Description
North American Arms built its reputation on tiny single-action revolvers, and the Ranger II is where that formula gets interesting. Instead of pulling the cylinder pin to reload like the classic minis, this one breaks open at the top, and a star ejector kicks all five empties out at once. That single change makes the gun far quicker to reload and a lot more pleasant on a range day. This version stretches the barrel to a full 4 inches with a ribbed top and a bead front sight, so you get usable sight radius and better velocity out of the .22 WMR cartridge without giving up much in the way of packability.
Why the 4 Inch Ranger II Stands Apart
The longer barrel came about because owners of the original short Ranger II kept asking for it, and NAA delivered. The extra length helps the .22 Magnum round do its job, whether that is trail carry, dispatching pests around the property, or serving as a lightweight backup. Construction is stainless steel throughout with a bead-blasted satin finish, and the rosewood boot grips give it a classic look that draws attention at the counter every time. At roughly 8 ounces, it disappears in a pocket or pack pouch and you will forget it is there until you need it.
Simple, Safe Single-Action Operation
Like every NAA mini revolver, the Ranger II uses half-way notches between the chambers, so the hammer can rest securely with all five rounds loaded and no chance of a blow to the hammer setting one off. Loading and unloading happens with the hammer at half cock, and the whole manual of arms takes about two minutes to learn. If you want cheaper practice sessions down the road, NAA offers a .22 LR conversion cylinder that the factory can fit and time to your gun. The Ranger II 4 inch is one of those pieces that ends up being both a working tool and a conversation starter, and very few guns pull that off.

Frequently Asked Questions
Does the NAA Ranger II 4" come with a .22 LR cylinder?
No, this model (NAA-22M-R4) ships with the .22 WMR cylinder only. NAA sells a .22 LR conversion cylinder separately, but it needs to be timed and fitted by the factory, so plan on sending the revolver in or contacting NAA directly to have that done.
Is the Ranger II safe to carry with all five chambers loaded?
Yes. The cylinder has half-way safety notches machined between the chambers, so the hammer can rest in a notch rather than on a live round. Carried this way, an impact on the hammer will not discharge the gun, which is a signature feature of NAA mini revolvers.
How is the Ranger II different from other NAA mini revolvers?
The big difference is the break-top action. Classic NAA minis require you to remove the cylinder from the frame to load and eject each case individually. The Ranger II tips open at the top and its star ejector kicks out all five empties at once, which makes reloads much faster and range time a lot easier.
What is the 4 inch barrel version good for?
The longer full-rib barrel adds sight radius and squeezes more velocity out of the .22 WMR round, so it points and shoots noticeably better than the shorter minis. Owners use it as a trail and tackle box gun, for small game and pest duty, and as a lightweight backup that still tucks away easily at around 8 ounces.
