Bob will do you right. The multi caliber system is awesome. I've seen him do a barrel change in under two minutes. That was Beowulf to Grendel, so he didn't have to change bolts. It takes a little longer to swap the bolt for 223, but if you get a whole 223 bolt carrier group, even that only takes a few seconds.
What's neat about it is that you preserve your investment in scope, sights, rail, charging handle, and bipod. You can just get a good list of scope settings for each caliber and you are set.
Bob showed me his rail system when he was working on it. I couldn't quite figure out how it worked for awhile because you tighten down on one screw to loosen the rail.
The trick is in the custom barrel nut. It is about twice as long as the normal nut. The rail fits inside of it and expands out to grip from inside and clamps on the outside.
He has it rigged where it always lines up and is strong enough that he could stand on the rail with the rifle in a vise and it didn't move.
