Lothar Walther sent me a barrel to test and review. I received the barrel yesterday. The machining is impressive and the rifling is clean inside. My gas cylinder and flash suppressor fit with good taps from my gunsmith hammer. Not too loose and not too tight. Just right! I found it interesting that forward of the front band, it holds a GI profile. The barrel is not stainless and is in the white. I'll need to send it off to be park'd. I've got a guy lined up for it. It hand timed at 55˚ on a LRB rear lugged receiver. It will go in a JAE first, followed by a McMillan, followed by a Fajen heavy walnut. There are no markings at all on the barrel and I found it interesting that there is only one wrench flat by the chamber. It does not come with an operating rod guide. I ordered one from Kreiger today. It is made from LW-19 sulphurless steel and is "in the white" and will need to be phosphated, painted or DLC'd. I posted a quick video with a new Teslong borescope...
