Re: 11-87 piston/seal?
The thicker of the two peices slides down first, with the rounded out portion faceing up, then the smaller peice slides down and the rounded edge of it shoud mate up with the first. There will be kind of a flat edge faceing up that actually seals against the rubber o-ring in the gas collar on the barrel after it is all insalled. Also, each peice has a "cut" in it, you want these cuts to be faceing away from each other for a proper seal.
Its kinda hard to explain but i hope this helps, there are also many diagrams on the internet. Trust me, you aint the first person this set up has confused!
