Ya the buffer or bolt won't kill you for sure.
But it might kill a TV or in my case I was going to put it together in the living room.
Once I kinda compressed everything I said to my self.
Hey idiot ,,,,,,
there is a rather large flat screen TV and a 160 gallon aquarium right here with me and this compressed spring and steel parts.
I moved into the dinning room for assembly just to save myself the TV & giant fish from the wrath of mom should I go all butter fingers.
Beltfed the last 4 or 5 rounds I'd have to of just let rip and be all y MAN THIS THING BUMPFIRES NICE! With a smile a cider block couldn't wipe off.
I get it though, no one want's uninvited to the range.
