So I have seen some on the Skout Airgun - Epoch. What are the thoughts on this? It looks amazing. Little confused about the electronics and controlling the "dwell" would love some more information on the importance of it; is that the same as using a Plenum? Also, does it come with 3 different size barrels???? I saw on FB someone posted about that. Awesome piece of machinery, need it in my Airgun Arsenal!
