I see Tradeex has 6.5 barrels for 96 Mausers, chambered, threaded etc. I've been reading my refrence material and believe these barrels would fit any small ring Mauser including a 21H Brno (albeit the threads need to be shortened). Has anyone taken this route, just looking for confirmation that it can be done before I purchase a barrel? Thank you for any imput. --- John 303.
