High quality upper at a great price
Bough this on a black Friday special and arrived quicky. Everything looks great and assembled and shot exactly how I would expect.
The Mk1 AR-15 Assembled Upper Receiver comes with the port door and forward assist already installed. Forged from 7075-T6 aluminum, this assembled upper is precision machined to mil- spec M16/M4 specifications and features M4 feedramps.

Ordered this upper receiver to go on a griffin mk2 lower the fit and finish is great. They have awesome quality control.
Like the other review stated, no T marks, but I’m fine with that. Great fitment and uses a thermal fit for barrel extensions, which is always a plus for me
I bought both the lower and upper to do a Griffin build both receivers matched perfect and nice with no wobble. I am very pleased with the he quality of this upper.
Key hole forge mark, no T marks on picatinny rail. All in all a solid upper, I have no complaints.
