If you mean by "binary trigger" a two stage trigger - yes. All my AR's have either the Compass Lake Engineering 2 stage or it's equivalent Bushmaster (CLE ripoff) 2 stage trigger.
Rob - your picture reminds me of a post on a similar thread a couple years ago. The guy had multiple implements on his tractor that allowed him to pick up and transport either ten or twelve round bales. Very unusual and top heavy when it was fully loaded.
