The Rosco Manufacturing BL-105-HB-300BLK-7-P Bloodline 300 Blackout 10.50" Nitride 4150 CMV Barrel is a heavy-profile, threaded AR-15 barrel built to maximize performance with the 300 AAC Blackout cartridge. Crafted from durable 4150 CMV steel and finished in black nitride, it offers a balance of longevity, corrosion resistance, and consistent accuracy, especially when paired with a suppressor.
This 10.5" barrel is ideal for SBR and pistol builds that need reliable function with both subsonic and supersonic 300 Blackout loads. The pistol-length gas system and 1:7 twist rate are tuned for smooth cycling and stable bullet flight, making it well suited for range use, training, and general-purpose carbine setups that demand compact handling. Rosco Manufacturing’s attention to detail and commitment to practical performance are evident in the Bloodline series, delivering a barrel that reflects thoughtful engineering and solid craftsmanship.
