There are three different version of the trigger but the differences are small  so if you see something that you don't have or don't see something that you have don't worry this will still help you.

Here is what I will be calling the parts (1). Trigger Frame (2).Sear stopper (3).Trigger (4).Main Sear spring (5).Main Sear pin (6).Main Sear(7).Trigger spring (8).Holding Pins x2 (9). Second Sear spring (10).Second Sear (11). Second Sear pin

We start with the second sear 

Put the second sear spring on the second sear pin with the hooked part of the spring in the center of the pin

Then slide the second sear onto the pin and place it into the hooked part of the spring

Now put the second sear pin in the front hole of the trigger

Now put one of the holding pins in the trigger hole just enough so it holds the trigger spring

Then start insert the trigger make sure the trigger spring hooks onto the notched part of the second sear pin 

Now push the holding pin into the back hole on the trigger so it is all the way into the trigger but not sticking out the other side **** This is the hardest part of putting the trigger together****

Now if you have a sear stopper not all Vm's do make sure the second sear spring is up then point the flat side of the sear stopper at the second sear then push the holding pin through the sear stopper but not sticking out the other side

Now take the second sear spring and push it to the back so that goes past the holding pin **** as you do this the second sear will stand up****once past the holding pin push the pin all the way through to the other side of the trigger frame the spring should be under the holding pin

Now put the main sear pin in just enough to hold the main sear spring

now lineup the main sear so the little hook is on the same side as the spring and push the pin all the way through to the other side of the trigger frame

Hook the main sear spring under the main sear

Now push the main sear down at the same time pull the second sear to front so the second sear hooks on top of the main sear

Now put the second holding pin in .You may need to push down on the main sear a little

**** This pin is the pin that fell out on you that made you look at this page hehe ****
