Definitely the AUG for me.... I wanted one ever since it made an appearance in Die Hard. Ergonomics are great, 42 round magazine as standard, ridiculously easy barrel changes and field strips, and one of the few guns that I can do a "thorough cleaning" on in less than 10 minutes (and I'm pretty OCD). However, the trigger from the factory was 12 lbs. I can shoot it well, but the finger workout takes serious effort and concentration. After some aftermarket parts and some minor polishing, I got it down to 9 lbs. As much as I want to love this rifle, the trigger keeps it locked up in storage.
