Browning Tube Inv+ Midas Black Lm 20
The Browning Tube Inv+ Midas Black Lm 20 is a long-magnum Invector-Plus choke tube built for shotgunners who want superior pattern control and the convenience of a tool-free swap. This extended tube projects beyond the barrel, making it easy to grab and change in the field without fumbling with recessed flush mounts—a practical upgrade if you're moving away from standard flush-fit Invector-Plus tubes. It's purpose-built for Browning shotguns chambered in Invector-Plus (check your barrel markings to confirm compatibility; these won't work in Standard Invector or Invector-DS shotguns).
Browning engineered the Midas tube to tighten your shot patterns compared to flush Invector-Plus chokes, giving you denser pellet clusters downrange. The stainless steel construction with black oxide finish resists corrosion through wet brush and salt spray, while the laser-etched gold accent band adds a touch of refinement. The geometry is optimized to minimize plastic fouling buildup in the bore, keeping your barrel clean and your patterns consistent through the season.
Whether you're hunting waterfowl, upland birds, or running clay courses, this tube delivers on both form and function—rugged enough for hard use, refined enough to stand out in your shotgun's receiver.

Frequently Asked Questions
Will this tube fit my Browning shotgun?
The Browning Tube Inv+ Midas is designed for Browning shotguns marked Invector-Plus on the barrel. It will not work in shotguns with Standard Invector or Invector-DS markings. Check your barrel before ordering to confirm compatibility.
How does this extended tube differ from flush chokes?
The extended design projects beyond the barrel, making it much easier to grip and swap in the field without special tools. It also produces tighter shot patterns than Browning's flush Invector-Plus choke tubes.
Will this help reduce fouling in my bore?
Yes. The minimum gap geometry and high-resolution RMS finish are designed to reduce plastic buildup in the bore, helping keep your barrel cleaner through extended shooting.
What gauge is this tube?
This is a 20-gauge choke tube.
