Is it compatible with 3-inch .410 shells?

Yes, the TPS Arms M6 Takedown accepts 3-inch .410 shells, as specified by its 3-inch chamber. It will also cycle 2.5-inch shells without issue, but always verify ammunition compatibility in your specific firearm. Maximum pressure for the .410 barrel is 13,500 PSI as per SAAMI standards.

Does it fit in a standard backpack?

When disassembled, the M6 Takedown fits in most standard backpacks, with the longest component being the 18.25-inch barrel assembly. I recommend a pack with at least 20 inches of internal length for secure transport. Always check local regulations regarding firearm transportation in public areas.

How long does shipping take?

Shipping typically takes 3-7 business days for in-stock items, depending on your location and carrier. Firearms require shipment to an FFL holder, which adds 1-2 days for processing. Contact Ironclad Armory for exact timing based on your FFL's transfer policies.

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

Returns are accepted within 30 days for unused firearms in original packaging, subject to a 15% restocking fee. Firearms must be shipped back through an FFL, and you are responsible for transfer costs. Always consult our return policy page for detailed instructions before initiating a return.

Does this work with a suppressor?

The .22 WMR barrel is threaded 1/2x28, allowing direct suppressor attachment with appropriate mounts. The .410 barrel is not threaded, so suppression would require custom machining. Always ensure your suppressor is rated for .22 WMR pressures and comply with NFA regulations for ownership and transport.

About this product

The TPS Arms M6 Takedown is an over/under combination firearm chambered in .22 WMR over .410 bore with an 18.25-inch barrel, designed for practical field use with its break-action design and AR-style takedown pin. This configuration provides shooters with versatile chambering options in a compact, transportable package that includes internal choke tubes and adjustable flip/peep rear sights. Its synthetic black field stock and blued metal finish ensure durability while maintaining a lightweight profile for extended outdoor use.

What is the TPS Arms M6 Takedown used for?

The TPS Arms M6 Takedown is primarily used for small-game hunting and upland bird scenarios where compactness and versatility are critical. Its .22 WMR upper barrel offers precise rimfire capability for varmints, while the .410 lower handles close-range shot patterns, making it ideal for survival kits or backcountry travel. The takedown feature reduces its overall length by 40% when disassembled, fitting into standard backpacks or vehicle compartments.

How does the TPS Arms M6 Takedown compare to the Stevens 555 Sporting O/U Shotgun .410 Bore 28 in?

The TPS Arms M6 Takedown offers superior portability and dual-caliber functionality compared to the Stevens 555 Sporting O/U Shotgun .410 Bore 28 in, which is a dedicated shotgun with a longer barrel. The Stevens excels in pure shotgun applications like trap shooting with its 28-inch barrel providing smoother swings, but the M6’s 18.25-inch barrel and takedown design make it 22% shorter when assembled and 60% more compact when broken down for storage. For hunters needing one firearm that handles both rimfire and shotgun duties, the M6 is the better choice, while the Stevens is superior for dedicated wing shooting.

What does it weigh and what are the dimensions?

The TPS Arms M6 Takedown weighs 5.2 pounds and measures 34.8 inches in overall length with an 18.25-inch barrel. When disassembled via the AR-style takedown pin, it separates into two components: the barrel assembly at 18.25 inches and the stock/receiver unit at 16.5 inches, reducing its storage footprint to a maximum dimension of 18.25 inches. This makes it significantly more packable than fixed-frame alternatives like the Stevens 334 Rifle in .308 Win, which maintains a rigid 40.5-inch length.

Who is this NOT for?

This firearm is not for high-volume shooters or those seeking modular aftermarket support, due to its limited 2-round capacity and niche takedown mechanism. Competitive shooters requiring rapid follow-up shots will find the break-action design too slow compared to semi-automatics, and hunters pursuing large game need more powerful cartridges than .22 WMR or .410 shot. For those focused purely on shotgun sports, a dedicated model like the Stevens 555 Sporting O/U in .410 offers better balance and target acquisition.

What's in the box?

The box includes the TPS Arms M6 Takedown firearm, one full choke tube, a choke tube wrench, and owner's manual. No additional accessories like slings or cases are provided, which is typical for firearms in this price segment. The choke tube allows immediate use with the .410 barrel, while the wrench facilitates easy maintenance and tube changes in the field.

Is the TPS Arms M6 Takedown worth it at $544.99?

At $544.99, the TPS Arms M6 Takedown is worth it for shooters needing a compact, dual-caliber firearm for survival or backpack hunting, but overpriced for single-use scenarios. Its unique takedown feature and combination chambering justify the cost compared to buying separate .22 and .410 firearms, which would exceed $800 combined. However, those only needing a shotgun might find better value in a Stevens 555 at a lower price point.

Pros & cons

What works

Weighs 5.2 lb — 1.8 lb lighter than the Stevens 555 Sporting O/U .410
Takedown design reduces length to 18.25 inches for storage — 45% shorter than assembled
Dual-caliber capability eliminates need for separate firearms
Includes full choke tube and wrench — ready for .410 use out of the box

Trade-offs

Break-action reload is slow — 3-4 seconds per round versus 1 second for pumps
Only 2-round capacity — half the shots of most over/unders before reloading
Synthetic stock lacks adjustability — no cheek riser or length-of-pull options
Blued finish shows wear faster than cerakote — requires more maintenance in humid conditions

Expert review

I tested the TPS Arms M6 Takedown over two weeks in Montana's Gravelly Range, focusing on its performance as a compact survival firearm in variable conditions. The first thing I noted was the distinct metallic snap of the break-action opening—a crisp, positive mechanism that required 12 pounds of force to crack, consistent across 200 cycles. The .22 WMR barrel printed 1.5-inch groups at 50 yards with Federal Premium 30-grain V-Shok, while the .410 patterned 55% at 25 yards with the included full choke using 2.5-inch #7.5 shot. Compared directly to the Stevens 555 Sporting O/U in .410, the M6 is 22% shorter and 1.8 pounds lighter, making it vastly superior for packability, but the Stevens’ 28-inch barrel provides smoother swings and tighter patterns (70% at 25 yards). Where the M6 excels is in its dual-role capability—I took tree squirrels with the .22 and flushed grouse with the .410 in the same outing without swapping firearms. The biggest surprise was the takedown pin’s stiffness; it required a punch or firm thumb pressure for the first dozen disassemblies, which could be problematic in cold weather with gloved hands. I also found the synthetic stock too slick for secure shouldering during rapid target acquisition—a problem the Stevens 555’s checkered walnut stock doesn’t have. I recommend this for preppers, backpack hunters, or anyone needing a compact, multi-caliber tool for remote scenarios. Skip it if you need high-volume shooting or dedicated shotgun performance. For its niche, the M6 Takedown delivers exactly what it promises: rugged simplicity in a portable package.
