Added realism with ejecting shells! I learned about this gun on the DV Rebels VFX board and it is listed at Ehobbyasia.com. Anything that I can do in real life shooting situations is the best. You can always add ejecting shells in post but nothing beats the real thing. The gun ain't cheap; I'll do a review on it once I get my hands on one! Just another tool to add further realism for your no budget action movie!
