AR15 Trigger Slave Pin

I know this seems dumb and way too simple of a design.  However.  If you have ever struggled to get an ar15 trigger and disconnector to lineup properly when putting the trigger pin in, trust me it helps soooo much.  Put this pin in to hold the disconnector perfectly in place in the trigger, then put the assembly into the lower and push the trigger pin through.  The slave pin holds it all together and lined up until the trigger pin pushes the slave pin out of the way and it all effortlessly lines up for the pin to easily seat.  Maybe you are all better at this than me, but in the slim chance you have the same issue, just try it once.
