| I understand that the 5.56mm/300 BLK JAKL uppers can be put on any normal milspec AR15 lower, but what about the 9mm JAKL upper? I'm not clear if you have to use the AR-V mag JAKL lower with it or not. Will a 9mm JAKL upper work on a normal AR15 lower used with something like these CMMG magazines or these Mean Arms Endomags? What about a DDLES lower that uses Colt 9mm SMG magazines? |
| Ar-v lower only. The ARV lower and upper (which the jakl design uses) are proprietary. |
