Excellent product July 18, 2019
Reviewer: Jerry Lindquester from Clyde, TX United States  
I purchased this particular upper as my buddy got one he is slaying hogs with his.  It’s accurate and well built.  The one I received is also well built!  Fit in finish is excellent.  It mated up with my AeroPrecision lower perfect.

Excellent product April 21, 2019
Reviewer: Zach  
Ordered on a Tuesday and arrived Saturday of the same week. So great job on shipping. The upper itself is flawless. Finish is nice and even and in perfect condition. Much lighter than what you expect a 450 to be, so that’s nice as well. Functionally flawless as well. So far have tested it out to 200 yards and it holds  a 1.5” group consistently at that range, as well as 1” or better at 100 yards. Extremely satisfied and would recommend to everyone.
