Description
Picture this: you’re in a Missouri hardwood bottom, the first light just hitting the frost. A whitetail is moving at 80 yards through the timber. You need a shot that’s precise, fast, and reliable from a cold, damp stand. That’s the exact scenario the Benelli M2 Field 20 Ga Shotgun, 24″ Rifled Slug Barrel, 3″, Black Synthetic is built to dominate. It’s a purpose-built slug gun designed for hunters who demand rifle-like accuracy from a smoothbore platform, offering the legendary inertia-driven speed of Benelli in a dedicated deer and boar hunting configuration.
Here’s the thing—this isn’t a field gun you’re adapting. It’s a dedicated system. The 24-inch rifled barrel is cold hammer-forged for consistent, long-term accuracy with modern sabot slugs. The inertia-driven action, proven in military and competition use, cycles everything from light target loads to stout 3-inch magnum slugs without adjustment. It’s a system that fits out of the box, requiring no gunsmithing to be hunt-ready. At 6.4 pounds, it carries like a dream all day but stays steady for that crucial off-hand shot.
Key Features
The heart of this setup is the 24-inch rifled slug barrel. This isn’t a smoothbore with screw-in chokes; it’s a true 1:28 twist rifled bore engineered to stabilize high-performance saboted slugs from brands like Federal Premium and Hornady. That means you’re not guessing where your round will hit—you’re building a consistent, sub-MOA capable dope card for your chosen ammunition. The black synthetic stock is weatherproof and tough, with Benelli’s classic ergonomics and a textured grip that holds secure with wet hands or gloves.
Benelli’s inertia system is the star. It uses the recoil energy of the fired shell to cycle the action, not gas. Look, that means less fouling, more reliable operation in dirty conditions, and a cleaner-running firearm. The rotating bolt head locks securely into the barrel extension, the same robust design used in the M4. The trigger is crisp, and the safety is a large, positive cross-bolt design right in front of the trigger guard. The receiver is drilled and tapped for scope mounts, compatible with popular one-piece bases from brands like EGW (Evolution Gun Works) for a solid optic platform.

Pros & Cons

Who It’s For
This is for the serious deer hunter in shotgun-only zones, or anyone who wants a fast-handling, close-to-mid-range woods gun with more authority than a carbine. It’s for the hunter who values a lightning-fast second shot on driven game or follow-ups on feral hogs. It’s also an ideal choice for a younger or smaller-framed shooter who needs a manageable-recoiling, yet highly effective, big-game tool. This model is available at firearms-missouri.com for Missouri residents and nationwide.
Frequently Asked Questions
Q: Can I shoot birdshot or buckshot through this rifled barrel?
A: No. You should only shoot sabot slugs through a rifled barrel. Shooting shot or foster-type slugs will damage the rifling and lead to poor accuracy and potential safety issues. This barrel is a dedicated slug system.
Q: What kind of accuracy can I expect?
A: With quality, matched sabot slugs, sub-2-inch groups at 100 yards are a reasonable expectation from a rest. Many users report consistent 1.5-inch groups, making it effective well beyond typical shotgun ranges.
Q: Does it come with choke tubes?
A: No. This model features a fixed, permanently attached rifled barrel. It does not use or accept choke tubes. Its sole purpose is to deliver maximum accuracy with sabot slugs.
