Mossberg 510 Youth Mini 20 GA Pump Shotgun - Black (Model 50485)$433.03
Availability: In Stock
The Mossberg 510 Mini .410 bore pump action shotgun is a compact, lightweight option built for shooters who need a manageable shotgun without sacrificing function. At just 5 pounds and 34.75 inches overall, this .410 is genuinely small enough for younger shooters, smaller-framed adults, and anyone who values a handy gun that doesn't tire you out in the field or at the range. The pump (slide) action is familiar and reliable—the same manual-of-arms that's made Mossberg shotguns trusted workhorses for generations.
The 18.5-inch vent-rib barrel keeps the gun nimble while the fixed-modified choke and dual-bead sight setup make it straightforward to point and shoot. The real standout feature is the adjustable length of pull: a spacer system lets you dial in either 10.5 or 11.5 inches, so you can grow into the gun or fit it precisely to your frame. That matters. A stock that doesn't fit is a stock that doesn't shoot well, and Mossberg got that right here.
The .410 bore is the smallest shotgun gauge in common use, which means lighter recoil and lower ammunition cost—ideal for learning the fundamentals or for small-game hunting and clay shooting where power isn't the priority. It's not a hard-hitting turkey or waterfowl gun, but it's honest about what it is. The synthetic stock and blued barrel are built to handle field use without fussing, and the 3-inch chamber gives you versatility in ammunition choice.
