Hi guys, bit of a newbie here!
I recently took look at the air nozzle of my airsoft gun ( i didn't take the air nozzle out of the gun or anything like that, the air nozzle is still where it is where it is when you take at your inner barrel and are left with the lower receiver) While doing so, I noticed that i could twist the air nozzle around clockwise, until the point where the air nozzle was reasonably tight, then i twisted it more and the nozzle became loose again ( this is just the little but that sticks out and connects with my hop up). I was just checking to see if this is normal or something is wrong, and wether i should twist the air nozzle until its tight and leave it like that or leave the air nozzle so it can freely move around? Thanks very much guys!
