Carlson's Delta Waterfowl Extended Long-Range 20ga Browning Invector Plus

Carlson's Delta Waterfowl Extended Long-Range Choke Tube

When you need to stretch your effective range on waterfowl, this extended choke tube delivers the pattern density and consistency that separate successful hunts from frustrating misses.

Design & Construction

17-4 Stainless Steel Construction — Built to withstand the corrosive environment of waterfowl hunting and the unique demands of steel shot. The material resists pitting and degradation far better than conventional choke tubes.

Extended Parallel Section — The 25% longer parallel section is the key to this tube's performance. It compresses the shot column more gradually, resulting in:

• Denser, more uniform patterns
• Fewer flyers at extended ranges
• Better performance with larger steel shot sizes

Extended Design — Projects 3/4 inch beyond the barrel, protecting your shotgun's bore from erosion caused by repeated steel shot use.

Performance Recommendations

This long-range tube excels at 40+ yard shots and is optimized for steel shot. Do not use steel shot faster than 1550 FPS or shot sizes larger than BB through this choke tube. All steel shot sizes work well in the close and mid-range versions of this line.

Why Choose This Tube

Waterfowl hunters who regularly take extended shots understand that pattern consistency matters as much as pattern density. This choke tube delivers both, giving you the confidence to take ethical shots at distance while maintaining the reliability you need in the field.
