Criterion Barrels
Overview
The Criterion Barrels 20" Hbar Contour barrel is designed for precision and reliability, featuring a heavy profile that helps with heat dissipation and overall stability during sustained fire. With a .223 Wylde chamber, this barrel allows for optimal performance with both .223 Remington and 5.56 NATO ammunition, while the 1:8 twist rate effectively stabilizes a wide range of bullet weights. This barrel is typically found in builds that utilize a rifle-length gas system and are chambered in .223 Wylde, making it suitable for both competitive shooting and tactical applications.
