Lucky

Thanks for the info. Building another upper and was just wondering. Now im wondering how straight my first build was. Oh well it shoots lights out so maybe i got Lucky again. My buddy who is a good smith chambered the barrel and put it all together for me so he probably did the work. Like i said it shoots good. Ill check out Rainier Arms& see if they offer a 10 receiver too. Thanks again

First time to ask a question on this site, tried to search this topic unsuccessfully. Hope i didn't miss it somehow, if so, kindly direct me to the thread. Anyway , billet vs forged upper receivers? whats the advantage of one over the other?
