Product Details
Colt's Manufacturing Part Number SP63528. Flat Top Upper Receiver with M4 Feed Ramp, Dust Cover and Forward Assist installed.
New in box, Mil-spec quality straight from Colt!
This is a new part direct from Colt. They are as listed in the above description. Markings do vary from batch to batch. Sometimes they are the keyhole, and other times they are the square. I know many Colt collectors care more about the particular marking than the quality of the part itself. If that is the case, we recommend you purchase on Gunbroker, or another site where you can see a picture of the exact part you are buying. We are unable to hand select for specific markings.
