The FTP has a rail extending out from the action. Attached to the rail is the cylinder and barrel support (sort of like a eight)
I had asked about glass bedding the action on pcps on another forum. I was told that it didn't make a difference. I think you're on the right track. What you described sounds like free floating the barrel on rimfire and centerfire rifles.
I'll do this to my S510 and Regal.
Tanks again for your advice.
