Our full review of the Zbroia Kozak MK2
At just 715mm and three kilos unscoped in its shortest configuration, the Kozak is compact and light, making it ideal for hunting and pest control, especially around farm buildings and woodland. The butt pad has no adjustment and is finished with a tasteful red spacer. However, the cheekpiece can be adjusted for height by slackening a gold coloured screw in the butt.
The adjustment is slightly sprung, making fine adjustment easy to achieve. The ambidextrous stock is available in either a black or brown stain finish and although there is no chequering, grooves in the forend make the Kozak easy to hold. The side lever operates from the right side of the rifle and has a gold coloured drop down biathlon style handle. The action is not sprung but moves smoothly to cycle pellets through the 10 shot (.22) / 12 shot (.177) disc magazine, two of which are provided.
The gold trigger is two-stage and can be adjusted by taking the stock off. There is a clear stop before the second stage which lets off crisply. A small safety catch is located forward of the trigger; push it forward to make the rifle live and back to make it safe. The trigger guard itself is plastic and connected only at one end; make sure you don’t snag the open end on your clothing.
Shrouded for most of its length, the barrel has a ½ inch UNF thread to accept a silencer, although the Kozak is very quiet without one. A 180mm picatinny rail provides plenty of space to fit a scope. The rifle comes with two filler probes. One is threaded and the other is designed to snap straight on to a quick fit style connector. Filling the Kozak is achieved by rotating a collar at the front of the air cylinder against a stop to reveal the port. Zbroia states that the Zozak will accept a 300 bar fill. However, I found a 200 bar fill was good for around 120 accurate .177 shots in the 200cc test rifle. A pressure gauge located under the muzzle shows how much air is left.
