By simply replacing your stock trigger with a Tension trigger and adjusting the travel screws you will shorten your trigger pull by approximently 30-35%. You can remove up to an additional 50% of trigger travel by adding the Bang Switch in place of the stock spool valve, taking your stock trigger pull from over 7mm of travel down to approximately 2mm of travel. This is the most noticeable and cost effective performance difference you can make to your eMek or EMF/MG100. 
(The Bang Switch only works with the stock valves in the gMek, eMek, m170r and EMF/MG100)
 
The Tension trigger is the only FULLY adjustable trigger for your Etha3m, eMek and EMF/MG100. Now you can  fine tune your trigger with an externally adjustable spring TENSION screw. No more disassembling your trigger frame to change the internal spring.
 Not only can you fine tune your spring TENSION but now you can also adjust the amount of movement in the trigger push pin (the pin that the trigger makes contact with), eliminating the wasted up and down movement and creating the shortest possible trigger pull.
