Description

The Mini-Master sits at the top of the North American Arms lineup, and it is the one to grab if you want a mini-revolver you can genuinely shoot well. Built on NAA's proven .22 Magnum frame, this version stretches things out with a 4-inch heavy vent rib barrel and a full bull cylinder, which adds just enough weight up front to steady the gun and tame what little recoil there is. This model is the conversion package, so you get two cylinders: one for .22 Magnum and one for .22 Long Rifle. Run cheap LR for plinking sessions and swap to Magnum when you want more pop, all in about a minute with no tools.

Why the Mini-Master Shoots Better Than It Looks

Most pocket-size rimfires ask you to aim with a groove and a prayer. Not this one. NAA fits the Mini-Master with Marble Arms adjustable sights, so you can dial in your elevation and print real groups at the range instead of guessing. The oversized finger-grooved rubber grip fills the hand far better than the tiny bird's head grips on the smaller minis, giving you a repeatable hold shot after shot. All in, it runs about 10.7 ounces and just under 8 inches overall, so it still disappears into a pocket or kit bag.

Simple, Sturdy, and Built to Last

The whole gun is stainless steel, frame to muzzle, so sweat, humidity, and a life spent in a tackle box or truck console will not wear on it. The action is single action only, cocking the hammer for each shot, and the cylinder has NAA's halfway notches that let you rest the hammer safely between chambers with all five rounds loaded. It is a wonderfully simple machine with very little to go wrong.

Where the NAA Mini-Master Earns Its Keep

This is a fun gun first and a serious tool second. It makes a great trail and tackle box companion, a conversation starter at the range, and a deep-concealment option for folks who appreciate small, mechanically honest revolvers. Between the two calibers, the adjustable sights, and the stainless build, it is the most versatile mini-revolver NAA offers.

Frequently Asked Questions

Does the NAA Mini-Master come with both cylinders?

Yes, this is the conversion model (NAA-MMT-C), so it ships with a .22 Magnum cylinder and a separate .22 Long Rifle cylinder. Swapping them takes about a minute and requires no tools, just remove the cylinder pin and drop in the other cylinder. It is an easy way to shoot inexpensive LR for practice and step up to Magnum when you want it.

Is it safe to carry the Mini-Master fully loaded?

Yes. NAA machines halfway notches between the chambers on the cylinder, and resting the hammer in one of those notches keeps it completely off any cartridge rim. That lets you carry all five rounds loaded with the hammer down safely, which is a signature feature of NAA mini-revolvers.

How accurate is the Mini-Master compared to smaller NAA minis?

Noticeably better. The 4-inch heavy vent rib barrel adds sight radius and muzzle weight, the Marble Arms rear sight adjusts for elevation, and the oversized rubber grip gives your whole hand something to hold onto. Owners regularly report it shoots far more like a real range gun than its pocket-size siblings.

How does the single action work on this revolver?

The Mini-Master is single action only, meaning you manually cock the exposed hammer for every shot before pulling the trigger. It is a simple, time-tested design with very few moving parts, which is a big part of why these little stainless revolvers have such a reputation for durability.
