Criterion Barrels 10.5" .223 Wylde Hybrid Phosphate/Chrome-Lined Carbine Length Barrel 1:8 Twist

The Criterion AR-15 Hybrid barrel is designed for extreme accuracy without the added weight that a typical HBAR contour has. These barrels are chambered in .223 Wylde with a 1:8 button rifled twist rate to squeeze out every bit of accuracy possible. The chrome lining process makes the bore extremely hard to withstand the constant friction of a high-powered round passing through resulting in a long barrel life. The bore is then hand-lapped to make sure the lands and grooves are as smooth and consistent as possible to further ensure you are getting the most accuracy as possible. This 10.5 inch barrel is built with a carbine length gas system and an optimized gas port size to ensure reliable function with both 5.56 and .223 ammunition. If you are building a new AR-15 and accuracy and reliability are at the top of your checklist, then check out the Criterion Hybrid line of barrels.Features:10.5" barrel with .223 Wylde chamberHybrid barrel contourChrome lined and hand lapped bore1:8 button rifled twistCarbine length gas system with .750" diameterDimpled beneath the gas portWeight: 1.35 lbsThis Criterion AR-15 barrel also features a dimple beneath the gas port for set screw style gas blocks.
