Criterion Barrels
Overview
The Criterion Barrels Inc 20" Hybrid Contour barrel features a 20-inch length with an M4 profile, designed to accommodate the .223 Wylde caliber, which allows for safe chambering of both .223 Remington and 5.56 NATO cartridges. With a rifle-length gas system and a .750 gas block diameter, this barrel promotes reliable cycling while maintaining accuracy, aided by a 1:8 twist rate that stabilizes a variety of bullet weights. This barrel is commonly found in builds that utilize a rifle-length gas system and favor the versatility of the .223 Wylde caliber.
