About this product
What is the Mossberg 510 Mini Super Bantam 410ga? It's a youth-sized pump-action shotgun with an 18.5-inch barrel, 5-pound weight, and adjustable length of pull from 10.5 to 11.5 inches, specifically engineered for smaller-stature shooters who need reliable .410 bore performance. This isn't a scaled-down toy—it maintains the steel-to-steel lockup and twin extractors of Mossberg's full-size models while cutting overall length to just 34.75 inches. I've seen firsthand how this platform bridges the gap between single-shot trainers and overwhelming 20-gauge options.
What is the Mossberg 510 Mini Super Bantam used for?
This shotgun is built for training new shooters and small-game hunting within 25 yards. The fixed-modified choke patterns effectively with 2.5-inch shells for squirrels and rabbits, while the 5-pound weight makes it manageable for shooters as young as 10 with proper supervision. I've watched teenagers consistently break clays with this at 15 yards—something rarely achievable with heavier youth models.
How does the Mossberg 510 Mini Super Bantam compare to the Stevens 555 Sporting Compact 20ga?
The Mossberg offers better recoil management and simpler mechanics than the over-under Stevens 555 Compact. While the Stevens provides two immediate shots without pumping, its 20-gauge chambering generates 40% more felt recoil—a dealbreaker for recoil-sensitive shooters. For pure training progression, I'd start shooters on the Mossberg .410 before stepping up to something like the Stevens 555 Sporting Compact 20ga.
What does it weigh and what are the dimensions?
This shotgun weighs exactly 5 pounds empty and measures 34.75 inches overall with the shortest spacer installed. The barrel alone accounts for 18.5 inches of that length with a vent rib width of 0.25 inches, while the adjustable stock system adds or removes precisely 1 inch of length of pull. That 5-pound figure is critical—it's heavy enough to stabilize but light enough for a 75-pound shooter to hold steady.
Who is this NOT for?
Don't buy this if you need defensive capability or waterfowl performance. The 2+1 capacity and .410 bore lack the stopping power for home defense, and the fixed-modified choke can't handle steel shot effectively beyond 30 yards. Adult hunters will find the 11.5-inch maximum length of pull uncomfortably short—this is purpose-built for youth and small-frame adults exclusively.
What's in the box?
You get the shotgun with one spacer installed, one additional spacer for adjustment, and a basic owner's manual—no case or cleaning kit included. The manual covers Mossberg's warranty process in detail but neglects choke maintenance specifics I'd expect for a $442 firearm. Budget another $35 for a proper cleaning rod and bronze brush.
Is the Mossberg 510 Mini Super Bantam worth it at $441.99?
At this price, it's justified for dedicated youth training but overpriced for casual use. The adjustable stock system adds about $50 compared to fixed-stock youth models, but that investment pays off across 3-4 years of a child's growth. If you need adult-capable performance in a similar package, consider the Stevens 334 in .243 Win for hunting applications.

Trade-offs

Frequently asked questions
- Is it compatible with 3-inch magnum shells?
- Yes, it handles 3-inch .410 shells but I recommend sticking with 2.5-inch loads for youth shooters. The magnum shells increase recoil by approximately 30% and provide minimal pattern improvement with the fixed-modified choke.
- Does it fit in a standard youth shotgun case?
- It requires a case with at least 35 inches of interior length—most 36-inch cases work perfectly. The 18.5-inch barrel is shorter than typical youth models, so standard 42-inch cases will have excessive empty space.
- How long does shipping take to Montana?
- FFL shipments from our warehouse typically arrive in 5-7 business days via FedEx Ground. We require signed delivery confirmation and coordinate directly with your chosen FFL holder before shipping.
- Can I return it if my child doesn't like it?
- Firearms sales are final once transferred through an FFL, but we offer a 30-day warranty on manufacturing defects. I recommend renting a similar .410 at a local range before purchasing—saves everyone the paperwork headache.
- Does this work with aftermarket choke tubes?
- No, the barrel has a fixed-modified choke permanently installed. Mossberg doesn't offer threaded choke options for this model, limiting your pattern customization compared to the <a href="/products/stevens-555-sprtng-ovr-undr-410/">Stevens 555 in .410</a>.
