Hadron 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.

The short stroke segment, is made from a bouncy material, effectively taking the impact of the bolt, and bouncing it back. Hence why the nickname this kit, the "Bouncer".

This material property lessens the shock to the rear sight assembly.

Please note, there is a small solid tube as part of the segment, which is removed before fitting into the rear spring assembly.
