BRO T-WRENCH 28GA Standard Invector Shotgun Choke Tube Wrench

The Black Rain Ordnance T-Wrench for 28-gauge Standard Invector choke tubes is a purpose-built tool for shotgunners who need reliable access to their choke adjustments. If you run Browning Standard Invector tubes on your 28-gauge shotgun, this wrench fits the wrench slots on your chokes—giving you the grip and leverage needed to remove and reinstall tubes safely, whether you're at home, in the field, or at the range.

Choke tube wrenches are often overlooked until you need one. Many extended chokes can be finger-removed without trouble, but standard tubes rely on those side-mounted wrench slots that require the correct gauge tool to access. Using the wrong wrench—or trying to force a slot-less approach—risks damaging the choke or your shotgun's threads. Black Rain Ordnance built this wrench to fit Standard Invector geometry precisely, so you get solid contact every time.

At just 3.2 ounces, it's light enough to toss in a range bag or shotgun case without adding bulk. Keep one on hand if you're the type who likes to dial in your pattern between duck blinds or experiment with different constrictions across your shot string. Whether you're a competitive clay shooter tweaking tubes between events or a hunter matching chokes to your load, having the right tool means faster swaps and confidence in your setup.

Frequently Asked Questions

Will this wrench work with Invector-Plus or Invector-DS chokes?

No. This wrench is designed specifically for Standard Invector tubes. Invector-Plus and Invector-DS have different choke designs and require their own corresponding wrenches. Using the wrong wrench can damage the choke or shotgun threads, so verify your choke type before purchasing.

What gauge shotgun is this wrench for?

This is a 28-gauge choke tube wrench. It will not fit 12-gauge, 20-gauge, or other gauge tubes, as each gauge has different wrench slot dimensions.

Can I remove Standard Invector chokes by hand?

Many extended chokes can be finger-removed, but most Standard Invector tubes have the wrench slots hidden on the sides. This tool gives you the leverage and grip to access those slots and safely remove and reinstall your chokes without risk of cross-threading or damage.
