So, I've decided i want to build my first ar15, and to be completely honest i am a total newbie when it comes to them. I know posts like these are extremely annoying but I am hoping to learn some valuable information. So what do i need to get started? What would you recommend for places to buy from? Would it be cheaper for me to just find a complete rifle? I would rather build it but I have no clue what i should even do to get started. Hes a very good machinist and a die hard gun fanatic, so I was going to have him help me assemble it so that shouldn't be a worry. I am most likely going to be purchasing parts as i can afford them over the next few months. I am looking to be in a $500-700 dollar range if that is realistic to be build a quality rifle. Any advice would be greatly appreciated, and please go easy on me, i know i am a newb.
