In all forms of the so-called spring tensioners, a piston located in a cylinder is tensioned against a spring within the weapon system and locked in place, which is suddenly released by pulling the trigger, driving the piston through the cylinder. This creates an air cushion that propels the projectile through the barrel of the weapon.
In underlever tensioners, the tensioning and locking of the piston against the spring is done by a lever mounted below the weapon.
The preference for a specific tensioning system in spring tensioners is often a matter of taste. Underlever tensioners are perceived by many as handy and easy to operate, and therefore enjoy a certain popularity.
The costs for an underlever tensioner vary just as much as with other types of weapons. Manufacturer, model, condition, etc. are decisive for the price.
Most underlever tensioners are priced in the mid three-digit to low four-digit range when new.
If one wishes to acquire, own, or carry a firearm, a corresponding firearms permit is required. The acquisition and possession of blank-firing, irritant, and signal weapons is permit-free for individuals who have reached the age of 18. However, a small firearms license is required to carry these weapons. Air pressure weapons, spring-piston weapons, and CO2 weapons are also available from the age of 18.
