Product Description
Hadron Airsoft Designs - AAP-01 Short Stroke Bouncer Kit with 300% Nozzle Return Spring
AAP-01 Short stroke kit, including a Hadron Designs specific 300% upgraded spring.
They 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, 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.
