The Mossberg 90017 is a no-nonsense 18.5" security barrel built for Mossberg 500 and Maverick 88 shotguns in 12 gauge. If you run a 6-shot model and need a shorter, purpose-built barrel for home defense or breaching work, this OEM replacement gives you a compact package without sacrificing reliability. The cylinder bore keeps shot patterns tight at defensive distances, and the simple bead sight is fast and instinctive when it matters most.
This is genuine Mossberg factory hardware—the same engineering and fit you'd expect from the manufacturer. The matte blued finish handles hard use without fussing over finishes, and the breacher-profile design keeps things straightforward. Swap it onto your existing receiver in minutes; if you already own a 500 or 88, you know how to do it.
Keep in mind: this barrel is spec'd for 6-shot models. The Mossberg 500 Cruiser and 500 Chainsaw use different receiver geometry, so they're not compatible here. Verify your platform before ordering.

Frequently Asked Questions
Will this barrel fit my Mossberg 500 Cruiser or 500 Chainsaw?
No. This barrel is not compatible with the Mossberg 500 Cruiser (#54125) or 500 Chainsaw (#50460) due to receiver differences. Verify that you own a standard Mossberg 500 or Maverick 88 6-shot model before ordering.
What is cylinder bore, and how does it affect my shot pattern?
Cylinder bore is the least restrictive choke constriction. It produces tight, consistent patterns at close defensive distances—ideal for home defense and tactical applications where you're engaging targets at short range.
Is this an OEM Mossberg part?
Yes. This is the genuine Mossberg 90017 factory barrel, manufactured to original specifications for direct fitment to compatible 500 and Maverick 88 receivers.
What comes in the box?
The barrel ships as a standalone component. You receive the barrel with bead sight already installed; no additional hardware is included.
