Browning Invector Plus DS Shotgun Choke Stainless
Browning Invector Plus DS Shotgun Choke Stainless
The new Browning Invector-DS choke tube system is the biggest leap forward in design since interchangeable choke tubes were introduced. With the Invector-DS, Browning have taken the proven thin wall, muzzle thread choke concept to the next level of shot pattern performance. The exclusive brass alloy band at the base of the tube seals out gas and grit that sneaks between the barrel and tube, making the Invector-DS tubes easy to remove even after extensive shooting. Thin wall construction reduces the flare at the end of the barrel for a sleeker shotgun appearance. Lastly, the Invector-DS offers the most consistent, reliable tightening of any system ever. With all these features, you can't lose with Invector-DS.

In general practice patterns are determined shooting at a 30" circle at 40 yards. Our goal in scaling the tubes is a consistent percentage of the pattern from full choke to cylinder choke. For example a common specification for FULL CHOKE is for 65-75% of the total pellets to be in the 30" circle at 40 yards. IMPROVED MODIFIED would put 55-65% of the pellets in the circle at 40 years. MODIFIED would be about 45-55% and so forth.
To fit the Browning B725 and A5.
- Invector DS chokes ONLY fit Browning shotguns with Invector-DS marked on the barrel (do NOT buy these if you have a shotgun marked Invector Plus (+) or Standard Invector)
- 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 chokes are resistant to steel shot
