WTB Slick side A1 Upper Black preferred. Lg or Sm front pin

[Corpsegrinder88 1]

Working on a Colt 607 clone.. figured i would try to see if anyone here has an upper laying around. from either a SP1, Colt 9MM or some no name upper. doesnt matter really. but thought i would try here before going to GB or some other place. 

 

Thanks.
