New Frontier Ar45/10 Match Bbl - 4" 1:16 10mm Auto Black

The New Frontier AR45/10 Match Bbl in 4" 1:16 10mm Auto is a precision barrel engineered for shooters who demand accuracy and reliability in the demanding 10mm Auto cartridge. Purpose-built for AR-platform rifles and pistol caliber carbines (PCCs), this match-grade barrel serves law enforcement, competitive shooters, and serious civilian enthusiasts who rely on tack-driving accuracy at defensive and tactical distances. The 4-inch length balances velocity retention with maneuverability, making it ideal for short-barreled configurations that don't compromise on performance.

Manufactured by New Frontier Armory, a respected builder of precision AR components, this barrel features a 1:16 twist rate optimized for 10mm Auto ammunition across the full spectrum of bullet weights and velocities. The match-grade profile ensures consistent accuracy by reducing harmonic vibration and maintaining bore straightness under sustained fire—critical for both duty use and competition. The black Nitride finish provides superior corrosion resistance and durability, handling harsh training environments, duty conditions, and extended storage without degradation. Weighing just 0.6 lbs, the compact design minimizes overall system weight while maintaining the structural integrity required for centerfire rifle caliber performance.

This barrel is ideal for AR45/10 builds and other 10mm AR platforms that prioritize accuracy and reliability. Installation requires basic gunsmithing knowledge or professional assistance to ensure proper headspace and barrel extension compatibility. The 4-inch configuration works best in pistol-length or carbine-length gas systems, delivering optimal performance when paired with quality ammunition and proven AR components. Whether you're building a duty rifle, competition platform, or home defense carbine, this match barrel transforms your AR into a precision instrument capable of repeatable accuracy at combat-effective ranges.
