Quentin makes a good point. I bought my first, it was just a plain jane basic AR. Within 3 months I was already putting a second together. And now i'm itching to modify it.
Welcome to the forum though. Just a bit of advice. We don't own assault rifles, the military does. There is no such thing as an assault weapon, it's a politically made up term. And we feed our toys with magazines. Clips are only used by rappers.
