Quick take: PTR has introduced The Jack SBS FS, a compact pump-action shotgun built around a 7.25-inch 12-gauge barrel. Because that barrel sits well under 18 inches, the gun is a short-barreled shotgun regulated under the National Firearms Act, so it transfers on an ATF Form 4 rather than over the counter. At $1,100 MSRP it slots in as a purpose-built, close-quarters pump for buyers willing to do the NFA paperwork.
- What it is: A short-barreled, pump-action 12-gauge shotgun sold as an NFA item on a Form 4.
- Key detail: Hogue OverMolded Rubber ‘Tamer’ furniture and an AR-style forward pistol grip aim to make the stubby 12-gauge easier to control.
- Specs: 12-gauge, 7.25-inch barrel, 2+1 capacity, ships with both a full buttstock and a rear pistol grip plus a removable six-round side saddle; no sights included.
- Who it’s for: NFA collectors and home-defense buyers who want a maneuverable pump and don’t mind the transfer process.
What PTR built
The Jack SBS FS is a pump-action 12-gauge trimmed down to a 7.25-inch barrel. That short tube is the whole point of the design: it makes the gun far more compact than a standard 18- or 20-inch pump, which is useful in tight spaces but also puts it squarely into short-barreled shotgun territory. Capacity is listed at 2+1, meaning two shells in the tube and one in the chamber.
PTR clearly designed the gun around handling a hard-recoiling round in a small package. The furniture is Hogue’s OverMolded Rubber ‘Tamer’ line, which the name suggests is meant to soak up some of the punishing recoil that comes with a lightweight 12-gauge. A removable six-round side saddle rides on the receiver to keep spare shells on the gun, and it ships without sights, leaving the mounting choice to the buyer.
Furniture and controls
The Jack ships configurable, with two rear-end options in the box. Buyers get both a full buttstock and a rear pistol grip, so the same gun can be set up as a shoulder-fired pump or run as a more compact grip-only configuration where legal. That flexibility matters on a short-barreled shotgun, where overall length and how you shoulder or brace the gun are part of the appeal.
Up front, PTR fitted an AR-style forward pistol grip to the pump. That gives the support hand a vertical grip to drive the action and hang on to a gun that generates a lot of muzzle energy for its size. Combined with the Tamer furniture, the layout is built to keep a stubby 12-gauge under control rather than letting it buck around.
Why it’s an NFA item
A shotgun with a barrel under 18 inches is a short-barreled shotgun, and that classification is what triggers the NFA rules. The National Firearms Act regulates SBSs the same broad way it regulates suppressors and other restricted items, so The Jack transfers on an ATF Form 4 rather than a standard over-the-counter sale. In practice that means a registered transfer, a background check, the applicable NFA transfer process and a wait, plus a federal transfer tax on top of the purchase.
State law is the other gate. Short-barreled shotguns are legal to own federally through the NFA process, but some states restrict or ban them outright, so eligibility depends on where you live. If you’re not sure where your state lands, our US Gun Laws by State: 2026 Directory is a useful starting point before you start a Form 4.
Price and where it fits
PTR lists The Jack SBS FS at $1,100 MSRP. That’s the sticker on the firearm itself, before you factor in the federal transfer tax and any dealer or trust costs that come with an NFA purchase. For a buyer already comfortable with the paperwork, it’s a straightforward, purpose-built pump rather than a converted sporting gun.
The NFA landscape has been busy lately, with ongoing legal fights over how the government regulates these items. A recent example is covered in our report on how Texas Fails With Federal Suppressor Challenge, which shows the framework governing SBSs and suppressors alike is holding firm for now. Anyone eyeing The Jack should plan around that existing process rather than expecting it to change.
