The Standard Invector choke tube system is one of the most popular chokes for early Browning and Winchester shotguns. These choke tubes can be found in just about every diameter. Most choke manufacturers offer Invector choke tubes for waterfowl and turkey hunting.
Shotguns and chokes that are compatible with Invector will typically have “Invector” or “INV” written on them. Standard Invector choke systems can be found on certain Browning, Winchester, and Mossberg shotguns.
