The critical components to contain a firearm's pressure are the barrel, locking lugs & bolt head. The AR "extension" design makes the locking lugs part of the barrel. There seem to be a lot of advantages to this. An extra-heavy action is longer required. It could be made of lighter/cheaper materials (like aluminum) with perhaps a steel bolt runway. From the Savage switch barrel design, changing bolt heads works fine.
Did the barrel extension originate with the AR design? Was this a new design or had it been done before? Seems like it would be great to have a switch barrel bolt action that would take AR barrels.
Just wondering...
