BullMaster, a semi-automatic multi-shot PCP air rifle from Hatsan Arms. It features a Semi Auto Action system, which provides automatic reloading after each trigger pull (only in FAC* version). SemiAutoAction allows for rapid, accurate shots at long distances without the need to adjust/correct the aiming line after each shot. Available in calibers: .177 (4.5 mm), .22 (5.5 mm), .25 (6.35 mm).
Power supply - a fixed compressed air reservoir with a capacity of 500 cc (air tube bottle) and 30 cc (air tube). A fully charged cartridge allows for 100 to 120 shots, depending on the caliber of the air rifle (data for the FAC* version). The manometer allows for continuous monitoring of the pressure in the tank and thus its charge level. Due to its large capacity, charging is only possible from a technical or diving cylinder (300 bar). 130 bar is the minimum operating pressure in the cartridge necessary for the proper functioning of the air rifle with the Semi Auto Action system.
Barrel - fully covered with a metal shroud. Precision rifled barrel with a length of 19.7" (500 mm), Hatsan Arms. The narrowing at the barrel's muzzle, called a choke, improves accuracy. The quality of the barrel's craftsmanship is one of the most important elements of any firearm/air rifle. It affects the rifle's accuracy, especially when shooting at long distances.
Stock - bullpup type with a TH (ThumbHole) opening, suitable for both right- and left-handed users. Thanks to the bullpup design, compact rifle dimensions have been achieved while maintaining a normal barrel length, ensuring excellent accuracy and the reduced recoil typical for this design. Made of durable, damage-resistant polymer in black. Two sockets for 2 spare magazines. Rubber ventilated butt pad and height-adjustable cheek rest.
Mounting rail - tactical version of the air rifle without sights, with an extended, double mounting rail 11 mm / 22 mm, allowing for the installation of any optical sight. The rail complies with the MIL-STD 1913 standard (also known as picatinny or Weaver). An additional picatinny rail is located on the bottom of the stock.
Magazines - multi-shot Clip Magazine-A with a capacity of 10 to 14 pellets, depending on the air rifle's caliber. Three magazines are included in the set.
Bluing - the breech block is covered with a blue finish bluing.
Additional equipment - two metal swivels for attaching a gun sling or tactical sling. A Quick-Fill tip for quick filling of the cartridge with air from a cylinder (300 bar). The whole set is packed in a rigid polymer case.
The BULLMASTER air rifle is equipped with several solutions to improve comfort and safety of use:
-
EasyAdjust system for adjusting the height of the cheek rest. The stock is equipped with an integrated button for adjusting the cheek rest's height.
-
Anti-Knock System® - patented system preventing compressed air loss in case of mechanical impact to the air rifle.
-
Manual safety, prevents unintentional firing.
