I just purchased my first stripped lower and plan on making an AR 15. I plan on making a 5.56 with a 16 inch barrel. I was curious who you guys buy from and what parts you recommend. With this being my first gun, I want to go pretty basic and would like to keep the cost down. If this is something I decide that I enjoy I will build the pricier gun later on. So I am looking for affordable yet quality parts. Thanks
