Tactical PCP Air Rifle

Ozark-TS features a tactical stock made of durable polymer, complete with a pistol grip and a telescopic AR-15-style buttstock with an adjustable cheek rest. The receiver is machined from aircraft-grade aluminum.

The rifle is operated via a fast and user-friendly biathlon-style side lever cocking system, conveniently located on the right side of the action.

In addition to the optics rail, a 22mm Picatinny accessory rail is located under the barrel — ideal for mounting the included bipod or a tactical flashlight.

Precision Barrel & Dual Air Reservoir

The rifle boasts a precision rifled barrel measuring 21.65" (550 mm) in length. Choked at the muzzle for improved projectile stabilization and accuracy, the barrel ends with a 1/2" UNF external thread, ready for a suppressor or muzzle brake.

Ozark-TS features a 425cc high-capacity air reservoir pressurized to 250 bar. Together with the Anti-Hammer Bounce system, it enables extended shooting sessions — up to 144 shots per fill (in the FAC version).

Advanced Technologies

All Niksan PCP rifles come standard with Anti-Hammer Bounce technology, which prevents secondary hammer impacts on the valve stem, effectively minimizing air loss and increasing shot efficiency.

Ozark-TS includes a fully adjustable trigger unit with settings for both pull length and trigger weight. The 3D trigger blade allows for fine-tuning of height and angle to match the shooter's grip and style. A manual safety located above the trigger ensures safe operation.

The rotary-indexing magazines hold between 10 and 14 pellets depending on the caliber. The set includes a total of 4 magazines.

A built-in transfer port valve allows for energy adjustment and can be upgraded to a high-performance (HP) version for tuning — a feature inspired by Reximex rifles.

The set also includes a durable polymer hard case and a bipod for enhanced shooting stability.

For all air rifles limited to 17J, the manufacturer includes a unique 17 Joule Energy Limit Certificate. This document certifies the product’s specifications and ensures compliance with Polish regulations.
