Mean that it isn't listed for a specific caliber. Depends on the barrel in the upper what caliber it will shoot.

Quoted:
My Lower is stamped: Caliber: Multi Does this mean it is set up for either 5.56 or .223? Or, does this mean something else? Thanks in advance!! The lower will not matter, you need a barrel stamped for 5.56 in order to "safely" fire either round. If it is stamped .223 DO NOT FIRE 5.56. |

If you have only a lower receiver the ''multi'' caliber can be used with any caliber upper that works with the AR15 receiver. AR15 lowers are not made specific to any caliber. There are 9mm and .308 type receivers that differ from the AR15 receivers though. If you have a complete rifle, you need to figure out what the barrel is chambered in. 5.56 and .223 can both be shot through an AR chambered for 5.56. You need to 'make sure' what the barrel is chambered in before shooting anything through it. As mentioned, there are several different calibers that the upper may be chambered in although 5.56 is by far the most common. The ''multi'' doesn't tell you anything.
