I like to have nerf battles in my backyards with my friends, sometimes 1 on 1. I also mod the blasters that my parents let me get (they think my 5 working blasters are enough).
Well, speak of the devil. I made my first RSCB today for my 3B. I personally love RSCBs for their low profile, rear loading, and ease to make. I'm a newbie myself, but I'm surprised how well my RSCB worked when I stuck it on. It is your choice though. Make what is the easiest for you.
