Colt #1 Brownells
Great price on a hard to obtain genuine Colt product. Super fast delivery.

Good fit, no cage code.
Received 2 of these on back order early this year, 2024. 1 complete, 1 stripped. Both had keyhole forge marks, no cage code or other markings on receiver side. Top had "off" white T marks on top. Both had m4 marked above gas port. Tried both on an older LE serial # Le6920 lower and were a tight fit like my CK NHG upper. Happy with both but would like Brownells to identify manufacturing marks.

Misleading listing NOT CAGE CODED
Bought 2, both had keyhole forge marks and no cage code. The T numbers on top are sloppy. Got them on sale so I guess "colt" parts are better than Aero for the same price.
