Spyder non threaded volumizer?

Hmmm, there's a few of those NW kits floating on ebay. Probably easier to source, might go that route.

Just look carefully. NW also sold a rear cocking adapter that was just an extension that moved with the bolt.

Well it turns out the azodin zero kit does not quite fit. The mounting divot is just slightly too far forward. So I’ll probably run it without.

Now one I just have to convince the store owner to put the purple one up in the museum so I can take the blue/black one...

or leave the stock cap, thread a hole in the front of it for a small barb fitting and run a small line to a little expansion tank that mounts to the side of the bottom tube. like a 12g co2 tank.

I like this idea. Personally, I would tap the front of the plug for 1/8", and put an (albeit narrow) expansion chamber horizontally (assuming it would clear the barrel, of course). If looks weren't important, a person could just use a threaded piece of basic brass tubing.

OP be advised, the threads on that line are most likely metric, not 1/8".
