Browning 12 Gauge Invector-DS™ Flush Choke Tube Skeet

The next generation choke tube. These choke tubes fit flush with the end of the barrel but are longer than competitors’ tubes. Proprietary differential banded gas seal eliminates residue build up and makes chokes easy to remove and install.

Integrated spring suspension holds the seal tight, yet allows expansion against the barrel wall for a perfect fit and a smooth transition for the shot column entering the choke
Gas is controlled at the interface between choke and where it seats in the bore
From skeet to full choke, patterns tighten consistently and reliably
Invector-DS tubes fit only Browning shotguns designed for Invector-DS and are not for use in shotguns showing Invector-Plus or Standard Invector on the barrel(s).

The newest and most advanced Browning choke tube system.

Invector-DS choke tubes fit only Browning shotguns with Invector-DS marked on the barrel(s).
DO NOT buy these if your shotgun is marked Invector, Standard Invector or Invector-Plus (+).
The choke constriction technologies found on Invector-DS choke tubes improve pattern performance beyond what was previously thought possible.
Invector-DS choke tubes are much longer than other Browning choke tubes and have threads on the muzzle end of the tube. They also feature a bronze seal at the base of the tube that helps prevent fouling from being forced into the gap between the barrel and the choke tube, making the tube difficult to remove.
