Mossberg 92056 12 Gauge 24" Slug Barrel with Cantilever Mount, Fully-Rifled Bore & Blued Finish for Mossberg 500 & Maverick 88 6-Shot Models

The Mossberg 92056 is a 12 gauge slug barrel purpose-built for precision hunting and tactical shooting on Mossberg 500 and Maverick 88 shotguns. If you already own one of these 6-shot models and want to convert it from bird shot to dedicated slug duty without buying another gun, this fully-rifled barrel delivers the accuracy and sight picture you need. The 24-inch length strikes a practical balance between velocity, handling, and sight radius—compact enough for brush and truck work, long enough for slug distances where they count.

The fully-rifled bore is the key here. Unlike smooth-bore barrels, rifling imparts spin to a rifled slug or sabot round, tightening groups and extending effective range. That matters whether you're after deer in thick cover or running drills on steel. The integral cantilever scope mount comes ready to accept standard tactical or hunting optics, so you're not fumbling with additional rails or adapters. Blued finish resists rust and blends with the rest of your Mossberg's aesthetics.

Installation is straightforward: this barrel swaps onto your existing Mossberg 500 or Maverick 88 receiver with no modifications or gunsmithing. Keep your smooth-bore barrel for turkey and upland birds, and deploy this one when the mission is slugs. It's practical redundancy that costs far less than a second shotgun.

Frequently Asked Questions

Will this barrel fit my Mossberg 500 or Maverick 88?

Yes—this barrel is designed as a direct fit for Mossberg 500 and Maverick 88 shotguns with 6-shot capacity. No modifications to the receiver are required; it swaps on just like any factory barrel.

What's the difference between a rifled and smooth-bore slug barrel?

A rifled bore imparts spin to rifled slugs and sabot rounds, delivering tighter accuracy and better long-range performance. If you're serious about slug hunting or distance shooting, a fully-rifled barrel is the upgrade. Smooth-bore barrels work for buckshot and slugs at moderate ranges.

Do I need to buy a separate scope or mount?

The barrel includes an integral cantilever mount, so you just need to add your own optic. Any scope designed for shotgun cantilever mounts will attach directly—no additional rail or adapter required.

Can I use this barrel for ammunition other than slugs?

Rifled barrels are optimized for rifled slugs and sabot rounds. Buckshot and bird shot will function, but performance and patterning are best with rifled ammunition. Consult your shotgun manual for guidance on ammunition use.
