The Mossberg 510 Youth Mini is a 20-gauge pump shotgun built specifically for young hunters, shooters, and small-statured adults who need a gun that actually fits. Unlike scaled-down versions of adult shotguns, the 510 Mini is engineered from the ground up as a true compact platform—everything is proportioned smaller, from the receiver to the controls to the overall handling, making it genuinely comfortable and safe for smaller hands and frames. At just 5 pounds and 34.75 inches long, this is a shotgun designed to teach proper technique and build confidence without the fatigue and recoil struggle that comes from oversized guns.
The 18.5-inch vent-rib barrel features dual-bead sights for instinctive aiming, and the gun handles 2.75-inch shells with a 3-inch chamber and 4-round capacity. The real stand-out feature is the adjustable synthetic stock with spacer system: length of pull adjusts from 10.5 to 11.5 inches, so the gun genuinely grows with your kid rather than becoming obsolete after a season or two. That fit matters—it keeps the shotgun shouldered properly, improves accuracy, and reduces flinch-inducing recoil. The Accu-Set choke system gives you flexibility to match your load to the hunt or clay course.
This is a pump action, so it offers the reliability, simplicity, and hands-on learning curve that serious young shooters appreciate. Whether you're introducing a first-time hunter to upland birds, ducks, or target shooting, the 510 Mini delivers all the performance and durability Mossberg's known for in a package that doesn't overwhelm. The black synthetic furniture stands up to weather and hunting use without apology.

The 510 Mini handles 2.75-inch shells and has a 3-inch chamber, so it also safely fires 3-inch ammo. It's a straightforward choice if you're stocking standard 20-gauge loads for upland, waterfowl, or target shooting.
Yes. The adjustable synthetic stock includes a spacer system that lets you set length of pull anywhere from 10.5 to 11.5 inches. That means one shotgun can serve a young shooter for years without becoming too short as they grow, making it a genuine long-term investment in their shooting.
The product information provided covers the gun itself and its components. For a complete picture of what ships in the box, contact Bosque Outdoors directly.
The 510 Mini is a fully functional 20-gauge shotgun, so it's absolutely capable for hunting upland game, waterfowl, and small game where a 20 gauge is legal. Its short, lightweight profile also makes it a natural choice for young hunters who need a gun that doesn't exhaust them after hours in the field.
