Then just use the trigger mech...

LMAO...

This is the best advice. If your friends gun is useless, just take his trigger mech and use that instead.

This will give you some time to save up for a zero trigger.

I am pretty sure that Inthetallgrass is right, I had the same problem and freaked out. It goes into the bolt handle, not the trigger mech.

That pin looks a little odd compared to the one I found in my rifle (on the bolt handle).

However, I never found a piece like that in my trigger mech either. I would take apart the trigger box and see if anything is out of place. Even if that piece goes to the bolt handle, you still have a problem with the rifle.
