Upper receiver is NOT included. Only parts 5/6/7 are included. 5 – Colt gas deflector 6 – stainless steel gas deflector spring 7 – aluminum tube to prevent the gas deflector from shifting forward. You will only use part 8 from your original FE upper.
I used a strong rare earth magnet to remove the original port door pin from the upper.
I can install this for you if requested when you order a barrel and FE Retrofit kit or complete upper.
Thanks to ‘zentradi’ on AR15.com for the idea.
