Yes it is possible. I do not have one on mine but I have seen them on a few freinds. I am not absolutely positive how but, I think there is a a bracket you can buy and either mount it yourself or have a gunny do it. It mounts to the side of the action and is L shaped to go over the top of the ejection port. The shells tend to eject a little to the right on mine. I have never seen any problems with ejection when my freind is cycling his action.
I personally would not and wont put one on mine. I don't think it needs it. But, its all in what you are comfortable with.
