Best Taurus TX22 Chassis & PDW Kits 2026

Buy the Peak Defense MTN2 at $99. It is the only kit in this group that arrives with a folding brace and names Gen 1, Gen 1 Competition, Gen 2, T.O.R.O., and Compact fitment, so it is both the cheapest complete package and the one least likely to leave you guessing about your frame. If you own a Compact and want the fitment stated as its own configuration rather than folded into an all-model claim, MacMounts Thor's Grip at $145 is the pick, and you add a rear interface yourself.

Spend up to the Nine Lives Defense 9X22 at $224.99 when you want the widest accessory surface: 1913 rails at the rear, top, and bottom plus M-LOK side panels, in MJF-printed PA-11 nylon with a vapor-fused, double-polished finish. Go to the FarrowTech FX22 when the rear interface is the decision, since FarrowTech configures the rear around a stock, a Steadybrace, a Tailhook, or a unit you already own, and the front around a magazine holder, a Picatinny section, or a 10-degree carbon grip.

On the low end, the Peak Defense Spectre at $30 is the cheapest way to find out whether you like shooting a TX22 out of a chassis at all, and it still includes an optic mount, a backplate, and a charging handle. Before you order, stand the pistol up in our firearm builder to see which optics, magazines, and suppressors your specific TX22 accepts, and use the parts catalog to check prices on the pieces you still need.

Fitment across this field is not interchangeable, and the makers are specific for a reason. Calloway Designs writes that its kit does not fit the compact versions of the TX22 and will fit the full size, T.O.R.O., and Competition models with a full-length grip. BSsquirts states that the Battle Chassis has only been confirmed to work with the full-size frame. MacMounts states that Thor's Grip is designed for both the full size and compact variants, and labels its two frame options Full size (TORO - Competition) and Compact. Peak Defense lists the MTN2 as fitting the TX22 Gen 1, Gen 1 Competition, Gen 2, T.O.R.O., and Compact.

Nine Lives Defense and the Peak Defense Spectre both state all-model compatibility, and FarrowTech lists the FX22 for the Taurus TX22 without breaking fitment out by generation. Treat those as the maker's claim rather than a variant-by-variant guarantee, and confirm your exact model with the shop before ordering if you run a Compact or a Gen 1. Ether-3D is the narrowest of the group and says so plainly: the kit is tested on the Gen 2 full-size TX22.

Two base packages ship with a brace by default: the Peak Defense MTN2, which includes a Daedalus push-button folding brace, and the Ether-3D carbon fiber kit, which includes a folding 1913 stabilizing adapter with a matching brace. The FarrowTech FX22 can also be ordered brace-inclusive, since a polymer Steadybrace, an aluminum Steadybrace, a Tailhook MOD1, or a Tailhook MOD1C are selectable rear options rather than the default configuration.

The FarrowTech FX22 sits in the middle. FarrowTech configures the rear around a stock, a Steadybrace, a Tailhook, or supplying your own, and the front around a magazine holder, a Picatinny section, or a 10-degree carbon grip, with all installation hardware included and no permanent modification to the pistol. That flexibility is why the configured price can reach $380, roughly the top of this field.

The rest are chassis only. The Nine Lives Defense 9X22 gives you a rear 1913 rail and nothing on it. Calloway Designs puts a rear Picatinny mount on its full size kit and states that it accepts JMAC and Strike Industries style braces. MacMounts Thor's Grip adds a rear Picatinny rail with a QD sling plate. The Peak Defense Spectre ships with the chassis, optic mount, backplate, and charging handle, and nothing at the rear. Price those shells with the brace added before you compare them to the MTN2.

Every chassis here is additively manufactured, and the material is the single biggest quality signal on the spec sheet. This is not the hobby PLA that people picture when they hear 3D-printed TX22 chassis or go looking for a TX22 chassis STL. The Peak Defense MTN2 uses a PETG-CF chassis with a nylon-CF backplate and charging handle. The Peak Defense Spectre offers PETG-CF or PPA-CF, and PPA-CF is the stronger of the two options. Ether-3D prints its Minimalist chassis in PETG carbon-fiber reinforced material.

