I have made, used, and installed antisiphon tanks for Co2. They are
not as effective as a coiled remote. Remotes keep the tank in the
upright position most of the time so liquid is in the bottom of the
tank plus the gas has about 8 feet of hose to further expand into.
Antisiphon tube must be set up for each specific marker (and re-set if
you change the ASA). It uses a short length of copper tube to change
the point where the valve takes in the CO2 from the bottom of the valve
to a point at the shoulder of the tank. The setup part is to make sure
that the shoulder area where the tube end is is up when the tank is
screwed into the ASA. If it's not, then the setup will act as a siphon
tank until the CO2 level drops below the level of the tube end. Best
setup for an antisiphon tank is as large a tank as possible (diameter
more important than length, but both help). An on off valve will help
keep CO2 out of the marker when it's laid down or otherwise not in use.
Also, antisiphon tanks should only be filled to 1/2 tank volume.
Normal CO2 tank is "full" at 2/3 tank volume (which is why we can get
overfills that kill our burst discs from time to time. An angled ASA
is also much better than a straight one to help use gravity to keep the
liquid out of the system. Player must also exercise discipline to
avoid pointing the marker down as this floods the system with liquid
CO2 (but not true in a remote setup). Finally, antisiphon can't be
used with remote and usually can't be used on different markers.

My personal setup is a Freeflow Shocker with gas through stock (3
points of contact give much more stable aiming platform), Proconnect
III QD, Viper coiled hose (ProTeam), and a 24oz aluminum tank. With
the small diameter coiled hose I can shoot from either hand even with
arms fully extended and I never get problems with CO2 in my reg. Hope
this helps. - Mack
