Hi All,
Been a while, so I was dusting my guns of to make sure they worked. I tried to shoot my M4, but no bbs would discharge. I could feel air coming out of the barrel, and took off the front-end to feel air coming out of the nozzle. BBs were loading (tried different mags) and barrel was clear. After about an hour I looked down the hop-up cylinder loading from the mag well and noticed the air nozzle is covering the hole (so no bbs actually make it into the barrel. I can push on the air nozzle and it moves a little less than half an inch. The hop-up is mating up to the rest of the gun (where the air nozzle is inserted).
Any clue why the air nozzle is intruding so far into the hop-up?
I can't see anything that should be holding the air nozzle back.
Nozzle depressed
Nozzle covering entry of bbs into barrel

Re: CA CQB Seal M4 not shooting bbs
The air nozzle always covers the entrance, when the tappet plate pulls it back it allows a BB to come up, then it pushes it forward into the hopup unit. The fact that it is blocking the chamber in it;s resting state is a good thing. The question then is, does it come back all the way when you cycle the GB?

Re: CA CQB Seal M4 not shooting bbs
Yep, I just watched a video on that. And, no it is no moving, allowing a bb to be loaded. There is resistance, when I push on the air nozzle it goes back to place. Would that mean the tappet plate could have come off the sector gear?
Just weird, it was working fine when I put it away a while ago.
I'm just trying to figure out if I should take the gear box apart (which I've never done before). The gear box has not been opened since I bought the gun back in 2006.

Re: CA CQB Seal M4 not shooting bbs
The air nozzle can always be moved manually, so I'd put my money on a broken/screwed up tappet plate.
Re: CA CQB Seal M4 not shooting bbs
def a broken tappet plate not uncommon with that era of CA's

Re: CA CQB Seal M4 not shooting bbs
that was my thought.
Re: CA CQB Seal M4 not shooting bbs
Though it is most likely that the tappet plate is broken, there is a small possiblity that the airnozzle simply slipped out of the tappet plate collar. If so, it must simply be put back in. Go ahead and assume that the tappet plate is broken though[/b].Straightshot wrote:Yep, I just watched a video on that. And, no it is no moving, allowing a bb to be loaded.

It can not come off, but it can break.

When tappet plates go, they go.
