Mossberg OEM 500 20-Gauge 24" Rifled Slug Barrel with Cantilever Scope Mount and Rifle Sights - Model 90060

The Mossberg OEM 500 20-gauge rifled slug barrel is a dedicated replacement or secondary barrel that transforms your Mossberg 500 shotgun into a precision slug shooter. Built by Mossberg for their own platform, this 24-inch barrel pairs a rifled bore with a cantilever scope mount and integrated rifle sights—giving you the optics and aiming tools serious slug hunters need without aftermarket modifications or guesswork about compatibility.

A rifled slug barrel is the way to go if you're serious about accuracy past 50 yards. The rifling imparts spin to saboted slugs, tightening groups dramatically compared to smoothbore patterns. Whether you're hunting deer in thick timber, setting up an ambush in a box stand, or working closer-range hunting situations where a slug gun outshines a rifle, this barrel gives you legitimate 100-plus-yard capability with the right ammunition and optic. The cantilever mount is already there—just add a scope matched to your shooting distance and hunting style.

Mossberg 500 owners know the platform's strength: quick, reliable, affordable, and endlessly configurable. This OEM barrel honors that ethos. It's made to spec for Mossberg 500 receivers, so fit and function are guaranteed. The blued finish and rifle sights are classic, rugged, and proven. If you've got a 500 on the shelf and you're thinking about a dedicated slug gun setup, this barrel beats buying a whole new gun—swap it in, mount glass, and hunt.

Frequently Asked Questions

Will this barrel fit my Mossberg 500?

Yes. This is an OEM Mossberg barrel designed for Mossberg 500 receivers. It will also fit Maverick 88 models with 6-shot capacity, as noted by the manufacturer. If you own either platform, this barrel drops on without modification or special tools.

Can I use this barrel for hunting?

Absolutely. The rifled bore is purpose-built for slug hunting. The 24-inch length offers good handling in brush and thick timber while the rifling significantly improves accuracy with modern saboted slugs at hunting distances. The cantilever scope mount and rifle sights give you two aiming options depending on your setup and preference.

Do I need a specific type of slug ammunition?

The rifled barrel is designed to shoot saboted slugs, which use a plastic sabot to grip the rifling and spin the projectile. Do not use rifled slugs (Foster-type) in a rifled barrel; use saboted ammunition for best accuracy and safety. Always follow ammunition manufacturer guidance and test your load for reliability and accuracy before hunting.

What optics can I mount on the cantilever?

The cantilever mount accommodates standard Picatinny rail accessories. Scope rings and optics rated for Picatinny mounts will fit. Your choice depends on your hunting style and distance—shotgun scopes, red dots, and lower-power rifle scopes are all viable options depending on your preferred slug hunting range.
