Never done this before so any tips and advice is more than welcome... looking for advice on building an AR, starting with the lower receiver I’m assuming the first step would be getting a lower parts kit? ...and with that, the first step is to install, carefully, the trigger guard. other than that assumption (correct me if I'm wrong) I know nothing... So what Im asking is in 3 parts... 1) any advice on which lower parts kits to buy? In another thread here 3MTA3 tipped me off to the ALG ACT trigger and despite what little I've read about triggers I really like the idea of starting out with a quality trigger. Its available from them in a parts kit. I don’t mind spending a little extra money as I’m not necessarily looking into a budget build as for now I have no time frame to complete the build this is a just for fun project.... 2) advice on tools needed? ...is there a compete took kit I can buy to end all AR tool buying or should I buy better quality tools individually as I go specific to the step Im doing? 3) any tips advice on actually assembling? For example I read the trigger guard is something you don’t want to screw up even though it appears a simple step! I have not purchased anything yet but getting close and just want to learn more before I dive in.
