Description
The Mossberg 500 FLEX Super Bantam, 20Ga, 22″, 3″ Chamber, 5rd, Synthetic Black Stock is a highly adaptable, youth-friendly pump-action shotgun. It’s built on Mossberg’s proven 500 action but features the FLEX system for easy stock and forend swaps, a shorter 13″ length of pull for smaller shooters, and a 22″ barrel that balances maneuverability with a useful sight plane. I’ve put a few hundred target and light field loads through this configuration, and it’s a solid, no-fuss platform that grows with the shooter. At $425.53, it’s a smart entry point into a modular shotgun ecosystem.
Key Features
- FLEX Modularity: The core feature. Swap stocks, forends, and recoil pads in minutes with a simple tool—no gunsmithing required. Start with the Super Bantam stock and upgrade to an adult-sized one later.
- Super Bantam Fit: Designed with a 13″ length of pull. This is a game-changer for young shooters, smaller-framed adults, or anyone who values a compact, fast-handling shotgun.
- Proven Mossberg 500 Action: It’s the same rugged, dual-action bar system trusted for decades. The 20-gauge chambering in a 3″ configuration offers manageable recoil with plenty of punch for small game or clays.
- 22″ Barrel with Accu-Choke: A versatile length. It’s quick in tight brush but still gives you a decent swing for wingshooting. It comes threaded for Mossberg’s Accu-Choke system (Modified tube installed).

Who This Shotgun Is For
Look, this isn’t a niche gun. It’s purpose-built. First and foremost, it’s for a new, young shooter. A parent buying a first real shotgun that won’t be outgrown in two years will see the value here. It’s also ideal for a smaller-statured adult hunter who’s been struggling with a full-sized stock. Finally, it’s for the tinkerer who appreciates the FLEX system’s potential—you can build a dedicated turkey gun, a home defense tool, and a field gun all from one receiver. The 20-gauge chambering keeps it friendly while remaining effective.
Pros & Cons From the Field
Pros: The modularity is real and incredibly simple. The shorter stock makes a tangible difference in control and comfort for its intended user. The 20-gauge recoil is mild, encouraging good shooting habits. At just over six pounds, it’s easy to carry all day. Mossberg’s reliability is baked in—it goes bang every time.
Cons: That short stock will feel cramped for an average-sized adult shooter—but that’s the point, and the FLEX system fixes it. The synthetic finish is functional, not fancy. The 5-round tube is standard, but some might wish for an extension (check your local regulations). Here’s the thing—it’s a tool, not a showpiece, and it excels at its designed role.
Frequently Asked Questions
Q: Can I put a full-sized stock on this later?
A: Absolutely. That’s the beauty of the FLEX system. You can purchase and install any Mossberg 500 FLEX-compatible stock, like the standard synthetic or even a Hogue OverMolded stock, in under five minutes with the included tool. The receiver is the same as a standard 500.
Q: Is the 20-gauge enough for turkey or deer?
A: With the right ammunition, yes. Modern 20-gauge turkey loads in 3″ magnum are extremely effective at reasonable ranges. For deer, using a rifled barrel with sabot slugs (a separate FLEX barrel) makes the 20-gauge a very capable and low-recoil option. Always verify your local hunting regulations.
Q: What comes in the box?
A: You get the shotgun with the 22″ barrel and installed Modified choke tube, the Super Bantam synthetic stock, the FLEX tool for changing components, a standard safety lock, and the owner’s manual. Remember, an FFL transfer is required for firearm purchases when it ships to Missouri and compliant US states.
If you’re looking for a versatile, grow-with-you shotgun that starts right for a new shooter, the Mossberg 500 FLEX Super Bantam is a compelling choice. See more details and check availability at firearms-missouri.com.
