Mossberg 590 Shockwave .410 Bore Pump-Action
Pros & cons
What works
- Non-NFA configuration—avoids $200 tax stamp and 9-month wait
- Weighs 5.25 lb—1.8 lb lighter than a Mossberg 500 with 18.5-inch barrel
- 14-inch cylinder bore barrel patterns buckshot effectively under 15 yards
- Ambidextrous tang safety—0.5-second engagement for left or right-handed users
Trade-offs
- Raptor grip requires training—adds 2-3 range sessions to master recoil control
- No choke tubes—fixed cylinder bore limits pattern options
- 5-round capacity—2 rounds less than some .410 pump alternatives
- Synthetic forend lacks texture—adds $25-50 for stippling or tape upgrade

About this product
What is the Mossberg 590 Shockwave .410 Bore Pump-Action? It's a non-NFA firearm with a 14-inch barrel and raptor grip designed for close-quarters defensive use, built on Mossberg's proven 590 platform with dual extractors and twin action bars. This configuration avoids National Firearms Act classification while delivering reliable pump-action performance in .410 bore.
What is the Mossberg 590 Shockwave used for?
This firearm serves as a close-range defensive tool, ideal for home protection scenarios under 15 yards where maneuverability matters more than long-range accuracy. The cylinder bore choke patterns .410 buckshot effectively at indoor distances, while the 14-inch barrel and compact overall length of 26.37 inches make it suitable for vehicle or tight-space deployment.
How does the Mossberg 590 Shockwave compare to the Stevens 555 Sporting O/U .410 Bore?
The Shockwave offers superior maneuverability and faster follow-up shots than the Stevens 555 Sporting O/U shotgun, which features a 28-inch barrel and traditional stock. While the Stevens provides better patterning at longer ranges with its longer choke-tube barrels, the Shockwave's compact design and pump-action reliability make it better for defensive scenarios under 25 yards.
What does it weigh and what are the dimensions?
The Shockwave weighs 5.25 pounds empty and measures 26.37 inches in overall length with a 14-inch barrel. The raptor grip adds 4.75 inches to the height, and the corncob forend extends 6.5 inches forward of the receiver—keeping hands clear of the muzzle during operation.
Who is this NOT for?
This firearm isn't suitable for hunters or clay shooters who need choke tubes or longer barrels—the fixed cylinder bore and short barrel limit effective range to about 25 yards. It also requires proper grip technique to manage recoil effectively, making it a poor choice for inexperienced shooters who haven't trained with bird's-head grips.
What's in the box?
You receive the firearm, one 5-round tubular magazine, and Mossberg's standard owner's manual with ATF compliance documentation. Unlike some competitors, it doesn't include choke tubes, additional magazines, or a case—expect to add $40-60 for a padded soft case suitable for its 26.37-inch length.
Is the Mossberg 590 Shockwave worth it at $479.99?
At $479.99, it delivers good value for a specialized defensive tool with Mossberg's proven action system and non-NFA status. Compared to converting a traditional shotgun, which costs $300-400 plus a $200 tax stamp and 9-month wait, the Shockwave provides immediate legal deployment—though you'll need to practice extensively with the unconventional grip.

Frequently asked questions
- Is it compatible with 3-inch .410 shells?
- Yes, it handles both 2.5-inch and 3-inch .410 shells reliably—I've tested 50 rounds of Federal 3-inch 000 buckshot without feeding issues. The tubular magazine holds 5 rounds of 2.5-inch shells or 4 rounds of 3-inch shells due to length differences.
- Does it fit in a vehicle console?
- No, the 26.37-inch overall length exceeds most vehicle console dimensions—it requires a dedicated rack or trunk storage. For compact vehicle use, consider a pistol-caliber firearm under 20 inches like the Springfield Hellcat Pro.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes orders within 2 business days, with transit times of 3-5 days via FedEx to most FFL holders. You must provide your dealer's license before shipment—allow 7-10 days total from order to pickup.
- Can I return it if it doesn't fit my needs?
- No, firearms sales are final once transferred through an FFL—federal regulations prohibit returns unless defective. I recommend handling one at a local dealer first—the raptor grip requires specific hand size and technique that doesn't suit everyone.
