[Hectic]

So today i was fielding my we 416 OB and the spring in the nozzle (nozzle return spring i spose its called) apparently broke at the nozzle end and got jammed up behind the nozzle in the bolt.
I had to actually remove the hop up unit to get the bolt to go forward enough to even remove the upper.
So i figured i could add a new loop on it and put it back but because its so mangled i cant quite get the loop to go into the lil slot to hold onto the pin in the bolt.
So is there a suitable replacement spring available for this or do i need to buy a whole nozzle to get a spring from.
Also is the a relatively normal failer or is there another problem causing this.
Like i have noticed the nozzle sticks a lil in the hop up (as tho the hop is a lil twisted) could this cause premature spring breakage?
