The BRO TUBE 20GA Invector Plus Cylinder Choke Tube from Black Rain Ordnance is a replacement choke built for 20-gauge shotguns equipped with Invector-Plus threading. If you're running a back-bored barrel and want the flexibility to dial in your shot pattern, a cylinder choke delivers the most open constriction available—minimal pellet deformation and the widest spread downrange. This is your go-to for close to medium-range hunting or when you need maximum versatility in a single tube.
Built from highly polished 17-4 stainless steel, the BRO TUBE resists corrosion and wear through seasons of use. The flush-fit design sits cleanly with the barrel muzzle, no protrusion, which means a cleaner sight picture and easier gun handling in the field. Black Rain Ordnance holds these tubes to industry constriction standards, so you know what you're getting—consistent, predictable patterns shot to shot.
Whether you're patterning a new gun, working up loads for a specific game bird, or just prefer the open-choke philosophy for close-range work, the Invector-Plus platform has become standard on many modern 20-gauge shotguns. Keep a few tubes in your vest and adapt to conditions without swapping barrels.

The BRO TUBE 20GA Invector Plus Cylinder Choke Tube is designed for 20-gauge shotguns with Invector-Plus threading, typically found on back-bored barrels. Confirm your barrel has Invector-Plus compatibility before ordering.
Cylinder is the most open choke constriction available. It produces the widest, fastest-spreading shot pattern and is ideal for close to medium-range hunting where you need maximum coverage and minimal pellet deformation. Cylinder chokes are popular for brush hunting and early-season upland work.
Yes. A flush-fit choke sits level with the barrel muzzle, so it doesn't protrude beyond the end of the gun. This gives you a cleaner sight picture, easier gun handling in the field, and reduces snags on brush or gear.
17-4 stainless steel resists corrosion from moisture and powder residue, holds a fine polish, and is tough enough to handle repeated removal and installation without degrading the choke or the barrel threads.
