For $7 you can't really complain since it's so cheap but for paying any amount you'd at least expect it to work out of the package.
I had to tinker around with mine for a while and finally wound up filing down the insides of the packing to:
1) Allow a Systema barrel to fit in the first place (The factory dimensions are WAY too small for any barrel to fit out of the packaging)
2) Allow the cushion to be pushed down by the Hop-Up adjuster screw to impart any Hop whatsoever on the BB (Even after filing it down I barely get any Hop affected on the BB)
Aside from the first problem of the packing not fitting a Systema barrel out of the box, they made a mistake in the HopUp rubber in that it's too thin to reach down towards the center of the packing to make the HopUp actually put hop on the BB's.(If that wording makes sense)
When I get some more time I'll swap out the HopUp rubber and see what happens.
On that note, does anyone know of what type/brand of HopUp rubber will even work with the PTW? I've casually looked for them since I've owned a PTW and it seems when your HopUp goes bad you have to buy the entire HopUp packing unit. Is that the only solution?
You saved my $7
First thing came up to my mind when I saw the first link was "damn that silicone packing looks like it came out of MJ's nose"
I guess i have to buy another die-cast systema ring than...
Boy this is my 5th one already

ON THE SAME GUN...
Systema's QC control's gone nuts, one adjuster I bought had a hole pinned in slightly "slanted", making the entire thing useless. I also had a problem with their magazine catch release buttons, as it refused to go in the screw because of bad threading.
