M16 double firing
M16 double firing
Hey everyone! I have a JG M16. I removed the hop-up from the barrel and when I put them back together, it double fired, meaning two bbs came out when I pulled the trigger. Should I buy a new hop-up or would a new hop-up bucking do the job?
Re: M16 double firing
You *may* have torn your hopup bucking. Did you use any sort of lubricant when you put it back together? Have you only fired the gun once, or is it repeatedly double-feeding?
Unless you broke the actual unit (which is unlikely), a new bucking should fix it. Don't buy anything until you've confirmed that the bucking you have is installed correctly and is/isn't ripped.

Yeah I put it back together correctly...it might be torn,but I don't know. The hop-up unit seems to be fine.

I'm using .20s. I shot fine till I took it apart...
Re: M16 double firing
When you reinstalled the chamber and barrel, you did not properly align them with the GB and thus the airnozzle has a little bit of extra space between it and the bucking lip, causing a consistent double feed. 80% chance that's it, otherwise you may have broken it or misplaced it some other way, like misaligning the bucking, chamber, and/or barrel in some manner.

Dom is the expert here, but you could start by making sure the small spring is still on the front of the hopup unit; it ensures that it pushes back against the air nozzle.

Re: M16 double firing
Yeah that is missing...would that actually make it double fire? Thanks for the help!

Re: M16 double firing
It is actually a very simple, yet very common error. And yes it very easily can cause double feeding.cripto wrote: Yeah that is missing...would that actually make it double fire? Thanks for the help!

Re: M16 double firing
Yep, missing that spring causes that "little bit of extra space" I was talking about. That's the problem.
