Are you comfortable enough with the BG308 to be able to disassemble it and remove/modify/replace the safety?
I remember seeing somewhere on the interwebs where someone modified their factory safety buy building it up with epoxy or JB Weld.
OR
Make sure your BG is unloaded; as you are watching TV keep working the safety back and forth... click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack click clack.
It will absolutely drive anyone else in the vicinity insane, but this will break it in and you will get lots of practice flicking the safety off.
