From here you put the hiperfire springs back (can be found online).GT Single-Line Replacement Spool (Part #21560040) (GT Models) (Discontinued):ġ. I use a punch to help wiggle through the hole once both disconnectors are on the pin: Press down on the shelf of the echo disconnector while pushing up on the tail end and press pin through echo disconnector hole (same as the semi disconnector above): Make sure the spring stays in the notch of the trigger pack: Slide the hole in the bottom of the echo disconnector over the spring. Place the echo disconnector spring into the spring notch: I use a punch small enough to fit in the echo disconnector spring so that it will slide off the punch. You want it to go far enough to hold the semi disconnector while also leaving a gap for the echo disconnector: Then take the other pin and insert from the same side as the semi disconnector, using the same technique above. Then I press down on the trigger pack to push the pin through: An easy way I found was place the pin on the bench (or a piece of wood), partially through the hole, while pressing down on the disconnector shelf with a punch, and lifting up on the tail end of the trigger (under the back-up disconnector). Take one of the large pins and push through the hole from the opposite side of the semi disconnector. Slide the trigger back into the frame (you will have to press down on the disconnector for this): Put the semi disconnector spring into the right-side hole (looking face on) and place the semi disconnector over the spring: It should pop into place without too much force: Replace the spring and press the bottom of the spring with a small punch, while pulling the disconnector back. Press forward on the back-up disconnector and the spring will pop out of place (great because removing the pin that the c-clip is holding is a PITA):
Remove the trigger section from the trigger pack frame:īelow is the back-up disconnector spring that was replaced On my newer echo both springs were the same:
I kept the stiffer spring under the echo disconnector, and the lighter spring under the semi disconnector. For this trigger, the factory disconnector springs were different. Tap out the large pin that holds the disconnectors with a punch and hammer (face on view, the semi disconnector, with the tail, will be on the right. Take a close look at how the disconnectors sit in the trigger pack: This should push out with a little force or light hammer taps and a punch: Next I removed the hammer and hammer spring. Remove the hiperfire springs by placing your hand over the hammer pushing up on the tail end of the trigger pack: The spring I replaced was the under the back up disconnector for this one, the semi & echo disconnectors have factory springs. This is the step by step process on how I change out the disconnector springs for the echo trigger. Only modification is changing the back up disconnector spring. The semi-mode trigger pull is right around 3lbs.Įcho mode initial pull is roughly 3.5lbs and the echo reset is a hair over 4.5lbs.
