Good luck finding one. Internal parts for AEP's (other than piston. spring, head, spring guide, etc) are virtually non-existant. I have a Task Force MP7 a client brought in with a broken tappet plate and one of the spur gears is stripped and I have not been able to find replacments anywhere. My clients only options for repair are to replace the entire gearbox witha TM one (best option, but cost almost as much as the gun did) or find a broken donor gun that has good parts.
