Although it may not seem so at first, the Reximex Lieva is a standard PCP air rifle with all the features found in the most modern air rifles.
The overall design of the air rifle is heavily inspired by iconic wild-west lever-action repeater rifles. Therefore, instead of biathlon-style cocking mechanism, it features a bottom lever-action lever, which is additionally wrapped in a hand-tied leather strap to increase comfort during reloading.

However, this is where all similarities with historical guns end. Strangely enough, the 520mm barrel is actually positioned under the cartridge and is finished with a 1/2 UNF thread for installing a sound moderator, the aluminium cartridge with a volume of 105cc can be pressurized to up to 250 bars, and lead pellets are not loaded into the body of the rifle but either into a standard spring-loaded magazine or a single-shot adapter. Another great feature is the built-in pressure regulator, which ensures consistent muzzle velocity from full pressure to the regulator's limit of 100 bar. This results in higher accuracy and lower air consumption.
The Classic sights are horizontally adjustable, or you can remove the rear sight and replace it with a riflescope thanks to the 11mm Dovetail rail. To adjust the trigger length, you will need to remove the stock using four screws.

Regarding safety features, there is nothing to speak of - the air rifle does not contain any safety mechanism, so to fire it, you only need to pull the cocking lever.
As for the materials used, the manufacturer completely avoided plastics except for the buttpad. Everything else is made of black anodized aluminum and the stock and forearm are made of Turkish walnut. The air rifle thus feels very high quality and, despite its compact dimensions, weighs 2200 grams.
