FINAL UPDATE, I put a little grease and I kept cycling the FC over and over 100+ times and it works perfect!!!! I got a little worried about the lower being poly but it wasn't that, plus my friend has the same one and has run 500+ rounds no problems what so ever!
But thanks agin Brothers in Arms for the guidance!!!!!!!
