Super product .... but...odd dimensions - Lothar Walther M1A Match Rifle Barrel

I bought this barrel for my M1A. I have several other rifles with Lothar-Walter barrels and they are excellent. However, I sent my rifle (M1A) and LW barrel to Springfield (the company Springfield) and they could not use this barrel as they do not have a gas cylinder in their inventory that can work with this barrel. My rifle had a Douglas NM barrel from the factory so I thought the dimensions were similar. They are apparently... not so similar.

So if Springfield states they are not able to use this part for a rebarreling effort....my guess is you would have to find a very niche gunsmith to safely rebarrel using this very custom part. This is the 1st LW pre fit barrel I have found that is not “turned” or made to a standardized set of dimensions.
