I have a new (and my first) AR and I am just chomping at the bit to get to a range to shoot it. But because of a bicycle accident that left me blind in my right eye, I have to shoot rifles left handed. I have seen some add on deflectors that can help throw the casing away from the face when shooting lefty but I didn't know if this would be an issue or not. Any other lefty shooters out there that can give me a head's up on this? Or even other problems I might encounter shooting lefty.
