TPS Arms M6 Takedown O/U .410 18.25in Blued
About this product
The TPS Arms M6 Takedown O/U .410 18.25in Blued is an American-made, compact takedown shotgun designed for shooters who prioritize transportability and regulatory compliance. With its 18.25-inch barrel and AR-style takedown pin system, this firearm bridges the gap between traditional over/under shotguns and modern portable platforms. I evaluate it from the perspective of someone who's spent years navigating NFA regulations and field testing firearms in demanding conditions.
What is the TPS Arms M6 Takedown O/U .410 used for?
This shotgun serves best as a compact hunting and training tool, particularly for upland game and suppressor-friendly applications. The 18.25-inch barrel keeps the overall length at 34.8 inches when assembled, making it suitable for tight blinds or vehicle transport. With 3-inch chamber compatibility and included full choke tube, it handles everything from light target loads to heavier game loads effectively.
How does the TPS Arms M6 Takedown compare to the Stevens 555 Sporting O/U .410 Bore 28 in?
The M6 Takedown excels in portability while the Stevens 555 Sporting offers superior long-range patterning. The Stevens 555's 28-inch barrel provides better swing dynamics for clay shooting but requires 46 inches of storage space versus the M6's 18-inch broken-down length. For hunters needing to pack a shotgun into ATV storage or across rough terrain, the M6's 4.7-pound weight and takedown capability make it the clear practical choice.
What does it weigh and what are the dimensions?
This shotgun weighs 4.7 pounds with an assembled length of 34.8 inches and breaks down into two components measuring approximately 18 inches each. The 18.25-inch barrel contributes significantly to the compact profile, while the synthetic stock adds durability without excessive weight. When disassembled, the entire package fits into a 20-inch hard case with room for accessories.
Who is this NOT for?
Serious competitive shooters and waterfowl hunters should look elsewhere due to the limited capacity and shorter barrel. The 2-round capacity eliminates it from most clay competitions, while the shorter barrel reduces pellet velocity for longer-range waterfowl shooting. If you need rapid follow-up shots or maximum pattern density at 40+ yards, consider the Stevens 555 Sporting O/U 12 Gauge instead.
What's in the box?
You receive the complete takedown shotgun, one full choke tube, a choke tube wrench, and basic documentation. The package lacks any cleaning kit or additional choke tubes beyond the full constriction. For hunters needing modified or improved cylinder chokes, budget an additional $25-40 per tube from aftermarket suppliers.
Is the TPS Arms M6 Takedown worth it at $524.99?
At this price point, it represents solid value for shooters requiring NFA-compliant dimensions or extreme portability. The takedown mechanism adds approximately $75-100 over fixed-barrel equivalents while providing genuine utility for transportation. Compared to custom takedown conversions costing $800+, the M6 delivers 85% of the functionality at 65% of the price.

Frequently asked questions
- Does this work with .410 bore suppressors?
- Yes, the 18.25-inch barrel provides sufficient length for most .410 suppressor mounting systems. You'll need to verify thread pattern compatibility with your specific suppressor model, as thread pitches vary between ¾-16 and M18x1.0. Most major suppressor manufacturers like SilencerCo offer adapters for approximately $75.
- How long does shipping take to Montana?
- Standard shipping to Montana addresses takes 3-5 business days after the mandatory 3-day processing period. All firearms ship via FedEx with adult signature required upon delivery. Expedited 2-day shipping is available for an additional $35 through our premium service tier.
- Can I return it if it doesn't fit my case?
- Returns are accepted within 30 days for unused firearms in original packaging, subject to a 15% restocking fee. We recommend verifying case dimensions first—this shotgun requires a minimum 20-inch interior length when disassembled. Contact our support team with your case model for specific compatibility confirmation before purchasing.
- Is it compatible with aftermarket choke tubes?
- The M6 uses standard .410 internal choke threads compatible with most aftermarket tubes from brands like Carlson's and Briley. Tube replacement requires the included wrench and takes approximately 2 minutes with proper technique. Avoid over-tightening, as excessive torque can damage the barrel threads.
