Description

I was chasing a late-season tom through some nasty Missouri cedar thickets, my old pump gun feeling like an anchor. That’s when I started looking for a lighter, faster-handling turkey gun that wouldn’t break the bank. The Stoeger M3020 20 Ga, 24″ Barrel, 3″, Ghost Ring Sights, MO Obsession, 4rd kept coming up. Here’s what I found after putting a few boxes of heavy TSS through it.

The Stoeger M3020 is a gas-operated, inertia-driven semi-automatic 20-gauge shotgun chambered for 3″ shells. It features a 24″ barrel, ghost ring rear and fiber optic front sights, comes in MO Obsession camo, and has a 4+1 capacity. It’s a lightweight, reliable hunting shotgun designed for fast handling in the field. At $515.02, it’s a solid value for a dedicated turkey or upland gun.

Look, the big selling point here is the weight—or lack thereof. This thing comes in right around 6 pounds, which makes a huge difference when you’re carrying it all day or snapping it up to a sudden target. The 24″ barrel is the sweet spot for a 20-gauge in my opinion; it keeps the overall length manageable for tight cover but still provides a smooth swing. The MO Obsession camo isn’t just for show—it’s a great pattern for our early spring woods here in the Midwest.

The ghost ring sight system is what makes this a serious turkey contender. That big, open rear aperture lets you get on target incredibly fast, and the bright green fiber optic front just pops in low light. I’ve found it’s far more precise than a simple bead for those 40-yard shots. The action is Stoeger’s inertia-driven system, which is essentially a simplified, proven design. It cycled everything from light 7/8-oz target loads to punishing 3″ magnum turkey loads without a hiccup—no gunsmithing required to get it running right out of the box.

Here’s the thing—it’s not a fancy Italian over-under. The finish is utilitarian and the stock is synthetic, but that’s part of the package. You’re getting a no-nonsense tool that’s built to be carried through brush, leaned against a tree, and used hard. The 4+1 capacity is perfect for hunting regulations and keeps the profile trim. The gun shoulders naturally, and the length of pull works for a wide range of shooters. It’s a simple, effective platform that does one job very well.

Gauge: 20 Gauge (3″ Chamber)
Barrel Length: 24 Inches
Overall Length: Approx. 45 Inches
Weight: Approx. 6 lbs
Capacity: 4+1 Rounds
Sights: Ghost Ring Rear, Fiber Optic Front

Pros: Extremely lightweight and pointable. The ghost ring sight system is a major advantage for precise shot placement. Reliable inertia-driven action that handles a wide range of loads. The MO Obsession camo is effective and durable. Excellent value for a dedicated hunting semi-auto.

Cons: The synthetic stock and forend feel a bit basic. The trigger is serviceable but not exceptional. As with any inertia gun, you need to shoulder it firmly for reliable cycling—no lazy shooting. It’s a specialist, not a do-everything shotgun.

So who is this gun for? It’s for the hunter who wants a dedicated, lightweight turkey gun without spending a grand. It’s for the upland hunter chasing grouse in thick timber who needs a fast-handling 20-gauge. It’s also a great option for a younger or smaller-framed shooter who finds a 12-gauge too punishing. If your primary need is a simple, rugged, and effective hunting tool that ships to Missouri and compliant US states, this Stoeger deserves a hard look.

Frequently Asked Questions

Q: Will it cycle light target loads for practice?

A: Yes, reliably. The inertia system is known for being versatile. I’ve run everything from cheap 7/8-oz loads up to heavy 3″ magnums through mine without adjusting anything. Just remember to shoulder it firmly with the lighter stuff.

Q: Is the camo pattern just on the stock or the metal too?

A: It’s a full-dip camo that covers the entire receiver and barrel, not just the polymer parts. This gives you complete visual breakup and adds a layer of corrosion protection to all metal surfaces.

Q: Can I add a choke tube system to it?

A: It comes with Stoeger’s MobileChoke system, which uses the same tubes as many Benelli and Franchi shotguns. This gives you a huge range of aftermarket choke options from brands like Carlson’s, Trulock, and Jeb’s to tailor your pattern.

If you’re after a no-fuss, hard-working 20-gauge that’s built for the woods and fields, the Stoeger M3020 in this configuration is a compelling choice. See the full details and availability at firearms-missouri.com.
