Help me make sense of AR-15 barrel profiles.
First question:
Lightweight, government, M4, A1, A2, HBAR, standard, pencil...
All sorts of terms are used to describe the different barrel profiles available on various AR-15s, but I can't seem to find any sort of accurate, detailed description of what each of the terms mean. Can y'all shed some light for me? I'd especially appreciate quantified descriptions (barrel diameter measurements, or weights, or other such data), if that isn't asking for too much.
Second question:
I'm trying to build the lightest, handiest AR-15 possible, within reason. Which barrel profiles should I be interested in? I assume a "lightweight" barrel is what I want, but is this really true? Are there any issues I may not be aware of that I need to consider?
Thanks!
