I am in the first stages of putting together a light as possible AR. The lower is a Plum Crazy from JoeBob, and I want to match it with a lower cost lightweight upper. First question is how much weight do I save by using a pencil profile barrel as opposed to a standard M4 profile? Second question, are the Del-Ton and DPMS uppers of a good quality? Finally, where is a good place to purchase at the best price?
Thanks
Leon
