Product Information

The 6x45mm (6mm-223 Remington) cartridge offers excellent penetration, a little lower velocity and moderate effect on small game and varmints. The 6mm bullet tends to have a superior ballistic coefficient in comparison to 224 diameter bullets which in turn improves accuracy. This barrel is manufactured from 416 stainless steel and features a threaded muzzle.
