Umarex Zelos is a powerful PCP air rifle particularly suitable for precise target shooting at longer distances. Thanks to a good combination of features such as a large-capacity magazine, threaded muzzle for a suppressor, compact dimensions and simple handling, the air rifle is also ideal for recreational plinking in the garden or hunting small pests.

Barrel, PCP system and controls
The rifled barrel reaches an impressive length of 680 mm. Nevertheless, the air rifle still maintains a compact overall length of only 926 mm thanks to the bullpup design, where the barrel begins already under the cheek rest. The barrel is shrouded along its entire length and at its muzzle there is a 1/2″-20 UNF thread for optional installation of a sound moderator.
This air rifle is equipped with an aluminium air cylinder with a capacity of 255 cc and a maximum filling pressure of 250 bar (3625 psi). A significant advantage is the externally adjustable pressure regulator (range 1000 - 2000 psi / 69 - 138 bar), ensuring consistent muzzle velocity. The current pressure is indicated by 2 pressure gauges - one showing the pressure in the air cylinder, the other the pressure in the regulator. The air rifle can be filled via a standard quick-coupler adapter hidden at the end of the cylinder.
The very smooth-operating side lever is fixed on the right side, as is the rotary manual safety. The two-stage trigger allows adjustment of the height and rotation of the trigger blade, and when the trigger mechanism cover is removed, the trigger travel can also be adjusted.

Construction and ergonomics
The main body of the gun, the top Picatinny rail and the barrel shroud are made of black anodized aluminium. All this is complemented by polymer components such as the trigger mechanism cover, fixed cheek rest and lower Picatinny rail for mounting a bipod or other accessories. The comfortable rubber butt pad is height-adjustable, and the manufacturer has also opted for a rubberized AR-15 style grip, so you can replace it with another one at any time.
