Looks nice, What is the inner diameter of that KM head barrel? And what is the legnth? I was looking into one of these but didnt know if it was worth picking up. THere are two KM head barrels, One that is teflon coated and one that is stainless.
Also, with the PDI HD piston, You're losing alot of compression. If you get the raven cylinder set, the piston will fit alot more snug into the cylinder.
