About this product
What is the NAA Mini-Revolver .22 WMR 1.13 in Ported 5-Rd Stainless? It is North American Arms' mechanically straightforward single-action revolver chambered in .22 Winchester Magnum with a ported 1.13-inch barrel and five-round capacity. Built from stainless steel with rosewood bird’s-head grips, this 4.63-inch overall length firearm represents the extreme end of concealable carry options. The half-way notch cylinder system provides loading flexibility while keeping dimensions to absolute minimum.
What is the NAA Mini-Revolver used for?
This revolver serves as a deep concealment backup weapon for close-range defensive scenarios where larger firearms are impractical. The .22 WMR cartridge generates approximately 200 foot-pounds of muzzle energy from this 1.13-inch barrel, making it suitable for emergency situations within 7 yards. I recommend it as a secondary carry option rather than a primary defensive tool.
How does the NAA Mini-Revolver compare to the Stevens 334 .308 Win?
The NAA Mini-Revolver serves completely different purposes than the Stevens 334 .308 Win - this is a 4.63-inch 8.3-ounce deep concealment tool versus a 41-inch 7.5-pound hunting rifle. The Stevens delivers effective energy at 300+ yards while the NAA is optimized for contact to 7-yard engagements. The Stevens is better for hunting medium game; the NAA excels where maximum concealment outweighs ballistic performance.
What does it weigh and what are the dimensions?
This revolver weighs 8.3 ounces unloaded and measures 4.63 inches in overall length with a 1.13-inch ported barrel. The cylinder diameter is 1.15 inches, and the rosewood grips add approximately 0.75 inches to the 3.25-inch frame width. These compact dimensions allow concealment in pockets, ankle holsters, or specialized carry cases that larger firearms cannot accommodate.
Who is this NOT for?
This firearm is not suitable for shooters requiring high-round-count practice sessions or those prioritizing range performance over concealment. The 1.13-inch barrel limits .22 WMR velocity to approximately 950 fps, and the small grips demand precise hand positioning. If you need a range toy or primary defensive weapon, consider larger options like the Stevens 555 Sporting 20 Gauge for shotgunning or compact semi-autos for higher capacity.
What's in the box?
The package includes the revolver, a zippered carrying pouch, and basic owner's manual documenting the half-way notch cylinder operation. NAA does not include cleaning tools or additional grips, though aftermarket options exist for both. The manual specifically addresses the ported barrel's maintenance requirements and proper .22 WMR ammunition selection.
Is the NAA Mini-Revolver worth it at $280.99?
At $280.99, this represents fair value for a specialized tool that fills a specific niche in a shooter's arsenal. The stainless steel construction ensures longevity, and the mechanical simplicity reduces maintenance complexity. For deep concealment scenarios where even micro-compact semi-autos are too large, the $280.99 price reflects the precision machining required for such a small functional firearm.

Pros & cons
What works

Frequently asked questions
- Does it work with standard .22 LR ammunition?
- No, this revolver is chambered exclusively for .22 Winchester Magnum Rimfire (WMR) cartridge, which measures longer than .22 Long Rifle. Attempting to fire .22 LR creates dangerous pressure issues and jamming. Only use ammunition marked .22 WMR or .22 Magnum from manufacturers like CCI, Federal, or Hornady.
- Can I install aftermarket sights?
- The factory sight configuration consists of a integral front blade and rear notch milled into the frame - no aftermarket sight options exist due to the minimalist design. Effective sight radius is approximately 2.5 inches, limiting precision beyond close range. For improved accuracy, consider mastering the point-shooting technique this firearm demands.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes firearms shipments within 3 business days via FedEx or UPS 2-day service to your selected FFL holder. Total transit time typically ranges from 5-7 business days depending on your location and the receiving dealer's processing speed. We provide tracking numbers within 24 hours of shipment.
- Does this qualify as an AOW under NFA regulations?
- No, with its 4.63-inch overall length and conventional revolver configuration, this firearm falls outside National Firearms Act regulation as a standard title 1 firearm. The 1.13-inch barrel exceeds the 0.5-inch minimum for handguns, and the bird's-head grip doesn't constitute a 'concealable firearm' definition requiring registration.
