Arp 9 / 556 Speed trigger

Designed this speed trigger for ARP9 /ARP556 and it works perfect.

Print it like shown in the third picture and file down the inner corners a bit where it sits on the trigger, the FDM printer can't make crisp coners.
If u print it in tough resin, u dont have to file anything.

Use the existing screws from your Arp9 and u ready to go. But i would recommend buying a speed trigger.

Happy printing and happy shooting.
