This kit is designed as a drop-in replacement for the Nerf Infinus' stock trigger group, meaning NO SHELL CUTTING should be necessary for a proper fit.
Designed for the installation of three Cherry Microswitches (DC2 or DB1), allowing for a proper three-switch, MOSFET-compatible setup.
ALL PARTS included with download are required for proper installation of the kit. HOWEVER, the kit utilizes the stock firing trigger without requiring modification.
You will also need three (3) springs (~5mm OD): (1) for the firing trigger, (1) for rev trigger, and (1) for the fire control catch.
TIP: You can find these on Amazon in bulk, scavenge them from good quality pens, or reuse/stack springs from other blasters.
