Mossberg 505 Youth All Purpose .410 Bore 20" Shotgun - Model 57120

The Mossberg 505 Youth All Purpose .410 Bore shotgun is a trim, manageable firearm built for young shooters and hunters stepping up from air rifles or .22s. With a 20-inch barrel, 12-inch length of pull, and a measured 5.25 pounds, the 505 scales to smaller frames without sacrificing the genuine feel and handling of a real shotgun. The .410 bore delivers modest recoil and gentler shot string, making it an excellent introduction to clay shooting, upland hunting, or small-game pursuits—and it's light enough that a young hunter can carry it all day in the field.

Mossberg engineered the 505 with the same attention to reliability that backs their reputation. The fixed-modified choke keeps patterns tight for hunting applications, while the 20-inch vent-rib barrel and dual-bead sight system help young shooters develop sight picture and follow-through. The five-round capacity covers most hunting scenarios, and the 3-inch chamber opens options for both standard and magnum .410 loads. Blued barrel and wood furniture give it a classic shotgun look that encourages respect for the tool.

This isn't a toy gun or a training dummy—it's a scaled, purpose-built shotgun that grows with a shooter's skill. Whether your kid is learning proper gun handling at 4-H, tagging along on a dove hunt, or shooting clays on a Saturday morning, the 505 Youth delivers the manners, balance, and performance of a serious firearm in a package that actually fits.

Frequently Asked Questions

Is the Mossberg 505 Youth a good first shotgun for a young hunter?

Yes. The scaled 12-inch length of pull, light weight, and .410 bore with modest recoil are specifically chosen for developing shooters. The fixed-modified choke and ventilated rib support hunting and clay shooting, and the simple design teaches gun handling fundamentals without overwhelming.

What .410 ammunition does this shotgun use?

The Mossberg 505 has a 3-inch chamber, so it accepts both standard 2.5-inch and 3-inch .410 bore shells. You have flexibility to choose lighter recoil loads for practice or hunting-weight loads as the shooter develops.

Can adults shoot the Mossberg 505 Youth?

Absolutely. While the 12-inch length of pull makes it ideal for youth, adults with shorter arms or those who prefer a compact shotgun can shoot it effectively. The .410 bore and light weight also appeal to shooters who want less recoil for extended clay or hunting sessions.
