Introduction

Think American gun laws are strict? Think again. While some countries ban air rifles and kitchen knives, the US is home to a catalog of strange, quirky, and downright insane firearms you can legally own without a tax stamp or special paperwork.

From folding pistols to military hardware, here are 11 weird guns you can actually buy — and yes, they’re totally legal in most states.

1. Ohio Ordnance Works M2-SLR

• Caliber: 50 BMG

This is basically the M2 Browning Heavy Machine Gun that was mounted on armored cars in World War II and helicopter gunships in Vietnam. This was a pure weapon of war, and now Ohio Ordnance has made a semi-automatic, belt-fed version that is street legal.

Nobody needs a street-legal Ma Deuce, but then want and need are two very different things. And both military history buffs and fans of absolute chaos will love this 50 BMG icon that you can own at home. If you’ve got about 18K to spend.

2. Lifecard 22LR

• Caliber: 22LR

This one looks like a stack of metal credit cards, but folds out into a single-shot .22 pistol. It’s not a joke. It’s not a movie prop. It’s a real firearm, and you can buy it. Ideal for deep concealment, curiosity collectors, or confusing your friends at the range.

3. FN PS90

• Caliber: 5.8x27mm

The FN PS90 looks like a sci-fi prop, but it’s a real firearm you can legally own in the U.S. This civilian version of the military P90 features a futuristic bullpup design, top-mounted 50-round magazine, and fires the 5.7x28mm cartridge—a round originally designed to pierce body armor. Its compact shape makes it ideal for close-quarters combat, which is why elite law enforcement and military units around the world rely on its full-auto cousin. While the PS90 is semi-auto only, it still delivers high-capacity firepower in a radically ergonomic package that turns heads at the range and baffles traditional gun lovers.

It might look insane, like a Dali-esque vision of a gun that melted in the sun. Even so, it has the respect of military, law enforcement and private security teams around the world. Multiple special forces teams use these guns in urban combat, and if it’s good enough for them…

4. Bond Arms Cyclops 45-70

• Caliber: 45-70 Government

Yes, you read that right. A single-shot derringer that chambers the .45-70 Government — a round originally designed for rifles. The recoil is as savage as it sounds, it’s a total wrist breaker, but this little monster is 100% legal and totally unforgettable.

5. Standard Manufacturing DB-12

• Caliber: 12 Gauge

This double-barrel pump action shotgun is an answer to a question, nobody asked. It’s heavy, it’s unwieldy, inaccurate and it just makes no sense. But it’s all sorts of fun. You pump once, fire twice. Why? I mean I don’t even know, there’s almost no technical advantage here. It’s just different, and sometimes that’s enough.

6. Chiappa Rhino 30DS

• Caliber: 357 Magnum

A revolver that fires from the bottom cylinder instead of the top. It looks like an alien weapon and recoils like a kitten. Chambered in .357 Magnum, the Rhino is all about balance and innovation. There’s a reason for almost everything, but man it looks freaky.

You can get a full range of Chiappa revolvers, with much longer barrels and a choice of calibers, here.

7. Mare’s Leg Lever-Action Pistol

• Caiber: 357 Magnum, 44 Magnum

A chopped-down lever-action rifle that throws you straight into an old-school western. Usually chambered in .44 Mag or .357, this is one of those guns that makes no practical sense but every visual one. No stock, all style.

Woody Harrelson rocked one in the Zombieland movies and there’s just something infinitely cool about these.

8. Heizer DoubleTap Pistol

• Price:
• Caliber: 9mm/45 ACP

Ultra-thin, double-barrel, two-shot pistol chambered in 9mm or .45 ACP. It’s brutal, simple, and fits in a back pocket. Made for backup use, but it wins style points for minimalism.

9. IWI Tavor TS-12

• Caliber: 12 Gauge

It’s a bullpup shotgun with three rotating magazines and up to 15 shells. Or 25 mini shells. The IWI Tavor is ridiculously complicated, and it’s hard to justify it as a defensive shotgun, but it does put a smile on the face of just about everybody that picks it up.

10. North American Arms Mini Revolver

• Price:
• Caliber: 22LR

This tiny .22 revolver can literally be concealed in a belt buckle. We’re not joking. It’s so small you’ll question its legitimacy, but it’s a fully functional single-action revolver with a wild cult following. Not tactical, not practical — just pure American novelty.
