Just a clarification, Side Shot is not made by the owner of Utah Airguns. Side Shot is a completely separate and different company (about 2 1/2 hrs away from Utah Airguns)
Joe, I replied to your email at 12:58, that was before you even posted this. Yes, yours is fully rifled. That's why they call it the Impact X, because all impact X's have the STX barrel which is the rifled one.
