Browning Standard Invector 410 Bore Modified Flush Choke Tube - 17-4 Stainless

The Browning Standard Invector 410 Bore Modified choke tube is a flush-fit replacement choke designed for Browning and Browning-pattern shotguns chambered in .410 bore using the original Standard Invector choke system. It is precision machined from highly polished 17-4 stainless steel and set to the industry-standard Modified constriction of .012".

Standard Invector tubes produce patterns with excellent uniform densities, making this Modified choke a versatile choice for upland hunting, small-game work, and general multi-purpose shotgunning out to roughly 45 yards. The tube is approved for use with steel, lead, and non-toxic shot, so it pairs safely with a wide range of modern .410 bore shotshell loads. It is a non-ported flush design that sits flush with the muzzle when properly seated.

Tube length is approximately 1.875" with a weight of roughly 0.4 oz. One choke tube is included. Installation is simple hand-threading into a Standard Invector-compatible choke seat - no special tools required; just follow standard choke-tube practices (a light coating of oil, hand-tight, and verify the tube is seated against the barrel).

This is a brand-new, factory Browning accessory (part number 1130277) and is the correct replacement tube for older Browning shotguns and other manufacturers' guns equipped with the original Standard Invector choke system. It is not designed for the longer Invector-Plus or Invector-DS systems.
