Hatsan AT44-10 TACT Air Rifle (6.35mm / .25 Cal)

The Hatsan AT44-10 TACT (Tactical) takes the highly proven reliability of the standard AT44 PCP platform and re-engineers it into an aggressive, modular layout. Optimized for the heavy-hitting 6.35mm (.25 caliber) pellet, this rifle is designed for shooters who demand high-impact field performance paired with ultimate tactical adaptability.

The defining feature of the TACT model is its removable Tactical Telescopic Stock. The M4-style buttstock can be adjusted across multiple positions to perfectly match your length of pull, or it can be completely detached from the rifle—allowing you to operate it as a highly compact, maneuverable platform using only the ergonomic synthetic pistol grip. Designed for extended time in the field, the stock features on-board storage slots to hold two spare rotary magazines right under the cheekpiece. With three integrated Picatinny accessory rails wrapped around the forearm, a gold-plated adjustable Quattro Trigger, and a natively threaded muzzle ready for an external silencer, the AT44-10 TACT stands as a premier, customizable powerhouse for serious pest control and tactical shooting.
