Can someone please recommend the tools I will need in order to complete my lower. I have a Spikes stripped lower and a complete lower parts kit (MOE). I've watched a few reviews and didn't gather much info besides "I like this hammer the best because it won't leave marks' - ok so what kind of hammer is it! or here are my punches i use they work really well' - ok are the brass? what are they? so if anyone has good info or a list of tools that I need please help me out.
