BG Customs Planet Eclipse ETHA EMEK100/EMF100 Aluminum Sweet Spot Trigger.  Includes the custom-designed Ultralight Trigger Spring for the smoothest possible pull. 

Features:

• CNC machined in the USA
• Hologram milling pattern on the sides
• Post and Pre Travel adjustments
• Ergonomically contoured face for fast-firing
• Shortens trigger pull
• Ultralight Trigger Spring

Installation Notes:

• Use the stock pin for the trigger, which is pushed out from the right side to the left side (due to the knurling diamond pattern) if you are looking at the EMEK from the back.  Do not push reverse.
• Use the lighter spring provided for the best results.
• Do not "over tighten" the smaller 4 screws which hold the plastic retainer cover (on top of the trigger frame) so that they do not strip or break the plastic.
• Trigger "Pre" and "Post" travel screws have been installed with blue Loctite to hold them in place from vibration.  Careful not to over-adjust "pre-travel" (top of trigger screw) otherwise 3-way will not reset (the gun will fire once and not fire again).
• ** Planet Eclipse (Jack) suggests that you need to have about 0.5-1.0mm of trigger travel AFTER the gun shoots for maximum reliability.
