So a little while ago I asked how to reduce the FPS on a WE Scar-L GBB, I got some great advice but my friend told me to get the Poseidon 'Zero 2 Plus adjustable Loading Nozzle'. This worked really great however I had a small problem with it.
There is an incredibly small bolt that you adjust it with that's in the nozzle, i'd say about 2.5mm long and like the idiot I am I screwed it in too far causing it too fall inside the nozzle lol.
After painfully prying it to get it back in it's thread and screwing it in it's place, I wasn't paying attention and installed the nozzle wrong, causing it to break.
But then my buddy came with the genius idea to just drill a small hole into the original nozzle, tap some thread into it and just screw a new bolt into that one, and it works perfectly.

If anyone does this, use a 6mm bolt instead of the really short one, it'll allow you to adjust it further without dropping the damn thing in the nozzle. The Zero 2 Plus loading nozzle is 75 "euros" for me with shipping costs so it will also save a lot of money. If anyone here has a ScarL/ScarH GBB and wants to do this and you need more info or pictures just DM me and I can show you.
Hopefully this is actually useful because to me it most certainly was.
