very impressed with the quality of the uppers. attention to detail shows very much in your work. My next build has only a couple specific details i would like to have and that is a Last round bolt hold design.

5 of 5 Great hand guard design December 14, 2019
: David Bristol from Cary, NC United States  
I really liked the quality and look of the product. Did arrive with a few scratches on the finish but nothing worse than other manufactures, even those with firearms over well over a $1K price tag.
