Overview
Built for hunters who want a dedicated waterfowl setup, this 20 gauge tube is designed to extend slightly beyond the barrel and deliver patterns suited to work out to about 40 yards. Its improved-cylinder-like paper pattern and patented stud ring are intended to shorten the shot string, while the knurled end allows hand tightening without tools. SecureFit threading is included for a tight fit, and the tube is made from heat-treated 17-4 stainless steel with a non-reflective bronze finish. It is not ported, so hunters looking for porting-related recoil or muzzle-jump reduction will need to consider that trade-off.

Considerations & Trade-offs
- Extends about 3/8" beyond the barrel, so it adds a small amount of visible length at the muzzle.
- Designed for an effective range out to 40 yards, so it is not intended as a long-range option.
- Patterns similar to improved cylinder constriction on paper, which may be a less open setup than some hunters expect for close-in work.
- It is not ported, so it does not include the recoil and muzzle-jump reduction associated with ported tubes.
