How about $0 bottom metal. Go ADL
Saves weight of course,but IMO never a real good idea for a BG rifle.We like to think that our rifles are never gonna jam, or debris will never get into the magazine to foul things up.Both could happen at inconvenient times and I don't want to pry around with jacknives or disassemble the whole rifle to fix things.
And "no",a hinged floorplate won't open and dump cartridges if properly made.....JMHO; YMMV.
