May be a stupid question, but I will ask anyway.  How many possible calibers can an AR 15 stripped lower be built.  I guess it is limited by the OAL of a particular cartridge, correct?  Is there a "magic number" that is the limit?  I'm pondering whether or not to purchase a stripped lower or two for the future.  I already have ARs in .22LR, .223, 300blk, and .308.  I am just wondering what are other possibilities etc.  Thanks for your help.
L.P.

Can't you also do the 6.8 Grendel in an AR build?

pretty much anything that will fit in the magwell and with specialized uppers a lot of things that won't.



If you step up to a 308 size that gives even more options.

No 9mm AR?  It's one of my favorite range toys.

I believe Grizzly made a single shot, bolt action .50 BMG with an AR lower.

I believe the .50 Beowolf is on the list as well.

another good reason to read the tacked threads at the top of the forums, notice it says Read_First  it is actually what you can build an upper for.  items like 50bmg will obviously not work in a lower.
scroll down to number 15  Hope it helps













lol, knows calguns better than arf
