Hadron Airsoft Designs - AAP-01 Short Stroke Bouncer Kit with 300% Nozzle Return Spring
This is the AAP-01 Short stroke kit, including a Hadron Designs specific 300% upgraded recoil spring and helps the system to cycle quicker.
This kit for AAP01s tested 150, 200, 230% variation springs with most leading buckings. But their 300% gave 100% feeding consistency in most SS (shortstroke) applications.
The shortstroke segment springs can create incredible results and is made from a bouncy material, effectivley taking the impact of the bolt, and bouncing it back. Hence why we nickname this kit, the "Bouncer".
This material property lessens the shock to the rear sight assembly.
