Hi, I am curious if anyone has any experience with the $83.99 short chambered Mauser barrels from Brownells? I have used the Adams& Bennet barrels from Midway with good results, but The 21" F14 contour is a little short, and the 24" F34 is kind of heavy. what kind of contour do the Brownells barrels have? any idea who makes them? I heard the Adams& bennet are made by E.R.Shaw, but I can't confirm that. Any other good sources for inexpensive decent barrels?
