I ordered the PSA upper on Feb 8th, given a 15 day delivery time frame. Today is the 14th day. 16" Mid Length SS Barrel .223 Wylde Chamber 1/8 With the Nikon M-223 1x4 Scope it will wear, mount is a Nikon M-223 mount on a YH Riser W/O handguards So now I need, well everything else...... Overall 1st day never having fire it impression is very good. Seems to be a well built upper. Fit and finish appears very nice. For $359 I am happy with it. Time will tell but I have a good feeling about it. Thanks for looking.
