Same ammo for both. AA has 10.5" Grendels that cycle existing ammo just fine, and have had them from the start.

Thanks. Being in remote SE AK I have limited options and wondered. I have a fairly good stash of factory 123 SST and a couple of hundred for loading. We're moving south in July. I'll miss AK, but it will be nice to have ready access to ammo and loading components.
