Nice. It's about time we got some proper models for the heavier weapons ingame.
Tho, as nice as the model is, I'm personally not a big fan of barrels on energy weapons (esp. heavier ones). This thing would be perfect for some heavy ballistics turret, but when it comes to Mortars, they're basically charging up a massive ball of energy and spitting it out, so imo a railgun-like design (the scifi energy weapon type, not the modern day slug shooter) could probably reflect that type of functionality much better than a barrel.
