Bottomline Accessories:
Base model Shockers come with a screw-in on/off tank adapter (Smartvalve) along with the Smart Parts Angle drop forward rail.
Smartvalve ASA:
The Smartvalve is an on/off ASA adapter for your CO2 or screw-in HPA tank. The built-in shutoff will function with little to no maintenance over a very long period of time. The NXT frame uses a built-in dovetail mount, however you can also use an y standard dropforward or dropback, using a dovetail rail mount.
The bottomline Smartvalve is designed to be used in conjunction with your screw-in tank at all times. This means, ideally, you should screw your HPA tank onto the valve while empty, then fill the tank while it's mounted to the gun. You can easily remove the tank while it's empty, if you need ot swap to a different gun.
The on and off positions aren't marked. The exact position depends on which side of the housing that the valve knob is accessible on. The old-style Smartvalve has the knob on the right; new-style (current) Smartvalve has the knob on the left.
You may wish to mark one of the positions on your valve, if you have trouble remembering.
When filling the tank while mounted to the Smartvalve, always be sure the valve is in the off position.
Smartvalve disassembly can be found under the Regulator Maintenance section (refer to the Related Links). O-ring diagrams can be found there as well.
Vertical Regulator:
Incoming pressure from the air source leads into the vertical Max-Flo reg, stock on all Shockers.
The vertical reg is used to adjust the velocity of the shots. Adjustment of the reg is accomplished by using the provided 5/16" open-face wrench to screw the large adjustment nut on the bottom in or out.
The threads on the NXT vertical reg are reverse-threaded, so screwing the endcap in will increase the pressure, whereas screwing the endcap out will decrease it.
Air Source:
All SP markers will easily accept CO2 or HPA without any special modifications.
When using CO2, an anti-siphon tube must be installed and functional. This can be purchased from most proshops, or from many online retailers (tanks with anti-siphon tubes installed can be bought new as well). Without an anti-siphon tube, the regulator will draw liquid CO2 into the marker, which will damage or destroy required seals within the marker and reg.
When using a preset HPA tank, I suggest you use an HP-output preset. Virtually all markers are designed to use HP output tanks so to maintain compatability with other markers that require HP tanks, I suggest you just use an HP. An LP tank won't perform any better.
When using an adjustable tank system, HP input to the vertical reg is required. Please refer to the Pressure & Dwell Setting page in the Related Links below.
Macroline:
All SP markers come with standard 1/4" macroline and Norgen macroline fittings installed. These are upwards or downwardly compatible with other macroline components, as long as the sizing is correct. Microline isn't suggested for use on these markers. Stainless braided hose can be used, though disassembly will be more difficult.
Overview:
· Shockers come with a dovetail Smartvalve ASA installed.
· Velocity adjusting is carried out through the vertical regulator, screw in for more pressure and out for less.
· CO2 or HPA can be used with the Shocker. If CO2 is to be used, the tank must have a functional anti-siphon system installed.
