Making robogen's AR was still a challenge to me, and me using pep for 1 and a half years now, it isnt possible for someone just starting out and never building anything.
The main body was easy as pie, but the grip, the ammo counter, those both took me hours of work because of their tiny little details.
Btw....language of kids has truly changed since I was 12. 5/6 years ago, saying the word "suck" was a word that would make an entire room gawk at you, now people freely say it and dont even know where it originated from.
