WETTI/AWSS - M4/SCAR/HK416 - Technical Summary Thread

[Eeyore]

I'm trying to build a second upper for my WE M4. I have an inner barrel and the brass tube and some of the hop up parts but I can't figure out what part 116 is. Anyoone know? I don't see it for sale on airsoftbuddy.com either.

Thanks

Tom, part #116 on the WE M4/M16 is a spring that is between the hop up adjuster & spacer and the nut that holds that spring down.

Thanks. Any idea where to acquire said spring?

How the hell did that happen?

[MrEvolution]

Absolutely NO IDEA.

Took the gun out today first time since novemberish.
I would fire BBs (BB Bastard .20 and TSD .25) and they were jamming in the barrel right at the hopup/entrance. Pulled out the bolt and noticed it was FUBAR.
Took the NPAS off to see if I could wind the brass part back up to the steel, took it apart and the inside came out and looked like that.

Maybe I got a lemon, maybe it was installed improperly to begin with. Honestly dont know

Sam,

Since your screw/plate portion of your NPAS valve is OK...I can just reuse a stock valve and make you an NPAS. If you're shipping stuff to me, just be sure to include all the busted bits as well as the rest of the stuff.

I've got all the trigger mechs, nozzles, rods, spacers, blah, blah, blah that you'd ever need.

Let me know when you've shipped it. Nows a good time to do any other things you want to it, since I'll tear it down completely and give it a once over as I reassemble it.

Sorry if this has already been posted, but has anyone had an issue of all the gas spewing from the ejection port or from the inner barrel at the tip of the gun? I checked my floating valve (stock we M4) and the fire pin delay (part 66) and they seem to be fine..It fires the first shot then all the gas comes spewing out..

EDIT: Im not sure if this has anything to do with it, but sometimes the nozzle is a bit sticky to the hop up.. When i manually pull the bolt back, i can feel the tip of the nozzle having some resistance with the hop up. Just started recently.
