Description
Named after the legendary Key of Solomon, the Mafteah (Hebrew for "key") is IWI's answer to the compact 12 gauge question, and it brings some clever engineering to the table. Instead of a gas system, it runs a recoil-operated action with the recoil spring wrapped around the magazine tube, a proven layout that goes back to some of the most reliable autoloaders ever made. That design choice is what lets IWI keep the whole package so short while still cycling shells the way a semi-auto should.
What Makes the Mafteah Different
The 14-inch smooth bore barrel wears a vent rib up top and a fixed cylinder choke, so it patterns well with defensive loads at close range. The 3-inch chamber gives you flexibility on ammo, with the tube holding 5 rounds of 2 3/4-inch shells or 4 rounds of 3-inch. The receiver comes drilled and tapped for MOS optics or a 1913 rail section, so adding a red dot is a simple job. Up front, M-LOK slots on the handguard handle lights and other accessories, and the reinforced polymer birdshead grip includes QD attachment points for a sling.
Handling and Controls on the IWI Mafteah
IWI put real thought into the controls here. The charging handle is enlarged, knurled, and reversible for lefties or righties, the bolt release is oversized and easy to hit under stress, and the crossbolt safety sits right behind the trigger where your finger naturally finds it, even with gloves on. At around 5.75 pounds, this thing points fast and swings easy in hallways and vehicles where a full-size shotgun feels like a canoe paddle.
Why Pick the Mafteah 12 Gauge
Compact scatterguns in this category are usually pump guns. Getting semi-auto speed in a footprint this small, from a company with IWI's reputation for building rugged, duty-grade firearms, is what sets the Mafteah apart. If you want maximum 12 gauge capability in minimum space, this is a strong way to get there.

Frequently Asked Questions
How does the IWI Mafteah cycle reliably with such a short barrel?
The Mafteah uses a recoil-operated action with the recoil spring wrapped around the magazine tube, a layout famously proven on classic autoloaders like the Browning Auto-5. Since it doesn't rely on a gas system that needs barrel length to work, the design stays dependable even in this compact format. It's a big part of why the whole package can be so short without giving up semi-auto function.
Can I mount a red dot on the Mafteah?
Yes. The receiver comes drilled and tapped and ships with a MOS optics plate, so you can mount a compatible red dot directly or add a 1913 rail section for other optics. The vent rib barrel still gives you a solid sighting reference if you prefer to run it without glass.
What shells does the IWI Mafteah 12 gauge run?
It has a 3-inch chamber, so it handles both 2 3/4-inch and 3-inch 12 gauge shells. The tube holds 5 rounds of 2 3/4-inch or 4 rounds of 3-inch, plus one in the chamber. As with most recoil-operated guns, it tends to run best with full-power loads rather than very light target ammo.
Is the Mafteah left-hand friendly?
More than most. The enlarged, knurled charging handle is reversible so it can be swapped to either side, and the crossbolt safety behind the trigger is easy to work from either hand, even with gloves. The oversized bolt release is also simple to reach regardless of which shoulder you shoot from.
