HEVI-Shot 85631 Waterfowl Invector-DS 12 Gauge Extended Range 17-4 Stainless Steel Choke Tube - Black

The HEVI-Shot 85631 Waterfowl Invector-DS choke tube is a 12 gauge extended range choke built specifically for serious waterfowl hunters who demand reliable shot placement on ducks and geese at distance. Machined from 17-4 stainless steel and finished in black, this tube threads into Browning Invector-DS shotguns and delivers the tight, consistent patterns you need when birds are working at the edge of your effective range.

HEVI-Shot engineered this choke to work in harmony with their premium waterfowl loads, which pack denser, harder pellets than traditional lead shot. That density means tighter clusters and deeper penetration—exactly what you're after when you're committed to clean, ethical harvests on public water or private land. The stainless steel construction resists corrosion from saltwater spray and wet conditions, so the tube stays reliable season after season.

If you're running a Browning with Invector-DS chokes and you're serious about waterfowl shooting, this extended range tube belongs in your gun bag. It's a straightforward upgrade that pairs proven HEVI-Shot ballistics with a choke geometry designed to maximize your effective distance without sacrificing reliability in the field.

Specifications

Frequently Asked Questions

What shotguns does the HEVI-Shot 85631 fit?

This choke tube is designed for Browning shotguns with the Invector-DS choke system. Check your owner's manual or the existing choke tube in your gun to confirm Invector-DS compatibility before ordering.

Can I use this choke with regular lead waterfowl loads?

While the tube is machined to work with standard 12 gauge ammunition, HEVI-Shot designed this choke specifically to optimize patterns with premium waterfowl shot loads. Check your ammunition manufacturer's recommendations for choke compatibility.

Why is stainless steel important for waterfowl hunting?

Waterfowl hunting often involves wet conditions, saltwater marshes, and extended exposure to moisture. The 17-4 stainless steel construction resists corrosion far better than blued or uncoated steel, keeping the choke tube reliable and extending its service life in harsh field conditions.

What does "extended range" mean for a waterfowl choke?

An extended range choke produces a tighter, more concentrated shot pattern downrange, allowing you to deliver effective shot placement on waterfowl at greater distances than you could achieve with a more open choke constriction.
