This page holds information on trigger adjustments, sub-divided according to the type of Shocker/Nerve frame in use. Most triggers offer ample adjustability however some aftermarket developers have redesigned the trigger and/or frame, which sometimes results in removing some of the available adjustments.

Smart Parts trigger adjustments:
This applies to stock Shocker SFT and Nerve frames, along with any triggers made by Smart Parts (which includes most private label triggers and frames). Smart Parts OEM triggers allow you to adjust the following:
Pre-travel: The length of the trigger's forward swing. On most triggers, adjust by screwing inward for a shorter pull.
Post-travel: The length of the trigger's rear (pull) swing. On most triggers, adjust by screwing inward for a shorter pull.
Firing point: The point during the trigger's swing where the microswitch is actuated to fire the marker. On most triggers, adjust by screwing inward for a shorter firing point.
Magnetic tension: The weight for the trigger pull. On Shocker SFT frames made by Smart Parts, adjust by screwing inward for greater pull weight.

Smart Parts trigger set screws are 4-48 thread which use a very small 0.050" allen key to adjust. You must take care not to strip the set screws, becuase they can be extremely difficult to remove if stripped (sometimes they cannot be removed at all). Most private label Shocker SFTs also use triggers made by Smart Parts, so they are adjusted in the same manner.

Smart Parts frame magnet screw adjustment:
Magnetic tension adjustments are made by changing the position of the magnetic screw located behind the trigger, in front of the lower circuit board. This screw has a small magnet in the center which repels against a corresponding magnet located in the trigger itself. In order to access this adjustment, you must remove the Shocker's lower board by removing the two 5/64" "board pins" holding it in place. Once the board is out of the way, use a 1/8" allen wrench to adjust the magnetic set screw in or out.

New Designs SFT trigger adjustments:
NDZ triggers use the same adjustment system as the stock SFT triggers. The only main difference is the screws are larger (6-32 thread) which use a larger 1/16" allen key to adjust.
When purchased new-in-box, NDZ triggers come with a separate magnet which can be used to repel the stock frame magnets. The magnet is held inside a hollow set screw within the trigger (commonly called the "magnet cage screw") which can also be adjusted instead of taking the frame apart to access the frame magnet screw. The magnet must be placed within the hollow cage screw in such a way that its magnetic pole repels against the frame.
If you purchase an NDZ trigger secondhand/used, you might not receive the magnet. If this is the case then you can probably steal a spring from a ball-point pen and use it to push the trigger forward.

Hybrid Traitor Shocker SFT frame adjustments:
Hybrid frames are one of the only private label Shocker SFT frames that were not made by Smart Parts; instead they were made by Hybrid Technologies themselves. The trigger system is very different; Hybrid triggers are not compatible with any other Shocker frame (nor are standard Shocker triggers compatible with a Hybrid frame).

The magnet system is redesigned by placing a large disk-shaped magnet above the trigger, which attracts a magnetic set screw located in the top of the trigger itself. All Hybrid SFT trigger set screws are adjusted using a 1/16" allen key.

CCM Shocker frame adjustments:
CCM frames use their own special trigger which has a "shoe" covering the trigger adjustments. To access the adjustment screws, the trigger shie must be removed using a 0.050 allen key. The trigger adjustments are explained in the diagrams below. The only difference is the firing point pivot adjustment, which allows you to change the angle of the firing point set screw. The microswitch firing point can also be adjusted independantly from the pivot adjustment. The pivoting action allows these triggers to be used with either a flipped or non-flipped switch with ease.

Logic VS and USF frame adjustments:
Logic frames were made to utilize typical Shocker SFT triggers, so most of the adjustments are identical. However, Logic frames use a redesigned magnet system by placing a new magnetic screw above the trigger, which attracts the trigger's original pre-travel set screw, making it into the magnetic adjustment instead.

Pre-travel adjustment: The magnet screw in the top of the frame is used to adjust the trigger pull's pre-travel length. This adjustment is carried out using a 5/32" allen key, and can only be adjusted while the frame is separated from the marker body.
Magnetic return: The magnet inside the frame attracts the trigger's pre-travel set screw. To adjust the strength of the magnet return, adjust the trigger's pre-travel screw to your liking. The closer it is to the magnet, the heavier the pull will be (and vice-versa).

Nummech Pie frame adjustments:
Note: Detailed information on Pie frame compatibility with Shocker/Nerve components can be found here: Pie frame compatibiltiy

Nummech's Shocker Pie frame was made to adapt most standard Shocker triggers, but the useability and adjustments depend on the specific trigger being used. Nummech recommends using a Shocker SFT-style trigger rather than an NDZ-style trigger, for greater adjustment.
If using a Shocker SFT trigger, you will likely need to modify the Pie frame's trigger stop component (located behind the trigger).
If using a Shocker NXT trigger, you will likely not need to modify the frame, however the trigger set screw assignments are different, and you will probably no longer have a trigger pre-travel adjustment.

Pie frames don't use a trigger magnet, instead they use a spring located behind the trigger. The trigger spring has no mechanical adjustment so the only way to alter the tension is to stretch it or cut it. If you need a replacment spring, you can try stealing one from a ball-point pen or similar.
