Overview
Built for 20 gauge waterfowl setups, this choke tube is intended for hunters who want a dedicated decoy-range option in the blind. It fits Browning Invector Plus and Winchester SX3 platforms, with a bronze finish and a knurled end for hand tightening. The design extends slightly beyond the barrel and is described as offering an effective range out to 40 yards, with a pattern similar to improved cylinder constriction and a shorter shot string. It is not ported, so the focus stays on a simple, purpose-driven setup for close to mid-range duck hunting.

Considerations & Trade-offs
- Extends about 3/8" beyond the barrel, so it may be more noticeable than a flush-fit tube.
- Designed for an effective range out to 40 yards, so it is aimed at a specific hunting distance rather than all-purpose use.
- Patterns similar to improved cylinder constriction on paper, which may not match every shooter’s preferred spread.
- Not ported; the knurled end is for hand tightening, so installation and handling are straightforward but not tool-assisted.
