Some are made by Lothar-Walther near Atlanta Ga. Actually three piece

barrels..1-inner liner.. 2-barrel shroud... 3-threaded nut/tensioner...

l doubt they are cheaper tho.. Lothar-Walther makes lots of barrels for

many militaries of different countries too. Same 3 piece setup... Look

at an Abrams tank or a Paladin self propelled Howitzer..

Liner/shroud/brake... SAME setup as my 629 Magnum Hunter!!

Abrams and Paladins AIN'T cheap. My Magnum Hunter wasn't either:-(
