Black Rain Ordnance
The BRO TUBE 20GA Invector Midas Improved Modified choke tube is a premium upgrade for 20-gauge shotguns built around Invector-Plus specs. Black Rain Ordnance engineered these tubes as a drop-in replacement for flush-mount chokes, extending slightly beyond the barrel for intuitive handling in the field or at the range. They're built from 17-4 stainless steel with a durable black oxide finish and a distinctive laser-etched gold accent band—functional aesthetics that signal serious hardware. Whether you're fine-tuning patterns for upland hunting, sport shooting, or checking performance across different load combinations, this Improved Modified constriction bridges versatility and precision.
The design philosophy here is practical durability. The extended tube profile makes removal and swaps painless without tools, and the stainless construction stands up to repeated use and the elements. Black Rain Ordnance applied their Invector-Plus long-taper choke geometry to minimize plastic wad buildup in the bore—a real concern when you're shooting regularly. The high-resolution finish treatment supports that goal, keeping your barrel cleaner between cleaning sessions and letting you focus on patterning and hunting rather than maintenance surprises.
Improved Modified chokes deliver a 45–75% pattern density window, making them a solid middle ground: tight enough to maintain effective range on distant targets, open enough to give you margin on closer birds. That balance makes this tube a workhorse for hunters who don't want to constantly swap tubes or dial in different loads for every situation. If you're running factory Invector-Plus barrels and want to step up from OEM flush tubes, this is a straightforward, reliable upgrade.
| Brand | Black Rain Ordnance |
| Gauge | 20 |
| Choke Type | Invector-Plus |
| Choke Constriction | Improved Modified |
| Pattern Percentage | 45–75% |

This tube is designed for 20-gauge shotguns with Invector-Plus barrels only. If your barrel is marked Invector-Plus (not standard Invector or another system), this tube will drop in. Confirm your barrel marking before ordering.
The BRO TUBE extends slightly beyond the barrel, making it much easier to grip and remove by hand—no tools needed. Flush tubes sit flush with the muzzle but require more effort to access. If you're swapping tubes frequently or prefer faster field adjustments, the extended design is a practical upgrade.
Improved Modified throws a 45–75% pattern density, balancing range and spread. It's tighter than Modified or Full, giving you better reach on distant targets while still leaving room for closer shots without excessive pellet stringing.
Only the choke tube itself is included. No wrench, case, or accessories are provided—the tube installs directly into your Invector-Plus barrel.
