The Mossberg SA-20 is a dependable shotgun used for sporting clays and waterfowl hunting. It has proven capable of withstanding harsh conditions while still operating with very few issues, but for it to function properly it needs the right choke tube.
The Patternmaster Code Black and Carlson’s Cremator are two of the best choke tubes for the Mossberg SA-20. They can deliver results of over 80% of pellets inside a 30-inch circle at 40 yards with the right ammo. Carlson’s Long Beard XR is a great choke for turkey hunting that’s capable of providing dense patterns over 50 yards paired with Winchester XR ammo.

Chokes for the Mossberg SA-20 You Should Consider
These are the three chokes that you should consider for the Mossberg SA-20 shotgun that can produce more consistent and dense patterns downrange. The SA-20 is compatible with the Mobil choke tube system.
1) Patternmaster Code Black Choke Tube
The Patternmaster Code Black is a top-of-the-line choke tube that provides unmatched performance in long-range hunting situations. This choke tube uses a specialized constriction design that helps to control the spread of shot at longer distances. This makes it an ideal choice for waterfowl hunters who need to take shots at moving targets from a distance.
Patternmaster choke tubes work by using internal ring studs to halt the wad from the shot column just before it leaves the barrel, resulting in less disruption to pellet distribution that happens when separation occurs outside the barrel. The Code Black is capable of putting over 80% of pellets within a 30-inch circle at 40 yards with the right ammo. The Code Black choke works well with the SA-20 and is best for medium to long range shots of up to 60 yards. Expect it to pattern closer to a full choke. This is the TOP pick.

The Carlson’s Cremator choke tube is an excellent choice for hunters who need a versatile choke that can perform well with a variety of shotshell loads. This choke tube uses a unique design that consists of multiple tapers, which work together to provide a consistent shot pattern. This makes the Cremator ideal for hunting situations where you need to be able to adjust your shooting style quickly and accurately.
The Cremator line of chokes is a ported design that patterns well with the SA-20. This is a Mossberg extended choke tube set with a Mid Range .597” Diameter (Improved Modified) and Long Range .587” Diameter (Light Modified) choke. This choke set allows you to change chokes quickly for in close decoying or longer shots if the birds aren’t working well. This is the BUDGET pick.

With its versatility and reliable performance, the Carlson’s Long Beard XR Choke is an excellent choice for any serious turkey hunter.
The newer Mossberg SA-20 shotguns excel for hunting turkeys and the Long Beard choke by Carlson’s is a good fit.

Do extended choke tubes provide better patterns?
In the field, extended choke tubes can outperform stock choke tubes. It’s critical to consider things like ammo and choke constriction while using extended chokes.
Extended choke tubes provide several advantages, including the ability to remove the choke without a choke wrench since it extends past the barrel, the ability to see the choke size stamped on the side of the choke without removing it, and the fact that most aftermarket choke tubes are extended.
If you use factory choke tubes, you’re limited to the diameter of chokes that come with the shotgun. Three choke tubes are usually utilized, ranging in diameter from open to tight. When it comes to personalizing your choke and ammo, extended choke tubes provide you additional options.

Does it really matter if a choke tube is marked for ducks or geese?
No, it’s not true. Choke tubes are frequently branded for ducks or geese, but this is generally done only for marketing purposes. Some makers claim it’s made to make choosing a choke tube simple, and although that may be true for casual waterfowl hunters, a duck or goose label doesn’t convey the whole story.
All that matters is the choke tube’s diameter. For duck hunting, some choke tubes may have open chokes, whereas for goose hunting, they may have tighter chokes. It makes sense to label the choke by species in this circumstance. However, this is rarely the case, as most choke tubes are identical regardless of whether duck or goose is inscribed on them.
Always compare technical parameters and examine the choke diameter. Compare technical specifications of each choke tube rather than relying on a duck or goose designation.
Tips on Improving Your Mossberg SA-20 Patterns
- Test as many choke and ammo combinations as possible.
- Chokes and ammo specifically designed for each other tend to work the best. The technology and development put into the front end just can’t be ignored.
- Pattern your shotgun at the max distance you plan on shooting in the field.
- Limit your patterning to a 30-inch diameter circle for waterfowl or 10-inch for turkeys
- Compensate for shot drift in high winds or pellet fall at long distances.
- Switch to dense shot like TSS or Hevi-shot for increased pellet energy and density.
- Use an aftermarket sight for a better shot profile.
- Average your results from 3 shots before giving up on a particular load.
What to expect
When it comes to choosing the right choke tube for the Browning SA-20 shotgun, Patternmaster Code Black stands out from its competitors. The Patternmaster Code Black is engineered with a unique design that provides consistent and even shot patterns, resulting in better accuracy and a higher precision. Unlike most of its competitors, the Patternmaster is built with a wad halting design, which ensures that the wad and shot column separate cleanly, reducing the chances of having holes or gaps in your pattern. Additionally, the Code Black’s longer parallel section helps to reduce recoil, which in turn leads to more controlled shots and better follow ups. Overall, the Patternmaster Code Black is a top performer, delivering outstanding results that set it apart from the competition.
Bottom Line
The Mossberg SA-20 is a popular shotgun for waterfowl due to its dependable performance for many years. Easily recognizable with its slim profile, the SA-20 has proven its dependability and smooth operating for many hunters.
The best choke for the Mossberg SA-20 is the Patternmaster Code Black. It can deliver tight patterns out to 60 yards on waterfowl. Carlson’s Cremator is another good option, especially their choke tube sets which come with mid and long-range tubes.
Finally, the Long Beard XR choke delivers dense patterns with Winchester XR ammo out of the SA-20 for turkey hunting. Whichever choke you pick, make sure it fits Mossberg shotguns with the Mobil choke system.
