Dragun TES Leaking from front bleed hole

[djeclypse]

I changed every oring on this TES , and taped the relevant threads, but there is a significant leak from the bleed hole under the volumizer. Any suggestions? Is the vertical grip a regulator or a gas thru? Does anyone know where I can find a manual? Thanks!!!

I think I see a couple exposed threads on the volumizer. If that’s the case it’s not screwed in all the way which would cause your problem. Should be a standard bottle o-ring if the one you have on there is making it too tight to fit.

Yeah I don't think that's a bleed hole, it's way too big, looks more like a set screw to make it so the forgrip doesn't twist during use. Leak has to be the o ring on top

Is that teflon tape on the volumizer threads? I'd remove the tape and replace the o-ring.

I don't think that's a bleed port... I think that many guns of this type (JABB w/ volumizer) had a set screw to keep the volumizer from rattling loose. It shouldn't be leaking, regardless - indicating that the volumizer o-ring isn't sealing. After you get the seal worked out, I recommend putting some blue loctite on the threads of the volumizer and omitting the set screw.

So I had another TES and just swapped over the volumizer. Apparently the orings are not really the red ninja bottle sized 015. Not sure about thickness. The thicker 015 I had was too thick. The old green one on my parts TES volumizer holds fine. Thanks for the help!!