BSsquirts goes heavier with PA612-CF plus black-oxide and brass hardware, which is part of why the Battle Chassis lands at 2 lb, the heaviest verified shell in this group. MacMounts prints Thor's Grip in Polymaker PETCF with brass threaded inserts. Nine Lives Defense is the outlier on process: the 9X22 is MJF-printed PA-11 nylon, vapor fused and double polished, which is why it looks and feels like an injection-molded part rather than a printed one.

MacMounts is the only maker in this group that puts a limit on polymer in writing, noting that some flex is normal and recommending metal when you need competition rigidity or hard optic retention. That is worth internalizing before you mount a magnified optic to a printed rail and expect it to hold a mechanical zero through transport. BSsquirts is also explicit that its removable printed optic mount needs filing or sanding to sit in true alignment, so plan on fitting work rather than a pure bolt-on if you buy that one.

Magazines are the cheapest part of this build and the first thing that limits it. A chassis turns the TX22 into a gun you shoot in long strings from a braced position, and 16 rounds disappears fast at that pace. Three magazines is a reasonable floor, six to eight is the number that keeps a range session moving without a reload table, and the spare-magazine features on these chassis assume you own more than the two that came in the box.

Two of these kits build magazine storage into the shell. The Peak Defense MTN2 includes a push-button TX22 magazine holder, and Calloway Designs integrates a spare-magazine holder alongside a flared magwell. Calloway also states that its kit works with factory magazines and TandemKross Wingman +5 extensions, which is the detail to check if you plan to run extended basepads inside a magwell.

Match the magazine to the frame, not just the caliber. Full-size TX22 magazines and TX22 Compact magazines are different parts, so a Compact owner buying a chassis should buy Compact magazines at the same time.

The reason people search for a TX22 chassis with MP7 in the same breath is silhouette. A chassis with a folding rear brace, a top rail, and a forward grip surface puts the TX22 in the same shape as a compact PDW, and .22 LR makes it the cheapest way to spend a day shooting that layout. The kits that get closest are the Peak Defense MTN2, with its folding brace and removable side rails, and the FarrowTech FX22 configured with a 10-degree carbon grip up front.

What you are buying is the ergonomics, not the ballistics. If you want the actual 4.6x30mm platform that shape is imitating, our coverage of the UO Arms NT7 MP7 clone tracks the domestic civilian version and what it costs, and the gap between that price and a TX22 plus a chassis is most of the reason this category exists.

A chassis is also not the first TX22 upgrade for most owners. An optic, a trigger, and magazines change how the gun shoots more than the shell around it does. Our Taurus TX22 upgrades guide covers that order of operations, and if the goal is trigger speed rather than silhouette, the best TX22 forced reset triggers are the cheaper path to a faster gun. Note that the MTN2 offers a rate-reducer-ready configuration, so pick the right one at checkout if you are running a forced reset part.

A brace and a stock are not the same purchase legally, and this field sells both. The 2023 ATF pistol brace rule was vacated by the Fifth Circuit and is not being enforced, so a TX22 wearing a brace, including the folding brace that comes with the Peak Defense MTN2 or the Ether-3D kit, is not a short-barreled rifle under federal law right now.

A shoulder stock is the configuration that changes the answer. Put a stock on a pistol with a barrel under 16 inches and you have made a short-barreled rifle, which requires an approved ATF Form 1 and NFA registration before you assemble it. The making tax is $0 under the OBBBA and a Form 1 make runs longer than a transfer but still processes in weeks on the modern eForm pipeline rather than the months the legacy paper system took, and the application, background check, and registration all still exist. FarrowTech lists a stock among its rear options for the FX22, so that is the one configuration in this guide where the question actually comes up.

Then check your state law, because several states restrict short-barreled rifles regardless of a federal registration. If you want to skip the question entirely, buy one of the brace-equipped kits or a chassis with a rear Picatinny rail and mount a brace to it.
