Chambered for 5.56x45 NATO, originally derived from .223 Remington, 5.56 NATO is the standardized and most popular cartridge developed for the AR-15 platform. Utilizing a .22 Caliber projectile, the low mass, high-velocity cartridge allows superior weapon handling with manageable recoil and high accuracy. With a wide variety of ammunition choices on the market, 5.56 NATO chambered AR-15s are 'multi-caliber' and can reliably fire both 5.56x45 NATO and .223 Remington cartridges.
This 10.5-inch barrel operates on a carbine gas system and is chambered for 5.56. It has a 1:7 twist rate which works well to stabilize heavier projectiles. It is made from high-strength material with a nitride finish to ensure it is durable, reliable, and incredibly strong.
