One Horse 300 Blackout AR-15 Barrel - Pistol Length - Medium - 7.5"

Note: this barrel is under 16 inches in length. The National Firearms Act regulates configurations assembled with barrels this short -- know the NFA laws in your state before purchasing.

As compact as .300 Blackout gets in an AR platform. The One Horse 7.5-inch .300 BLK barrel delivers pistol-length gas, black nitride finish, and mil-spec 4150 construction in the shortest practical barrel length for the cartridge.

Features:

• 7.5" barrel, Medium profile
• Chambered in .300 AAC Blackout, 1:7 twist
• 4150 steel construction
• Black nitride finish
• Pistol-length gas system
• .750" gas seat diameter
• Threaded 5/8x24, for direct-thread suppressor attachment
• Made in the USA

The pistol-length gas system is tuned for reliable cycling in a 7.5-inch .300 BLK barrel, and the 1:7 twist rate handles the full range of .300 BLK projectile weights reliably, including the 200-to-240-grain subsonic loads that drive most suppressed .300 BLK builds.
