Browning Standard Invector 12 Gauge Cylinder Flush 17-4 Stainless Choke Tube

The Browning Standard Invector choke tube is a factory flush-mount replacement for Browning shotguns threaded for the original Invector or Standard Invector choke system. This single tube is cut for 12 Gauge with a Cylinder constriction, delivering an open .000" bore for the widest, most uniform pattern Browning offers in the Standard Invector line.

Machined from 17-4 stainless steel with a polished stainless finish, the tube is built to resist corrosion and withstand years of repeated use in the field or at the range. Cylinder constriction is well suited to close-range work and is recommended for 20-yard patterning, making this a strong choice for multi-purpose applications including short-range hunting, slug use, and open-cylinder patterning. The tube is non-ported and approved for use with steel, lead, and non-toxic shot loads.

Standard Invector tubes fit only shotguns marked Invector or Standard Invector. They do not fit Invector-Plus (+) or Invector-DS threaded barrels. Confirm your barrel is marked Standard Invector before installation. One choke tube is included.
