This is the second video we've watched that justifies the use of the real deal optics than replicas for use on airsoft guns. The Recon Brothers make the case why you should... "In our experience knock-off optics have the tendency to easily fail. In our frustrations we quickly learned to look for something better and here real firearm optics came in place. These genuine red-dots, holographic sights, telescopic sights and scopes are build to endure. And that makes them come with features knock-off optics can never compete against. With this video we'll go over those features to give you a better understanding of them and hope you will make smarter choices then we did."
