I received the red rifles in the mail today. They look and work exactly like the pictures from NONNEF. Further, the sculpting is brilliant. The stock has just the right curve to fit nicely over the forearm and the barrel is prefectly shaped to sit above the roof of the car.
Now my Chromedome is holding his proper rifles and the TR weapons are safely put away for other uses (like adding weapons to my fan mode TR Megatron base). Although I do like using the seat gun as a Gundam style shield so I'll probably keep mixing things up as the mood strikes me.
