Iver Johnson 410 Bore Improved Modified Mobil Choke Tube

The Iver Johnson 410 Bore Improved Modified Mobil Choke Tube is an extended, stainless steel choke designed for shotguns chambered in .410 Bore that use the Beretta/Benelli Mobil choke thread pattern. The Improved Modified constriction sits between Modified and Full in the choke spectrum, offering a versatile balance of pattern density and spread for a variety of shotgun applications.

Machined from stainless steel and finished in black, this choke is built to resist corrosion through regular use. The extended body design provides easier installation and removal with hand tools and offers a visible reference point at the muzzle. Compact 0.70" x 0.70" x 2.00" dimensions keep the tube light and unobtrusive at the end of the barrel, while the precision-bored Improved Modified constriction delivers consistent shot patterns.

This tube installs directly into any .410 Bore shotgun equipped with the Beretta/Benelli Mobil choke system. Whether patterning a hunting shotgun or tuning a clay gun, this choke provides reliable constriction and steady performance in a compact, corrosion-resistant package.
