The only purpose of the that part is to hold the buffer in the position required for you to open or close the upper. I understand and appreciate you concern. Ultimately it is your gun and decision.
If I could get the part before the class I would, but I would not let a buffer retainer keep me from attending a class. Again, your gun, your decision.

Indeed. It helps that 1) the part's on its way 2nd day shipping and 2) it's one of Grant's free classes so it's not like I'd be out a few hundred bucks if I had to take a pass this weekend.
It's the superstition in me that is wary of calling down the wrath of the AR gods :).
