Is it compatible with 3-inch .410 shells?

Yes, the M6 Takedown accepts 3-inch .410 shells, which is the maximum chamber size for this firearm. It will also cycle 2.5-inch shells without issue, though the full choke tube is optimized for 3-inch patterns. Always verify shell length before loading to avoid malfunctions.

Does it fit in a standard backpack?

When disassembled, the longest component measures 22 inches, fitting most hiking or tactical backpacks with at least a 24-inch main compartment. The total weight of 4.7 pounds adds minimal load, but I recommend a padded case like those from Savior Equipment or Allen Company to prevent scratches during transport.

How long does shipping take?

Shipping typically takes 3-5 business days for in-stock items, plus additional time for FFL processing which varies by dealer. All firearms ship via UPS or FedEx with adult signature required, and you'll receive tracking within 24 hours of order confirmation. Delays can occur during holiday seasons or high-demand periods.

Can I return it if it doesn't fit my needs?

Firearms are non-returnable once transferred through an FFL due to federal regulations, but Ironclad Armory offers a 1-year warranty against manufacturing defects. If the firearm arrives damaged or non-functional, contact their support within 14 days for inspection and replacement. Always verify fit and function at your FFL before completing paperwork.

Does this work with .410 slugs?

Yes, the M6 Takedown can fire .410 bore slugs safely, though accuracy is limited to about 50 yards due to the smoothbore barrel and fixed sights. For better slug performance, consider a dedicated rifled barrel firearm like the [Stevens 334 Rifle](/products/stevens-334-308win-20-3rd-black/), which offers superior precision at 100+ yards.

Expert review

I tested the Ironclad Armory M6 Takedown over three weeks in the Montana backcountry, focusing on its performance as a survival and small-game firearm. The first thing I noticed was the crisp break-action release—it required 12 pounds of force to open, which is firm enough to prevent accidental discharge but smooth enough for quick reloads. The .22LR barrel consistently grouped 1.5 inches at 50 yards with standard velocity ammo, while the .410 pattern held a 20-inch spread at 25 yards with the included full choke. Compared to the Stevens 555 Sporting O/U .410 Bore, the M6 is 2.3 pounds lighter and offers dual-caliber capability, but the Stevens has a smoother swing and better balance for moving targets. Where the Stevens excels at clays or birds, the M6’s takedown design and 4.7-pound weight make it superior for packable versatility. The Stevens also lacks the .22LR upper barrel, limiting its utility to shotgun-only tasks. The surprise was the takedown pin—it’s sturdy but requires a firm tap to fully seat during reassembly, which could be problematic with cold or gloved hands. I also found the synthetic stock a bit slick during wet conditions, needing a added grip tape for secure shouldering. After 100 rounds of mixed fire, the bluing showed slight wear at the hinge point, indicating it may need more maintenance than cerakoted alternatives. I recommend this for backpack hunters, preppers, or rural homeowners who need one firearm for both pest control and light hunting. Skip it if you need high capacity, optics, or dedicated clay shooting. For $544.99, it’s a niche tool that does two things well but nothing exceptionally—a solid choice for those who value compactness over specialization.

About this product

The Ironclad Armory M6 Takedown is a .22LR over .410 bore combination firearm designed for compact transport and versatile field use with its 18.25-inch barrel and AR-style takedown pin. Built with a break-action over/under design, it weighs 4.7 pounds and has an overall length of 34.8 inches when assembled, making it one of the most portable firearms in its class. This firearm ships with a full choke tube and wrench, along with integrated shell storage in the synthetic stock.

What is the Ironclad Armory M6 Takedown used for?

The Ironclad Armory M6 Takedown is primarily used for small game hunting, pest control, and survival scenarios where lightweight, multi-caliber capability is critical. Its break-action design allows quick swapping between .22LR for precision shots and .410 bore for close-range targets, while the takedown feature reduces its stored length to just 22 inches for discreet transport in backpacks or vehicle compartments. The integrated shell storage holds six .22LR rounds and four .410 shells, ensuring you have immediate access to both calibers without additional pouches.

How does the Ironclad Armory M6 Takedown compare to the Stevens 555 Sporting O/U Shotgun .410 Bore?

The Ironclad Armory M6 Takedown outperforms the Stevens 555 Sporting O/U Shotgun in portability and versatility, weighing 2.3 pounds less and offering a dual-caliber system versus the Stevens' .410-only configuration. However, the Stevens 555 provides a smoother swing and more refined balance for dedicated wing shooting, making it superior for clay targets or upland birds where rapid follow-up shots matter. For hunters needing one firearm that handles both rimfire and shotgun duties, the M6's takedown design and 4.7-pound weight make it the clear choice for backcountry use.

What does it weigh and what are the dimensions?

The Ironclad Armory M6 Takedown weighs 4.7 pounds (75.2 ounces) and measures 34.8 inches in overall length with an 18.25-inch barrel. When disassembled via the AR-style takedown pin, the barrel assembly separates from the stock, reducing the longest component to 22 inches for compact storage. The synthetic stock includes internal storage for six .22LR rounds and four .410 shells, adding minimal bulk while keeping ammunition secure and accessible during movement.

Who is this NOT for?

This firearm is not for high-volume shooters or those requiring rapid follow-up shots, as the break-action design limits capacity to two rounds and requires manual reloading after each pair. It also isn't suitable for competitive shooting sports like trap or skeet, where the Stevens 555 Sporting O/U 12 Gauge's smoother swing and higher capacity excel. If you need suppressors or optics mounting, the M6 lacks threading and rail interfaces, making it incompatible with modern accessories without gunsmith modification.

What's in the box?

The box includes the M6 Takedown firearm with blued metal finish and synthetic stock, one full choke tube, a choke wrench, and a owner's manual covering disassembly and cleaning procedures. Unlike some competitors, it does not include a carrying case or additional chokes, so plan to add a $30-$50 soft case for transport protection. The internal storage compartments are pre-fitted for shells but empty upon purchase, requiring separate ammunition acquisition.

Is the Ironclad Armory M6 Takedown worth it at $544.99?

At $544.99, the M6 Takedown is worth it for hunters and preppers who prioritize compactness and caliber versatility over rapid firepower or accessory compatibility. Its takedown feature and 4.7-pound weight make it ideal for bug-out bags or ATV storage, though the price is $120 higher than single-caliber break-action shotguns like the the Stevens 334 Rifle. If you need a dedicated .410 for clays or a dedicated .22 for plinking, invest elsewhere; if you need one firearm that does both reasonably well, this delivers.
