KELTEC KS7 GEN2 12ga 18.5in Green 6+1 Pump Shotgun
About this product
What is the KELTEC KS7 GEN2 12ga 18.5in Green 6+1 Pump Shotgun? It's a compact bullpup pump-action 12-gauge whose 26.1-inch overall length redefines maneuverability without moving into NFA-regulated Short-Barreled Shotgun territory. This is a purpose-built tool for close-quarters defense and tactical applications, not a field gun, and its design choices reflect that singular focus. If you've handled a traditional Mossberg 590 or Remington 870, the KS7's footprint will feel like a different category entirely.
What is the KELTEC KS7 GEN2 used for?
The KS7 GEN2 is designed for confined-space defensive use where a traditional shotgun's length is a liability. It's a primary choice for vehicle defense, trail carry as a formidable wildlife deterrent, and home defense in tight floorplans where its 26.1-inch length allows you to corner a hallway without telegraphing your position. The cylinder bore choke pattern provides consistent spread at defensive distances, but this isn't the platform for clay shooting—that's a job better suited to our Stevens 555 Sporting O/U.
How does the KELTEC KS7 GEN2 compare to the Mossberg 590 Shockwave?
The KS7 is a more concealable and controllable system than a Shockwave-style firearm for most shooters. While both maintain non-NFA overall lengths, the KS7’s 26.1-inch length is 4.5 inches shorter than a standard 590 Shockwave, and its bullpup configuration moves the action and center of mass rearward, making one-handed manipulation during reloads or transitions more balanced. The Mossberg’s Raptor bird’s head grip offers a more compact profile but sacrifices control under rapid 12-gauge recoil; the KS7's conventional shoulder stock provides superior recoil management and sight picture acquisition, especially with its integrated fiber optic front post.
What does it weigh and what are the dimensions?
The KS7 GEN2 weighs 5.9 pounds unloaded, with an overall length of 26.1 inches and a height of 7.5 inches. Its 18.5-inch barrel is the minimum legal length for a non-NFA shotgun, and the magazine tube accepts six 3-inch shells or seven 2.75-inch shells for a 7+1 capacity. To put that in perspective, it’s nearly 10 inches shorter than a standard Remington 870 with an 18.5-inch barrel, and its weight distribution over the shooter's shoulder makes it feel lighter during extended carry.
Who is this NOT for?
This shotgun is not for the shooter who needs a versatile field gun, a competition platform, or a first firearm. The bullpup pump action has a distinct mechanical feel, with a slightly longer and stiffer forend travel of about 8 inches compared to a traditional pump. If your primary use involves hunting waterfowl, busting clays, or shooting 3-Gun stages that require frequent reloads from a belt, a conventional shotgun like our Stevens 555 Sporting Compact will be a better, more familiar fit.
What's in the box?
You receive the KS7 GEN2 shotgun, one flush-fit 3-inch 00-buck shell ready for function testing, the removable Picatinny rail cap for the forend, an operator’s manual, and a polymer bore flag. KELTEC does not include a hard case or cleaning kit, so budget an additional $40-$60 for a quality 28-inch soft case and a basic 12-gauge cleaning rod. The manual includes explicit warnings about 18.5-inch barrel length compliance—read it before you transport the firearm anywhere.
Is the KELTEC KS7 GEN2 worth it at $631.99?
Yes, at $631.99 it represents strong value for its specific defensive niche, offering a unique capability set that traditional shotguns can't match at that price point. You're paying for the R&D behind a reliable bullpup pump design and the material savings of its monolithic polymer receiver, not for premium wood or adjustable chokes. Compared to converting a standard shotgun to a similar compact form, which often involves a $200+ stock kit and permanent modifications, the KS7 is a turn-key solution that retains its factory warranty and avoids any regulatory gray area.

Pros & cons
What works
- 26.1-inch overall length — nearly 10 inches shorter than a standard 18.5" barrel pump shotgun
- Weighs 5.9 pounds unloaded — 1.2 pounds lighter than a Mossberg 590A1 with comparable barrel length
- 7+1 capacity with 2.75" shells — one more round than many standard tube-fed defense shotguns
Trade-offs
- Bullpup pump action has an 8-inch forend travel — longer and stiffer than traditional pumps, requires deliberate training
- No adjustable choke system — cylinder bore only limits range versatility for birdshot or slugs beyond 40 yards
- Synthetic forend rail is molded-in — cannot be removed or replaced without significant gunsmithing

Frequently asked questions
- Is it compatible with Remington 870 or Mossberg 500 accessories?
- No, the KS7 GEN2 uses a proprietary mounting system and its bullpup design prevents cross-compatibility with most standard shotgun accessories. The molded Picatinny rail on the forend accepts any MIL-STD-1913 accessory, but you'll need to source KELTEC-specific parts like spare magazine tube followers or aftermarket charging handles from vendors like M*CARBO or Hi-Tech Custom.
- Does it fit in a standard rifle case?
- Yes. The KS7's 26.1-inch overall length allows it to fit inside a standard 28-inch rifle or shotgun case with room to spare. For reference, the internal compartment needs to be at least 27 inches long to accommodate the firearm without compression on the muzzle or buttpad.
- How long does shipping to an FFL take?
- For in-stock items, Ironclad Armory processes and ships within 2 business days once your FFL's license is verified and payment clears. Transit time varies by carrier and location, but most shipments arrive at the receiving FFL within 5-7 business days from the ship date.
- Can I return it if there's a mechanical issue?
- Ironclad Armory accepts returns for firearms with verifiable mechanical defects within 30 days of your FFL's transfer. The firearm must be unfired and in original condition for a full refund; if it has been fired, it will be directed to KELTEC's factory warranty service, which typically has a 4-6 week turnaround for repairs.
