Rosco Bl Bbl 5.5" 9mm 1/10

The Rosco Bl Bbl 5.5" 9mm 1/10 is designed for operators seeking an ultra-compact barrel suitable for pistol caliber carbines or large-format pistols. This barrel is particularly useful for those building suppressed platforms where minimizing total system length is essential for close-quarters battle (CQB) or covert carry.

With a length of 5.5 inches, this barrel provides adequate dwell time for reliable cycling while allowing for integrated suppressor setups. It features a 1/10 twist rate, which is effective for stabilizing common 9mm projectile weights. The specialized feed ramp geometry is designed to ensure consistent feeding from various magazine types, addressing a common failure point in short-barreled PCC builds.

Ideal for home defense or specialized sub-gun applications, the Rosco Bl Bbl 5.5" 9mm 1/10 offers the reliability needed for critical situations. It is compatible with standard 9mm AR-style uppers, making it an excellent choice for those looking to enhance their custom builds. This barrel allows for maneuverability in tight spaces while maintaining performance.
