Help with my arp9 project build

[steverebo]

I have an arp9 that is my project gun that I bought with a dead mofset I have replaced the trigger and mofset with a perun v2 hybrid added some 13:1 gears that are short stroked by 3 teeth a new compression set and thrust bearing spring guide, 155mm prometheus barrel and I've stuck with the stock motor. It came with an m115 spring in it and with .25 I was getting 263fps so I have ordered a m125 spring to bring me up to 295 ish. 

I'm having an issue where the nozzle rests in the pre cock position no matter what level of active breaking I use I even tried decock and still no luck

When I shoot the nozzle stays retracted like it is precocking

It's normal.

The nozzle stays retracted when "at rest".

Nothing to worry about.
