*URGENT* Glock style feeding nozzle spring
 

So I have a WE M&P 9 big bird custom. It has the same internals as any semi only glock, my problem is that I’m the feeding nozzle housing, the spring does not stay in where it should, does anyone know a fix to this ?

Are you trying to reinstall the blowback unit?

Stop drinking so much Monster and steady your hands so that when you put in the blowback unit it doesn't shake. Keep the nozzle retracted as much as possible and don't freak out if it moves out of place when installing it.

im guessing its the compression spring type.
Just don't turn the BBU upsidedown, lift it up into the slide, don't drop it into the slide.

I've found on slides that have a loose mock shell extractor that it's best if you kinda slant the slide and turn it half on its side to keep the extractor in place then slide the BBU in works best.
