Help - Sideway curving BB's, adjusting hop up.
I have an Echo1 ER25K. This thing shoots hard and far, but my BB's are curving towards the right. I'm loosing distance due to this, and obviously accuracy. I've read that cleaning my barrel and hop up, or re-aligning my hop up could fix the issue. Before I adventure myself into doing so, I would like to know how and what I should do.
