The Cdn. demils were torched through the barrel a couple of places, including through the gas block. The receivers were also cut, usually down through the ejection port, with the action closed. Cut went through the receiver, the bolt, and slide. From the left side, the rifle looked OK, right side was bad. The ones I saw had been in excellent condition. Hard to cosmetically repair the receiver. Help yourself to the "happy switch" line. A 1918 BAR was safe, semi, auto. The A2 was safe, slow auto, fast auto. Slow was about 350 rpm, fast 600 or so. These rates would be dependant on ammunition, fouling, gas setting, etc.
