That's probably the worst thing you could do to that rifle if it were possible. Adams Arms has external piston uppers for the GII, but I would never do it.

Why do you say that? Will the weight of the moving parts degrade accuracy? The only reason I posted this is because I would like to keep the chamber as clean as possible.
