Description
The Mauser TacOps PK 22 LR is a tactical-style rimfire pistol built for Mauser and imported by Blue Line. This is Mauser model 4150043, UPC 689585856587: a 22 LR semi-automatic with a 5-inch black anodized barrel, a Picatinny rail on top for optics, a black aluminum frame with a lower accessory rail and a 22-round magazine.

Mauser TacOps PK 22 LR Overview
The TacOps PK takes the compact, rail-covered look of a modern tactical pistol and pairs it with inexpensive 22 LR ammunition. The top rail makes it easy to mount a red dot, and the lower rail takes a light or laser, so you can set it up for fast target shooting or simply have fun on the range without the cost of centerfire ammunition.
Top Rail for Optics
The full-length Picatinny rail on top of the receiver accepts red dots and small scopes without extra mounts. A red dot makes it easy for new shooters to get on target quickly and is a great match for steel challenge style practice.

Lower Accessory Rail
The lower rail on the aluminum frame takes a weapon light, laser or hand stop, so you can configure the pistol the way you like. It also gives you a place for a forward grip accessory where legal.
22-Round Magazine
The 22-round magazine means fewer reloads and more shooting. Spare magazines keep range days rolling, and the light recoil lets you run through them quickly with good control.
Affordable Practice
Rimfire ammunition costs a fraction of centerfire, so you can practice sight alignment and trigger control far more often without straining the budget.
Setting Up an Optic
A small red dot is the most popular upgrade. Mount it on the forward part of the top rail at a height that lets you see the dot naturally when you extend the pistol, then zero at 10 to 15 yards. Many shooters find a dot speeds up target transitions and makes it easier to teach new shooters where to aim.
Plinking Ideas
Hanging steel, dueling trees, spinners and even old soda cans make great targets for a rimfire pistol. Set up a simple course of fire with a few targets at different distances and time each other for some friendly competition, always following range rules and safe backstops.
Choosing Ammunition
Rimfire pistols run best with quality high-velocity 36 to 40 grain round nose ammunition. Try a few brands, note what feeds and groups best, then stock up on that load.
Range Day Checklist
Bring eye and ear protection, a few hundred rounds and a spare magazine. Reactive steel targets and spinners make practice more fun, especially for new shooters.
Teaching New Shooters
A light, quiet pistol with almost no recoil is an excellent teaching tool. Start close with large targets, focus on safe muzzle direction and finger discipline, and keep sessions short and fun.
Cleaning and Maintenance
Clean the breech face, extractor and chamber every few hundred rounds, keep a light coat of oil on the moving parts, and check magazine lips if you see feeding issues.
Safe Storage at Home
Whenever a handgun is not in use, keep it locked in a safe or lockbox, especially if children live in or visit your home, and store ammunition separately.
