Product Description

This Rosco 10.5" 9MM Bloodline Barrel is designed to be the ideal addition to any SBR or pistol build. ALL NFA RULES APPLY! Rosco 9MM barrels are made to meet the needs of modern carbine shooters. Rosco is significantly different from your daddy's Sporter AR, and those specs just won't suffice anymore. From properly managing dwell times for SBRs, to running suppressed, or setting up a balanced patrol carbine, Rosco has incorporated your needs into its design. Rosco has achieved this by selecting the right twist rates, gas port sizes, and barrel materials suitable for each barrel.
