BRO TUBE 20GA INV Midas Modified Choke Tube

The Black Rain Ordnance BRO TUBE 20GA INV Midas Modified choke tube is built for shotgunners who demand precision and reliability in the field. This 20-gauge inverted choke delivers a 35–65% shot pattern that suits hunting scenarios where you need a tighter spread than a modified choke alone—think tighter coverage for longer shots without the density of full choke. Made from 17-4 stainless steel with black oxide pockets, it's engineered to resist corrosion and handle hard use season after season.

If you're running a 20-gauge shotgun for upland, waterfowl, or small-game hunting, choke selection makes a real difference in your success rate. The Midas Modified profile sits in that sweet spot between open and tight, giving you range and pattern consistency without over-choking your load. Black Rain Ordnance's reputation for quality means you're getting a tube that'll hold up to repeated cycling and cleaning.

At 4.8 ounces, the BRO TUBE is light enough that you won't notice it in your gun, and the inverted design offers a different shot-column behavior than standard chokes—useful if you're tuning your shotgun's performance for a specific style of hunting or a favorite load.

Frequently Asked Questions

What shotgun will this choke tube fit?

The BRO TUBE is a 20-gauge choke tube. It will fit any shotgun with a standard 20-gauge choke tube threading. If you're unsure whether your gun has interchangeable chokes, check your manual or contact the gun's manufacturer.

What does "inverted" mean on a choke tube?

An inverted choke has a reversed internal profile compared to a standard choke. This affects how the shot column compresses and performs downrange, offering different ballistics than conventional chokes. Some shooters prefer inverted profiles for specific loads or hunting scenarios.

Is this choke suitable for hunting?

Yes. The 35–65% pattern of the Midas Modified profile is designed for hunting applications where you need moderate constriction—tighter than improved cylinder but less restrictive than full choke. It works well for upland game, waterfowl, and small-game hunting.

What's the difference between this and a standard modified choke?

The Midas Modified is a variant of the modified constriction, and the inverted design changes how the shot column behaves versus a traditional modified choke. The specific 35–65% pattern and inverted geometry make it suited to certain loads and hunting styles; your results will depend on your specific shotgun and ammunition.
