Looks kind of crazy but should be fun. I tore my recently modded 2240 apart just to see what was inside. I built it 15+ years ago and have been modding it ever since. I found a really old valve that I modified and never touched again after all these years and tens of thousands of shots. So since it still werqs and is not leaking I just cleaned it up and put it back in. Old trigger with one of Steve's early steel adjustable sears on it too. We have to do something while we wait out the viral war. Have fun with your new build.
