Rifles with swappable barrels and bolts? There isn’t much benefit over having two separate guns. They typically cost a LOT. If you have to swap between .308 and .338, or vice versa you’ll have to re-zero each time; plus you’ll need different magazines.  It makes a bit more sense for people who are limited in the amount of guns they’re allowed to own. Sauer and Blaser did it with hunting rifles in Germany, where your hunting certificate limits how many guns you can own. Sako also did it with rimfire cartridges.

On the tactical/le/military side, it popped up when military contracts started requesting it (I suppose to save $ on ammo, and having a single nearly identical setup for training vs. combat).  On something like an AR-15, it literally just means swapping the whole upper receiver with a different chambering.

Or did you mean something else?

I had seen a multi cal option on rdsc for the MRA. I was only curios mostly why I made this post and this goes for all firearms not just the MRA. Thanks for the reply !

That is refering the a receiver that can be used to Build several into multiple caliber options. Not necessarily swappable without work and tools (or a replacement upper) or able to shoot different calibers at the same time.

That’s basically how many AR lower receivers, without specific chambering markings, would be listed on a registration certificate; until you built a full gun, and amended your registration certificate.
