The Browning Invector-Plus 20 Gauge Full Flush Choke Tube in 17-4 stainless steel is a premium constriction tube designed for shooters who demand reliability and clean, professional fit. Built from highly polished 17-4 stainless steel, this full-choke option delivers durability and corrosion resistance whether you're hunting waterfowl, upland game, or running clay courses. The flush design sits seamlessly with your barrel's muzzle—no protrusion, no snag hazards, and a refined appearance that respects your shotgun's lines.
Invector-Plus tubes are engineered for Browning's back-bored barrel designs, using a longer choke taper that produces tighter, more uniform shot patterns. The full constriction level makes this tube ideal for longer-range work where pattern density matters—think 40+ yard shots over decoys or distant targets on the skeet field. Like all Browning choke tubes, it's manufactured to industry constriction standards, so you know exactly what you're getting in terms of pattern performance and compatibility.
If you shoot a Browning shotgun with Invector-Plus threading, a full-constriction tube deserves a spot in your rotation. The stainless-steel construction handles repeated use, field conditions, and the occasional neglect without pitting or rust. Swap it in when the situation calls for maximum density, swap it out when you need to open up the pattern—that's the beauty of a modular choke system.
| Gauge | 20 |
| Choke Type | Invector-Plus |
| Constriction | Full |
| Material | 17-4 Stainless Steel |
| Fit Style | Flush |
This is an Invector-Plus tube, so it will fit any Browning shotgun with Invector-Plus threading. If your gun uses the older Invector (non-Plus) system, this tube will not be compatible. Check your barrel or owner's manual to confirm which system your shotgun uses.
Full choke provides the tightest constriction in the Invector-Plus lineup, delivering the densest, most concentrated shot pattern. This makes it best suited for long-range shooting where keeping pellets grouped tightly downrange is critical. Looser constrictions like improved cylinder or modified are better for closer work where you want shot spread.
No. The flush fit simply means the tube doesn't stick out beyond the barrel muzzle—it's a cleaner look and eliminates snag hazards. The choke taper and constriction inside the tube remain unchanged, so you get the same full-choke performance and pattern density as a non-flush tube.
17-4 stainless is chosen for its strength, corrosion resistance, and ability to be highly polished. It stands up to repeated use, field moisture, and the occasional neglect without rusting or pitting—important when a choke tube is getting swapped in and out regularly or left in a gun used in wet conditions.
