12 for $5.  Would work well for a smaller tank.  2.45" diameter, 3/8" bore.

[TANKS] Re: Dangerous Power E1

[TyngTech]

The E1 is a nice marker.  If you wanted to go more compact you can lop off 
an inch from the back end quite easily.  Everything to the right of the red 
line is not needed for marker operation.



As Doug stated, the marker runs off of 150 to 200 psi pressure.  Never run 
straight CO2 to the marker.  The velocity is adjusted by adjusting the 
regulator.
