Nice upper receiver!
Haven’t used this in my build yet but it looks very well made! AR15 discounts was great as always! Good prices and great customer service!
USGood upper
Good upper with a close fit to my lower. Very little wiggle. It has the slot cut for the alignment pin the works with Centurion Arms handguards. The upper I recieved was mil spec cut, not thermal fit. The description did not say either way, so you are taking a chance on what you get. Centurion Arms makes them both ways. There are T marks in the top rail and a Centurion Arms logo on the side. Everything else is a good quality standard forged upper. No problems.
USCenturion Arms strip upper receiver
Excellent strip upper for any project. I will add to the description that is a Thermal Fit Upper Receiver.
