The Spring Trigger. A spring trigger is actually a small spring with a threaded end that replaces the hard trigger on specially made index-triggered releases. Because it bends when you pull it, the spring is very difficult to punch. Your only recourse is to keep pulling as you continue to aim at the spot you want to hit.
Spring Piston Performance. The spring piston airgun generates power using a powerful spring-loaded piston that is housed within a compression chamber. Cocking the gun (using a break barrel, side lever, or under lever mechanism) causes the piston assembly to compress the spring.here are many options available when it comes to the selection of a spring piston air rifle for hunting. The one that is best suited for you depends on what you want to hunt, where you will hunt, what ranges youâll shoot at, and of course, which rifle appeals to your sense of aesthetics.
