A good friends HBAR was damaged in a house fire, all but the lower had to be replaced,; long and short, it was sent to a smith for complete rebuild. The range test was quite exciting as it went into "burst" mode.
Nice at a private range, but wanted to go "full" auto as it heated up. ......
It went back to the smith to "cool" the thing off and keep it
civilian.
As KPR posted,...our nanny state makes us go through hoops for rifles with a "happy switch", but if we buy one that does it on its own, .....time to send it back.
