Adams Arms Piston Kit Receiver bushing Dimensions?

[Gas Can]

Dose anyone happen to have an uninstalled Adams Arms piston kit that could mic the dimensions of the upper receiver bushing? ie the little bushing you press into the upper receiver gas tube hole, that the drive rod goes through.

I only need the OD and length, I can get the ID off the drive rod.

I would contact Adam Arms.

I just installed mine in my upper last weekend. Wish I could help.
