Multi-purpose, screw-in choke tube gives excellent performance with a variety of law enforcement shotgun ammunition, including rifled slugs, buckshot, and breaching rounds. Direct replacement for popular factory screw-in tubes, so it eliminates the inconvenience of having to change the muzzle device for specific applications. Sharply crenelated muzzle provides the proper stand-off distance and secure grip on the surface for use as a breaching device. Won’t interfere with performance of buckshot, and preserves the downrange accuracy of slugs. Precision machined from carbon steel, with a knurled surface for easy installation/removal, and a wear-resistant, non-glare black oxide finish.
