I know this has been talked about like a billions of times but here goes.

So we know there are piston and DI ar15 rifles. They both have a metal rod that pushes the bolt back right?

One of the differences is that most of the gases escapes at the front or the barrel area on a piston rifle and most of the gases goes in the lower rec area on a DI ar.

So why does these companies has to make a proprietary bolt? Couldn't they use the same bolt design? I don't know what that part is called that's on top of the bolt where the rod pushes the bolt back. Please school me on this.
