This is a hypothetical. The epic 1 is not yet available. The Mora is on its initial release. Now, I know epic, barrels are LW polygon or CZ . RTI uses LW or “proprietary “ barrels “ depending on caliber. Now Dave at Epic has been very forthcoming with info regarding the Epic 2. So I believe it will be the same with the Epic 1. Will RTI be as helpful? Now I have had ZERO interaction with them, and have yet to acquire one of their guns. Which means I can’t speak to that. But for a similar price gun 2-2400 bucks. I need to know, and I’m sure that I am not alone. What say you?
