Mossberg 510 Mini Super Bantam 20GA 18.5in Mossy Oak Camo

About this product

The Mossberg 510 Mini Super Bantam 20GA is a purpose-built youth pump-action shotgun featuring an 18.5-inch vent-rib barrel, an adjustable length-of-pull system ranging from 10.5 to 11.5 inches, and a Mossy Oak camo finish. This 5-pound shotgun is designed to provide a safe, manageable introduction to the platform for smaller-framed shooters while maintaining Mossberg's signature ambidextrous tang safety and dual-bead sight picture. At a listed weight of 5 lbs and an overall length of 34.75 inches, it fills a specific niche in the introductory firearms market.

What is the Mossberg 510 Mini Super Bantam used for?

The 510 Mini is primarily used as a training and introductory firearm for young or small-framed shooters in clay target sports and small-game hunting. Its adjustable stock system allows for a proper, safe fit as the shooter grows, while the included Accu-Set chokes (Full, Modified, Improved Cylinder) provide versatility for different target distances and shot types. The Mossy Oak Break-Up Country finish makes it suitable for field use, particularly in brushy or timbered environments.

How does the Mossberg 510 Mini compare to the Stevens 555 Sporting Compact?

The Mossberg 510 is a better choice for a dedicated training tool, while the Stevens 555 Sporting Compact 20ga is superior for competitive clay fundamentals. The 510's pump action and 5 lb weight force a shooter to master the manual of arms and manage recoil intentionally, whereas the 26-inch-barreled over-under Stevens 555 Compact offers a more intuitive swing and faster follow-up shots for sporting clays. For pure target breaking, the Stevens 555 Compact has the advantage, but the 510 builds foundational skills.

What does it weigh and what are the dimensions?

The shotgun weighs 5 lbs (approximately 2268 grams) unloaded and measures 34.75 inches in overall length with the 18.5-inch vent-rib barrel. The critical dimension is the length of pull, which adjusts from 10.5 inches to 11.5 inches using the included spacer system; this 1-inch adjustment range is the key to fitting a shooter over several years of growth. The 3-inch chamber accommodates standard 20-gauge shells up to 2.75 inches or magnum loads, offering flexibility for different applications.

Who is this NOT for?

This shotgun is not for an adult shooter seeking a primary hunting or defensive firearm, nor is it ideal for a shooter who has already outgrown the maximum 11.5-inch length of pull. Its compact dimensions and light weight become a liability for a full-sized adult, creating an awkward, cramped shooting position that can hinder proper form. Additionally, if your primary use is trap or skeet shooting with high round counts, a dedicated over-under like the Stevens 555 will offer better balance and faster target acquisition.

What's in the box?

You receive the complete shotgun, three Accu-Set choke tubes (Full, Modified, Improved Cylinder), the adjustable length-of-pull spacer kit, a standard choke tube wrench, and the owner's manual. The spacer kit includes the hardware to incrementally adjust the stock, a crucial component for adapting the firearm over time. Unlike some competitors, Mossberg does not typically include a hard case; plan for a third-party carrying solution for transport and storage.

Is the Mossberg 510 Mini worth it at $497.99?

At $497.99, the 510 Mini represents solid value as a dedicated youth training platform that can adapt over several years, avoiding the need for multiple firearm purchases. The cost is justified by the robust pump-action mechanism, adjustable stock system, and versatile choke set that together create a comprehensive learning tool. Compared to buying a full-sized shotgun and having a gunsmith permanently shorten the stock—a $150+ modification that can't be reversed—the 510's built-in adjustability is a cost-effective, long-term solution.
