OK I want to build/put together my own AR15. My question is can you use a single Lower unit for multiple caliber uppers? I know it sounds like a dumb question but I want a 223 and also a 7.63x39 due to the lesser coast of ammo. Thanks, Lee |

The only time you need a different lower is when you want to go to .308 lengthed cartridges. Other than that, yup g2g. Setting up for a 9mm upper does require a couple different parts for the lower, but you still use the same type lower as the .223/5.56 etc. class cartridges. Brian |
Here's some reading More reading . Even if you don't plan on building, knowing how the AR goes together is good info. Welcome to the dark side! |
