One Horse 300 Blackout AR-15 Barrel - Pistol Length - Medium - 10.5"

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.

The .300 Blackout was designed for exactly this -- a 10.5-inch barrel that cycles both supersonic and subsonic loads reliably, whether run suppressed or unsuppressed. The One Horse 10.5-inch .300 BLK barrel brings pistol-length gas, black nitride, and mil-spec 4150 construction to compact builds.

Features:

• 10.5" 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 suppressor compatibility
• Made in the USA

The pistol-length gas system is specifically tuned for .300 Blackout in a short barrel, providing reliable cycling across the full spectrum of loads from 110-grain supersonic to 220-grain subsonic ammunition. The 1:7 twist rate reliably stabilizes the heaviest .300 BLK subsonic projectiles, critical for suppressed builds.
