Thanks Doug. I am familiar with the disassemble of the gas piston on the Garand and have removed it for cleaning a few times. As far a the Carbine is concerned, I guess I will just use conventional bore cleaner and a bronze brush. The strange part is that the instructions that came with the Carbine say to clean it upside down to avoid getting cleaning fluid into the hole in the barrel, but when you are done cleaning it, turn the rifle right side up and pass an oily patch through it so a bit of oil gets into it. I would think a combination of oil & carbon would gunk up the piston, but that is what they say to do.

I am going to check out the Brownell's web site in a minute as per your suggestion. Thank you.

Regards,
