Browning 1132883 Midas Invector-DS 20Gauge Improved Cylinder Stainless Steel
The Browning Midas Invector-DS 20-gauge choke tube in Improved Cylinder is a stainless steel choke built for shooters who want tighter patterning without sacrificing versatility. If you run a Browning shotgun with Invector-DS threading, this tube gives you the density and consistency you need for upland birds, clays, and hunting situations where you're working moderate distances. Stainless construction means it'll handle the elements—salt spray, moisture, repeated cleaning—without rust or degradation, so it's a solid long-term addition to your choke collection.
The Improved Cylinder constriction sits in the middle of the shotgun choke spectrum: tighter than a Cylinder choke for better shot grouping, but more open than Modified, so you're not wasting pellets on a pattern that's too dense at closer ranges. That balance makes it practical for hunters and clay shooters who don't want to swap tubes between stations or hunting setups. The Midas finish is Browning's signature corrosion-resistant treatment, so durability and reliability are built in.
Drop it into any Browning shotgun fitted with the Invector-DS system—check your owner's manual to confirm your gun uses this threading—and you're good to go. Choke tubes are wear items, so having a quality backup or rotating set keeps your gun tuned for different game and conditions.

Frequently Asked Questions
Will this choke tube fit my Browning shotgun?
This tube is designed for Browning shotguns with Invector-DS threading. Check your shotgun's documentation or contact Browning to confirm your gun uses Invector-DS; if it does, this choke will fit. Older Browning models or different systems require different choke types.
What does Improved Cylinder constriction do?
Improved Cylinder produces a tighter shot pattern than a Cylinder choke, giving you better pellet grouping and effective range. It's less restrictive than Modified, making it practical for moderate-range hunting and clay shooting where you want pattern density without over-constriction.
Why is stainless steel important in a choke tube?
Stainless steel resists rust and corrosion from moisture, salt, and repeated cleaning cycles. It extends the tube's lifespan and maintains reliable fit and performance over years of use.
