quick question; I recently got a WE GBBR used from a buddy (it's a lower clear M4 version.)
I just got in the mail a RA Tech NPAS kit (version 2 for WE M4), stinger hop up kit for we M4 and fire pin base w/ valve locker (as well as a TSC charging handle and a thread adapter.)
I also picked up an
RA tech hop-up rubber (says for open bolt system/GBBR, but didn't see any rubbers for close bolt - I think mine's a closed bolt) and an
RA tech inner barrel.
However, the barrel I ordered is set-up differently than the rubbers. Now, normally I would just tear down the gun to install the Stinger kit to see whether I have the right hop-up, or the right barrel and order the other. However, my upcoming week is extremely busy and I don't think I'll have the time for that, but I'd like to order whatever I need to make it work so it's here for when I do have time.
Now I'm sorry if this has been answered here or elsewhere (or if this question doesn't belong here), but I've seen nothing mentioned, but if it is a new rubber I need, where would I be able to get one for that barrel? I've look all over, ehobby, redwolf etc but haven't seen anything different from what I've posted.
Edit:
Looking more closely at my stinger kit, I noticed a thin rubber ring that looks like it'd fit that barrel, is
that my hop-up rubber? (before I had just assumed at a quick glance it was a spacer or a rubber washer of some sort) If so, suddenly so many of the mods I've heard mentioned on the rubbers make sense...
