Sorry I'm late to the thread, but I manage the AR-15 Parts Weights Database, or PWD. I need to do an update, but it's the best resource for part weights on the internet. Thousands and thousands of parts. If you want to know how to build light, this is where you start. Sub-3 lb ARs are entirely possible.
