I am looking at putting together an assault / tactical rifle. I am very new to this, and would like any info on where to look, websites, books, etc. I assume I can find some stuff on Youtube and the internet, but I want some real persons input, not just some info from a website trying to sell stuff. I don't know what is good and what is bad. I am not looking for something very expensive. I want something fun to shoot, and that will hold up with proper cleaning and maintenance. I was also thinking about a 9mm carbine or something. Let me know what you all think. Thanks.
