Bergara Barrel AR-15 5.56x45mm NATO Heavy Contour 1 in 9" Twist 16" Nitride Finished Chrome Moly Black
This barrel has been finished inside and out with a protective black nitride treatment that surface-hardens the metal, extending barrel service life by reducing friction in the bore and lessening bore surface wear. The salt bath nitride finishing process deposits an extremely hard, slick surface on steel that resists carbon adhesion and increases corrosion resistance, making for easier cleaning and maintenance. Nitriding converts the steel's surface without any build-up, retaining all of the benefits of traditional chrome lining without suffering the accuracy degradation commonly encountered with chrome due to its uneven application inside the barrel's bore.
This 16" AR-15 barrel features a true 5.56x45mm NATO chamber for use with both commercial and military surplus ammunition, while its 1 in 9" twist rifling is capable of stabilizing light to medium weight projectiles of up to about 69 grains. It comes equipped with a heavy carbine profile that is .980" diameter under the handguard and steps down to .744" diameter forward of the gas block. The muzzle is topped off with an 11 degree target crown and 1/2"-28 threading for the addition of a flash hider, muzzle brake or sound suppressor. This barrel is a great choice for shooters that can tolerate a little extra weight out front in return for the increased rate of fire that can be maintained before allowing the rifle time to cool. Barrel is fully chambered and includes a pre-installed barrel extension with M4 feed ramps and locator pin.
