All Shocker Sports came with a bottomline screw-in version of the Max-Flo regulator. This is the older "manifold" style regulator which includes an integrated ASA (called the reg manifold) which attaches to the regulator itself, located under the manifold. There were two main versions of this screw-in Max-Flo reg, pictured here:
Above is the 1998-1999 version in the first pic, then the 2000-2002 version in the second. This was always the stock reg setup, however you could opt for another reg position if you wish (below). The older screw-in Max-Flos could be mounted to any standard drop-forward as long as it fit. However, the newer version Max-Flo screw-ins used their own mounting dovetail which required the use of the special dovetail mount. Note that this is different from the "dovetail rails" that makrers use today.
Vertical Max-Flo:
An "upgraded" regulator setup involved removing the screw-in "manifold" ASA and relocating the regulator to the front of the gun, so it would function as a foregrip. This was accomplished by installing a vertical Max-Flo mount which would hold the Max-Flo reg in the vertical position and allow you to attach the hoses as required.
There were two main versions of the vertical Max-Flo mount, an SP version and an Eclipse version. The SP version positioned the reg further out the front of the gun, and is pictured directly below. The Eclipse version positioned the reg directly in front of the trigger guard, and is on the second line of pictures below. The Eclipse style vertical mount was mimicked by many other companies and custom shops.
Both versions of the vertical mount will hold the reg tighty in position, and require the reg's input/output to be piped in and out of the reg separately.
The Shocker Sport was designed before the "standard" vertical regulators became popular (as in, the vertical regulators that use vertical ASA threads). As a result there aren't any drop-in vertical ASAs for this gun. You can rig one up using a universal ASA mount, but this is a custom mod so it's much less common.
Horizontal Max-Flo: aka. under the barrel Max-Flo
There is one other possible mounting position for the reg, it's neither bottomline nor vertical. It involves mounting the regulator horizontally in front of the gun, directly under the barrel. There are many ways to mount this, some of which are shown here.
This version below is my favorite setup; it uses a male/female quick-disconnect fitting to mount the reg in position, allowing it to be easily removed when necessary. The male QD fitting screws into the front of the gun, and the female QD fitting attaches to the 1/8" NPT elbow using a 1/8" union coupling.
If you don't want to bother with the quick-disconnect setup, you can simply mount the regulator to the marker using any 1/8" NPT fittings you can find. The disadvantage is that the regulator is fixed in position and often can't be removed unless you're using a removeable fitting. Below are some examples:
Other Regulator Setups:
If you don't have access to one of these manifold screw-in Max-Flo regulators, or have an incomplete regulator, you can still rig up a functional reg setup that will be able to operate the marker. The only requirement is that the reg drop the tank pressure to 150-200 psi before it enters the marker.
Pictured below is a marker using a Palmers Stabalizer regulator, mounted to the bottomline.
Below is an example of another way to mount the same Max-Flo reg, except without using the manifold screw-in ASA section.
Max-Flo Port Assignments:
One of the advantages of this older style Max-Flo reg is that it's very versitile in mounting methods (as described in the above paragraphs). If you're unsure how to attach the hoses, here are their assignments. The regulator has one input port and four output ports. The four outputs are all located around the same position on the reg (one output port points in each of four directions, the same length on the reg body). These are used for the output hose, a PRV (aka. bleed valve), operating pressure gauge, and the last output port is pluged off. The lonely air port located slightly behind the four outputs is the input.
Air Source:
With this marker you can use virtually any HPA tank. However, for compatibility reasons, we suggest you purchase an HP-output HPA tank (instead of an LP output HPA tank) since it will work on virtually any other marker out there.
If using a CO2 tank, you will need to use a correctly-installed anti-siphon tube in the tank. This will prevent the marker from drawing liquid CO2 up into the regulator (which is not desired). If you're using a vertical Max-Flo (or one of the under-the-barrel regulators pictured above) then you won't need the anti-siphon tank. Anti-siphon is only really required for bottomline regulators.
