Key Features
- One-Button Takedown — Press one button and the upper lifts off the grip frame. This means you can field-strip and clean the Mark IV in seconds, no tools or frustration.
- Threaded Bull Barrel (1/2x28) — The 5.50-inch bull barrel is threaded so you can attach a suppressor or compensator. It reduces recoil and muzzle rise, helping you stay on target for faster follow-up shots.
- Adjustable Rear Sight — Windage and elevation adjustments let you dial in your point of aim precisely. This matters when you're trying to punch tight groups at 25 yards.
- Two 10-Round Magazines — Spare magazine means less reloading at the range. Each mag feeds .22 LR reliably, and the extended base pad makes seating easier.
- Satin Stainless Finish — Corrosion-resistant and easy to wipe down after a wet day at the range. No rust worries, even if you shoot in humid weather.
Who It's For
This pistol is for anyone who wants a dedicated .22 LR target gun that's accurate out of the box. It fits new shooters learning fundamentals, experienced marksmen working on trigger control, and suppressor owners who want a quiet host. The threaded barrel also appeals to hunters who need a low-noise option for small game.
Pros & Cons
- Pro: The one-button takedown is a real time-saver — you can clean it in under a minute.
- Pro: Satin stainless finish holds up well against sweat and solvents.
- Con: The grip angle is steep, and some shooters find it less natural than a 1911-style frame. An aftermarket grip adapter can help, but it's an extra cost.
