions
- Superior balance between recoil impulse and bolt carrier velocity
Barrel Profile & Construction
- Continuous taper profile efficiently dissipates heat during sustained fire
- Weight distribution shifted toward the rear of the barrel for improved rifle balance
- Nitride stainless steel construction for durability and corrosion resistance
- Updated target crown for improved harmonics and fit
Handling & Performance
- Shorter overall length ideal for close-quarters work and vehicle operations
- Better weight distribution creates a more naturally pointing rifle
- Modern attachment points on the barrel remain uncompromised
- Refined finish and attention to detail throughout
The K9 is purpose-built for shooters who demand reliability, balance, and precision in a compact package.
