Ar-15 Modern Series Barrels .300 Blackout - Ar-15 Pistol Length 9 Barrel .300 Blackout

Specifications

Pros

• .300 Blackout chambering for compatibility with this caliber platform
• 6-inch Modern Series barrel for compact pistol-length builds
• Machined from 4150 Chrome Moly Vanadium steel
• QPQ corrosion resistant finish for added surface protection
• QPQ coated M4 feed ramp extension
• .750-inch gas block journal and 1:7 twist rate

Considerations & Trade-offs

• This is a 6 inch barrel, so it is intended for compact .300 Blackout builds rather than longer rifle configurations.
• The product is subject to NFA/ATF rules; compatibility depends on the receiver setup, and possession with a non-NFA lower receiver is prohibited except when installed on a pistol configuration firearm.
• The .750" gas block journal and 1:7 twist rate are fixed specifications, so they should be matched to the rest of the build before purchase.
• The QPQ finish and QPQ coated M4 feed ramp extension are part of the design, but the listing does not provide additional performance details beyond those features.
