Trigger not springing forward
 

Ok, well my trigger does spring forward when I am not firing, but when I shoot the gun in semi auto it doesnt spring forward. Could someone send me a pic of exactly what my trigger area is supposed to look like. By the way I have a TM MP5. If you have any ideas to why this is happening please tell, however, I think I must have installed the trigger spring incorrectly. A pic of the trigger unit would really be appreciated!

It's very easy to figure out. There is a 90deg hook on the spring, that goes into the little hole on the rear of the trigger. The other end of the spring points forward and stays inside the mechbox. I had this happen once to my MP5, the hook wasn't placed inside the trigger. Easy fix.
