IWI Tavor TS12 Shotgun Review
IWI Tavor TS12 is a shotgun that breaks the mold and is one of the most innovative designs on the market. You can tell it’s a bullpup from some alien futuristic sci-fi movie, but it’s not just a pretty face. With a capacity of 15+1, rotating magazine tubes, and the compact handling design of a bullpup, this shotgun is nothing to mess around with.
The TS12 was designed for versatility—to be a home defense monster, a practical and fun range toy, or a manually operated tactical tool for professionals. In this review, I will go over the Tavor TS12’s design, performance, pros and cons, and if it is truly one of today’s unique shotguns.
IWI Tavor TS12 Bullpup: History
The TS12 was announced at the SHOT Show in Las Vegas in 2018 as a radically new idea for a 12 gauge bullpup semi-automatic shotgun with an unlimited capacity, an individual modular feeding system for each shell magazine. Its design was possible due to IWI’s strong bullpup rifle pedigree, primarily the Tavor TAR-21 and its variants, cannibalized by the IDF and other militaries across the globe.
IWI used its bullpup know-how to build a shotgun that was compact, easy to maneuver, and ergonomically sound designed to suit sport shooters, home defense, and tactical applications.
Key Design Concept
Instead of traditional tube-fed shotguns, the TS12 features a rotating magazine tube system (3 total tubes, each providing, 5 shells of 2¾” or 4 shells of 3″). By manually rotating the tubes, the user can cycle through 15 + 1 rounds, which was innovative for a bullpup shotgun at the time of its release.
A major part of the influence in creating the TS12 was the need for:
- High capacity without increasing barrel/tube length
- A Compact form factor with sufficient space for maneuvering in close quarters
- Bullpup ergonomics (rearwards action for balance and reducing overall length)
The TS12 is once again known as one of the most distinct semi-automatic tactical shotguns available. It clearly separates itself from competitors like the KelTec KSG or standard tube-fed semi-autos with a uniquely Israeli military-inspired design, high capacity, and compact bullpup build.
It is indicative of the move by IWI to diversify into shotguns from their normal line of rifles and SMGs, allowing civilian firearm owners the ability to own a tactical, high capacity shotgun based on Israel’s long tradition of utilitarian, rugged firearms.

IWI Tavor TS12 Bullpup: First Impressions
The first time you see the IWI Tavor TS12, it doesn’t look like a shotgun at all; it looks like something out of a sci-fi action movie. The angular lines, the chunky rear-end and the oversized controls give it a futuristic look, almost ominous. If you put it on a table next to a Mossberg or Remington pump, you’d think that they were from two different generations of firearm design.
Weight & Balance
When I lift it up, the weight at 8-pounds is noticeable, but it’s not front-heavy and this is common with other traditional shotguns. The total mass, given the bullpup design, is located much closer to your shoulder.
This causes the gun to feel short and compact, approaching carbine feel, yet it is concealing a full 18.5-inch barrel in that stubby framework. It seems like something designed for maneuvering in hallways, inside vehicles, or in tightly confined corners.
Ergonomics
Carrying the TS12 for the first time, the ergonomics do feel different, but they don’t feel awkward. The pistol grip fits comfortably into your hand, the trigger is at just the right distance, and the cheek weld feels natural. There is a mental change involved compared to the traditional form of shotguns.
Everything is closer to your body—the ejection, the chamber, and especially the rotating magazine tubes. It isn’t confusing, but it will take you a moment to re-orient yourself.
Magazine System
The star of the show—the revolving triple-tube magazine—doesn’t take long to get your interest. The concept of packing 15+1 shells of 2¾” into a semi-auto shotgun without the bulk of a drum or strange extension tube is inherently impressive.
The act of rotating between the tubes feels easier than expected—although initially strange, like trying something new at the gym: you know how it’s supposed to operate, but your hands lack the rhythm.
You can’t help but feel that this system is both your good fortune (monstrous capacity) and a burden (you’ll need hours of practice).
Sight & Controls
The TS12 has a full-length Picatinny rail, and it almost feels incomplete without some kind of red dot on top. There are barely noticeable iron sights, so I expect everyone is going to want to drop some kind of optic on there.
The oversized safety selector, charging handle, and bolt release were also very tactile. They are all meant for someone wearing a glove or dealing with high stress. They are chunky, tactile, and easy to find without actually looking. My first impression: this is a shotgun to run, not a shotgun to babysit.
IWI Tavor TS12 Bullpup: Performance
The TS12 is definitely a consistent shotgun, when you provide it with good ammo. It will cycle buckshot and slugs smoothly, and lighter birdshot will likely need some tuning or a break in period. The gas system works well in that it is consistent and keeps the action consistent under rapid fire.
There is stout recoil, but that is to be expected with a 12-gauge. However, the bullpup design holds the weight towards the rear, which helps with muzzle rise. Follow-up shots are significantly faster and easier than many traditional semi-autos.
The biggest performance advantage of the TS12 is its rotating triple-tube magazine system. With access to 15+1 rounds, you will be spending much less time reloading.
While it does take practice rotating tubes seamlessly under stress, having the option for tactical flexibility of staging different kinds of shells in each tube compared to a traditional magazine fed shotgun is priceless.
In the accuracy department, the shotgun patterns on point at defensive distances or will deliver solid slug performance out to 50 yards with use of the right optic and 7.5 CWD or 6 CWD slugs.
Overall, the TS12 delivers as a powerful, flexible, compact semi-auto shotgun that will be rewarding as you spend time learning a new and different system.
IWI Tavor TS12 Bullpup: Reliability
The IWI Tavor TS12 is considered to generally be a reliable semi-automatic shotgun when users choose appropriate ammo. When full power, buckshot and slugs are used, the shotgun cycles very clean and consistent, and holds the same rugged reliability we expect from IWI’s rifles.
Where some users run into issues is with light target loads, or cheap birdshot; these can and do, short stroke the action until the gun is broken in/slight gas port adjustment.
The rotating magazine tube design is innovative, but adds some complexity. It works as designed, but must be manipulated correctly; failure to rotate to the next magazine tube can cause feeding malfunctions.
In real world use, shooters who are vigilant with keeping the gun as clean as possible, use quality ammo, and practices rotating the tube, find it to be very reliable. It is not a “set and forget” type of gun as with pumps, but as long as you understand the quirks of TS12, it is a very reliable and fun shotgun for practical shooting and home defense.
IWI Tavor TS12 Bullpup: Pros & Cons
| Pros | Cons |
|---|---|
| Reliable with buckshot/slugs | Inconsistent with light birdshot |
| Adjustable gas system | Requires break-in period |
| Durable IWI build | Needs more cleaning |
| Tube system functions well | Misfeeds if tube not rotated fully |
Final Verdict: Good or Bad?
IWI Tavor TS12 is certainly a great shotgun, but in a very different way. It isn’t a simple pump gun that you can grab to load and forget. It is a really innovative bullpup semi-auto shotgun with a circulating magazine system that provides more capacity and versatility than any shotgun out there.
With good ammunition, maintained and not fouled, and practice on the manual of arms, the TS12 is reliable, capable, and very accurate for home defense or having fun at the range or tactical type applications.
The TS12 does have a lot of features that require more of a shooter, but if you can get past a learning curve of tube rotation, it is fussy with some lighter loads, and it does require more cleaning than traditional designs, the rewards are well worth the effort.
Verdict: The TS12 is a winner—an innovative, versatile, and reliable shotgun that challenges design norms.
