The vertical adapter is the ASA-threaded piece that attaches to the underside of the body, into which a vertical regulator or standard gas-thru grip is screwed.
The vertical adapter is held onto the body using a 1/4-28 x 1/2" screw, with a lock washer around the head. While the regulator is removed from the adapter, use a 3/16" allen wrench to remove this screw for disassembly. Located between the adapter and body is a 14/70 o-ring, which seals the air pressure passing through the ports in the adapter. Shocker and Nerve vertical adapters are the same, so one can be interchanged with the other without any problems.
Body Porting & Vertical Adapter Pin:
The underside of the body is ported for air input above the vertical adapter. Located around the screw hole are two holes, one of which is used for air input, while the othr is used to hold the vertical adapter pin. This pin is used to hold the vertical adapter in position and prevent it from twisting around when you remove the regulator.
If the regulator is overtightened into the adapter and the pin is missing, the adapter will most likely grind on the body and swivel around instead of allowing the regulator to unscrew. Because of this, it is strongly suggested that you use the vertical adapter pin.
The top of the vertical adapter is ported with seven smaller holes. The middle hole is made to mount the vertical adapter pin, however if you wish for the reg to face a different direction when installed, you can move the pin to a different hole. The pin location in the top of the adapter doesn't matter, but you must still make sure the pin doesn't block the air input port on the body (as discussed above)
Please note that the NDZ vertical adapters don't require the use of the pin because they are specially fit to the underside of the body, and cannot swivel in any direction.
Aftermarket Adapters:
There are a few varieties of adapters available for purchase, all of which are listed here:
· Smart Parts vertical adapter with gauge port: Shaped somewhat like the Nerve vertical adapters and has an output for a gauge. Comes stock as of 2005 on most Shockers. This adapter is seen in the above pic (of the red and orange Shocker...the orange one has it).
· New Designz vertical adapter: Comes in two versions, straight or 15º angled. Both versions will accept a gauge for the operating pressure. Gauge is not included with it, however can be purchased along with it if needed (a gasline plug comes with the adapter if you do not plan on using a gauge). NDZ adapters cost a little over $30 from most NDZ retailers. Please note that the NDZ vertical adapters will not fit on some private label Shockers, such as the Strange or Dark (these Shockers have a wider underside in the front, which does not fit the NDZ adapters).
· Hybrid 10º angled vertical adapter: Comes on the Hybrid Shocker; available in black only. Costs $46 from bradyspaintball.com
· Additional private label Shockers may come with their own vertical adapter however no others are available for purchase separately.
Overview:
· The vertical adapter screws into the body and holds the vertical regulator. The Shocker SFT and Nerve share the same style adapters.
· An o-ring (stock 14/70) seals the connection between the adapter and the body. Aftermarket adapters may use different ones.
· The vertical adapter requires the use of a pin to prevent it from swiveling around on its own.
· Aftermarket adapters, in both straight and angled versions, are available.
