PNW Air Dynamics

Sorta got these two working. SR25 is in a usable state (but every time you shoot it, it sounds like you put a fork down the garbage disposal) and the 416 upper and lower just dont want to mesh together completely, so the body pin wont go in. But it shoots, and shoots well. Very confused on both of these as I have spent the last two days trying to fix both issues, but have given up. I think the SR25 just needs new gears and bushings (stock sector and bushings) but the 416 I have no clue why it wont go together. I had this issue when replacing the inner barrel when i first got it, but that was solved with elbow grease

I got my two guns working again today. All i had to do was replace the nozzle on the AK and put in a new ARL on the M4. Need to iron out the smaller details, like finding a new stocl for the M4 and fixing the drum mag to feed the AK (works with midcaps so i think i might try a 9v battery first).

M4 is 9t SP170 (1.5J expected)
And AK is 8t SP160 (1.3J expected)

Progress over the past two days:

Got heatshrink over the fets and sealed them.
Prepped the trigger contacts and all the wires for them. Trigger contacts will get wires on them tomorrow, deans will be put on this weekend, and then it's testing and packing.
