New in wrap stripped Colt M4 flat top upper receiver. This is a recent production upper receiver that I purchased from a reputable Colt Defense distibutor and yes it was really new in wrap when I got it. I have not used it however I did cut open the wrap and remove the receiver for inspection. Yes its nice and is marked M4 above the gas tube and has the usual M4 feed ramps. Please note there are no other markings of any kind anywhere on this receiver as it was intended to be used as a replacement part for Colt Military/LEO M4 carbines. I will include the original plastic wrap the receiver came in which is labeled Colt Defense LL and lists a part number and stock number. The price is firm and fair at $205.00 plus shipping. Pics and references will be available only to a serious buyer. Please contact me via e-mail through the site or direct at CLM4@EV1.NET.
