AAP-01 Short stroke bouncer kit with 300procent nozzle return spring

<p>We tested 150, 200, 230procent variation springs with most leading buckings.. But our <strong>300procent gave 100procent feeding consistency</strong> in most SS (short stroke) applications. </p>
<p>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”.</p>
<p>This material property lessens the shock to the rear sight assembly.</p>
<p>As used by numerous YouTube airsofters across the globe. Install, and welcome to the <strong>BRRRTTT</strong> family.</p>
