Black Rain Ordnance
The BRO TUBE 12GA Invector DS Extended Full Choke Tube from Black Rain Ordnance is a purpose-built choke tube designed specifically for Browning shotguns with Invector-DS barrels. The extended design places the choke body beyond the muzzle, making it easier to grip and remove while delivering the tight, consistent patterns serious shooters demand. If you're running a Browning pump or semi-auto and want to tighten your shot grouping for hunting or sport shooting, this full choke option gives you the geometry to do it.
What sets the BRO TUBE apart is its engineering approach to the seal. A proprietary differential banded gas seal sits at the interface between the choke and its seat in the bore, managing pressure and residue buildup so the tube stays clean and removes smoothly every time. An integrated spring suspension holds that seal tight while allowing controlled expansion against the barrel wall—no binding, no fighting with a stuck choke. The result is a flawless transition for the shot column and the reliable, repeatable patterns you need when accuracy matters.
Built from nickel chrome moly with stainless steel finish and chrome-lined pockets, the BRO TUBE is made to handle regular use and the elements. At 4.8 ounces, it's substantial without being cumbersome. The full choke constriction delivers 70–75% pattern density, making it ideal for longer shots and tighter grouping at distance.

The BRO TUBE 12GA Extended Full is designed for Browning shotguns with Invector-DS barrels only. Check your barrel marking to confirm Invector-DS compatibility before ordering.
This is a full choke tube with a pattern density of 70–75%, making it ideal for extended-range hunting and tight, consistent grouping at distance.
The extended design makes the choke easier to grip and remove without tools, and the geometry allows for the optimized taper and seal design that delivers consistent, tight patterns.
A proprietary differential banded gas seal manages pressure at the interface between the choke and the barrel bore, preventing residue buildup while an integrated spring suspension allows controlled expansion for a perfect, smooth fit.
