I took my 1944 DOU to the range last night to see if it would fire since the sell on GB does not test fire. Good news is that it fired. The bad news is that the upper handguard was loose and apparently so was the rear barrel band. Fired one shot and the band was moved out of position and the handguard fell off. Does anyone have any suggestions on how to fix this? Was thinking just a little gorilla glue but wanted to turn to you guys, the experts, for more sound advice. I don't plan on shooting this rifle as much since it is more collectible than my RC BCD. Thanks for the help.
