The Edge doesn't have a "rear" baffle, it has a coking ramp built into the back of the bolt handle, between it and the cut in the back of the receiver, this primarily extracts the case. As stated before the bolt head is the same. The front baffle is slightly different, not sure if they interchange.(I dont see why not.) As you can see in the picture the front baffle has a set cut in it to allow the bolt to travel further toward the rear.
