.22 [AirMaks Arms] Katran SC Ultra Kit

Kit Notes:

The AirMaks Arms .22 Katran Sub-Compact Ultra Kit is a high-performance, ultra-lightweight PCP (pre-charged pneumatic) air rifle package designed for tactical shooting, hunting, and pest control.

Built by the Czech manufacturer AirMaks Arms, the core of the kit is the Katran SC model in .22 caliber (5.5mm), which emphasizes portability, accuracy, and modularity. It's particularly praised for its compact size, making it easy to carry in a backpack or vehicle, while delivering consistent power for short- to medium-range applications like ratting or target practice out to around 50 yards.

Key Features and Specifications

• Design and Build: The Katran SC features an ergonomic AR15-style right-hand grip (with ambidextrous options available) for comfortable handling. It has a detachable, length-adjustable aluminum stock with a height-adjustable cheek-piece and butt-pad for customized fit. The stock includes built-in holders for spare magazines. Without the stock, it can function as a pistol-like carbine, enhancing its versatility.
• Dimensions and Weight: Extremely lightweight at just 1.6 kg (about 3.5 lbs), it's one of the lightest in its class. Overall length is 694 mm (27.3 inches) with the stock attached and 448 mm (17.6 inches) without, allowing it to fold compactly for storage or transport.
• Barrel and Accuracy: Equipped with a 230 mm (9 inches) CZ cold-hammer-forged barrel with a 1:17.7 twist rate, optimized for .22 pellets. It's known for excellent accuracy, with users reporting tight groupings at close ranges (e.g., 20-30 yards) and reliable performance for sub-12 ft/lbs setups in regions with power limits.
• Air System: Features a 100 cc aluminum air cylinder with a maximum fill pressure of 300 bar (about 4,350 psi). It includes an adjustable pressure regulator and external velocity adjustment via a hammer spring screw, allowing tuning for different pellets or power levels.
• Magazine and Capacity: Comes with a 16-shot rotary magazine in .22 caliber for smooth, quick reloading.
• Trigger and Safety: 2-stage adjustable trigger for precise control, paired with an AR15-style safety switch that's reversible for left- or right-handed use.
• Action: Side-lever cocking mechanism that's easy to operate and switchable between sides.
• Mounting Options: Integrated 20 MOA Picatinny rail for optics, plus a 1/2" UNF threaded muzzle for attaching moderators. The air cylinder cover has multiple threaded holes for additional Picatinny rails.
• Performance: Tunable for consistent shot strings, with typical velocities around 800-900 fps depending on pellet weight and regulator settings. It's quiet by design, especially with a silencer, and offers good shot count per fill (around 40-50 shots in tuned configurations).
