| I'm new here and there is so much great information! Thanks! I'm sure my question has been asked many times, but still looking for an answer. When building from an 80 % lower, does it matter or not matter if it says multi cal? in other words, can I put any upper that is built for an ar15 on any milled out 80 % lower whether it says multi cal or not? What about magazine sizes? I've read you can put a 17HMR on an ar15. How would the magazine work in that case? Thanks |
