I am looking for the old style M-16 A1 upper without the brass deflector and with the cutout for the auto sear. It should be in very good to excellent shape. Stripped or complete is OK. Anyone have one they don't need?

A cut out on the upper for an auto sear?????

The cut out is an area, actually a machined out area, is a oval that is located at the back end of the upper on the mating surface to the lower receiver. The sides of the auto sear on the M-16 protudes above the edge of the lower receiver about a 64th of an inch so the old style AR-15 A1 receiver without the cutout jams the auto sear.

The brass deflector is a part of the casting on the upper. It is a triangular shape that sticks out about 3/4 of an inch directly behind the ejector port. Does your upper have this?

Next look at the bottom of the upper where it mates to the lower. Just in front of the block that the back take down pin goes, the opening has a machined oval shape relief about 1/8 inch deep then the opening continues as a rectangular opening to the mag well. ???
