All you A5 owners with response triggers will know which o-ring i am talking about. its the small, about 1/8" in diameter black ring that goes around stem coming from the main r/t cylinder. If u have the r/t installed, and u detatch the grip from the upper reciever, the stem is sticking out from the top of the grip where the top of the grip meets the bottom of the upper reciever. If someone can tell me where I could find a new o-ring, i would greatly appreciate it. Thanx.

Here is a pic. Note: the stem coming from the main cylinder, w. the black ring on the end.
