300 Aac Blackout 1-7 Twist 11.3'' Pistol Barrel

The 300 AAC Blackout 1-7 Twist 11.3'' Pistol Barrel by Wilson Combat is purpose-built for short-barreled rifle (SBR) and pistol platform shooters who demand precision and reliability in a compact configuration. Designed for law enforcement, military, and civilian tactical operators, this barrel excels in suppressed and unsuppressed applications where barrel length is constrained but ballistic performance cannot be compromised. The 300 Blackout cartridge has become the standard for specialized operations requiring subsonic or supersonic capability in confined spaces, making a properly engineered barrel critical to mission success.

Wilson Combat's engineering delivers a 1-7 twist rate that stabilizes both lightweight 110-grain and heavy 220-grain subsonic projectiles with consistent accuracy—a critical advantage over faster or slower twist rates that force ammunition compromises. The 11.3-inch length balances muzzle velocity retention with overall package maneuverability; this dimension is the professional choice for suppressed work, where the additional dwell time enhances reliability and sound signature control compared to shorter barrels. Manufactured to exacting tolerances, the barrel features premium steel construction and precise chamber geometry to minimize pressure spikes and maximize consistency across diverse ammunition loads, a hallmark of Wilson Combat's military-contract heritage.

This barrel is ideal for builders assembling AR pistols, registered short-barreled rifles, or precision tactical platforms in 300 Blackout. Installation requires a correctly headspaced upper receiver and attention to gas system tuning when suppressed—experienced gunsmiths and armament professionals should handle assembly to ensure reliability and safety. Compatibility extends across standard AR-15 platforms with proper upper receivers; the barrel threads accept industry-standard suppressors (typically 5/8x24), making it the preferred choice for operators who refuse to compromise on accuracy or function in specialized operational roles.
