5 of 5 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.
