SHS nozzle is just a tad longer than other M4 nozzles, but I've never had feeding issues from the SHS nozzle being longer. I've used SHS nozzles in both of my VFCs.

Also, if 395 fps is your goal you can do it with a M110 if your air seal is perfect (even with 3 teeth SS)

I mentioned to another helpful hand above that more often than not the nozzle is a few mm into the magwell, preventing it from feeding, BUT I have seen it a few times go all the way back, which means its not too long, therefore must be another problem. I will cycle it as you said and get it in the rear position and see if a bb slides down inside. If it does, what does that mean? Do we go back to the overspin stopping at random different intervals, therefore putting the nozzle in different places and unable to feed?

Other than an AB mosfet, would using bushings rather than bearings make a difference? (I know it will slow the gears down slightly, but will it be enough? Is it that dramatic of a difference?).

No, where the nozzle stops is irrelevant. If it stops halfway back, that means the sector gear has only pulled the tappet plate halfway back and will pull it all the way back to load a BB before shooting.

Seeing the nozzle go all the way back doesn't mean the nozzle is not too long. Dropping a BB into the magwell with the nozzle all the way back will tell you if it's too long. If it isn't too long then gravity alone will be able to pull the BB into the chamber. If its too long then you will have to push it in with a screwdriver, and that is why your mag is having trouble.

Also, when you say it isn't feeding, do you mean it never shoots at all or does it sometimes work fine in semi?

If it is not feeding in semi automatic then your rate of fire is not your issue.

Flarebrass · February 24th, 2014, 17:07

@pestobanana: I agree, I have 2 other rifles, and the SHS nozzles work fine in them as well. One is a G&P and the other a VFC. I will do the manual bb by hand when I have some time and see if it goes in when its all the way back. Assuming that it does go in at that point, what would we be looking at in regards to the issue? It does not feed any bb's at all (full auto or semi) whether it be right side up, upside down or what have you. What does that tell me?

It tells us that most likely the BB is not entering the chamber or your barrel is jammed. I'd rule out the latter because your piston would have stripped from jam induced pre-engagement.

If it does actually go into the chamber freely, I will be extremely baffled. Next steps would be to try shooting the BB after its in the chamber.

Flarebrass · February 25th, 2014, 09:17

@pestobanana: So I had a few minutes last night and tried feeding one bb into the chamber to see if it took. It did not, and every time i shot it moved a little, but never actually went into the chamber. I am starting to think that this has to do with either the tappet plate spring or the nozzle is not in the tappet plate probably. I will check both of those when I get some time, but what other ideas may you have if both the mentioned are ok? Thanks again for your help.

If the nozzle wasn't in the tappet plate the nozzle wouldn't retract. It has nothing to do with the spring because the spring pulls it forward, not backward. Try opening the gearbox and making sure the tappet plate isn't broken and using the original nozzle, it is probably too long.

lurkingknight · February 25th, 2014, 11:37

are you using the lonex tappet plate?

Flarebrass · February 25th, 2014, 11:57

@pestobanana: Yes for sure. Ill double check the nozzle and maybe even throw in the original VFC tappet plate and nozzle and see what kind of difference it makes. Thanks again for the help!

@Lurking: Yes it is the lonex tappet plate that came with the gearbox when I purchased it. I might throw in the VFC one to see if that works any better as well as the original nozzle as suggested by pestobanana above. What are you thinking?

Flarebrass · March 5th, 2014, 10:17

So I removed the stock VFC hop up from the rifle and added a ProWin hop up and the nozzle is still protruding a bit. I shaved it down a bit, but its still in the hop up unit by about 3mm or so. I will take it apart again and see if I was possibly shipped the wrong nozzle or what have you, even try the stock one again. But I have at least eliminated the hop up unit being the issue. Will post again when I have more info. Thanks.

So just an update for anyone who may come across these forums looking for an answer. I have messed around with the gearbox a bit more and also finally found some information hidden on the 7th page of some D-list forum somewhere and the consensus was this: The Lonex tappet plate DOES NOT work with the Siegetek SSG's. It is roughly 2-3mm LONGER than your average tappet plate and is meant to work with lonex gears with a sector clip. From my research, most other tappet plates will work (in my case, it was suggested to get a SHS nylon tappet plate and modify it a bit to fit into the reinforced lonex gearbox). I hope this helps anyone who may have the same issue in the future and knows how to use the search function!

Cheers,

Flarebrass

That depends on what generation of Lonex gearbox that you got - the newest Lonex tappet plates that ship with their complete boxes are back to standard spec.

Flarebrass · March 13th, 2014, 12:40

Hey Stealth!, Very true it seems. I guess it was the longer version (I bought the shell from you as well haha). Do you have any lonex tappet plates of the new sort kicking around that you could send me to try out and see if it works? I bought the SHS from your site, but if I can get one that fits like a glove in there already without modding, I would prefer that. Thanks.

Stealth · March 13th, 2014, 13:00

Good question - we'll look into stocking the Lonex tappet plates in the future.
For now, you will just have to modify the SHS ones that are coming to you. Takes about a minute on the dremel.
