5 of 5 Amazing August 15, 2024
: Luke Malone from Lenoir City, TN United States  
The upper came out so well. Such a great upper for my first rifle it’s so pretty and I know I got quality parts. I got exactly what I ordered and I loved getting to pick out the parts I wanted. I also loved the added free coozie.

I am very impressed with the quality of this upper. I also love the way it looks! I got it with the 3C muzzle brake. I am glad I found this company, they are definitely legit

5 of 5 Great.... absolutely great September 14, 2021
: C B from Canton, GA United States  
Have been lookin at this handguard for awhile now when doing other builds and finally decided to get one..... glad I finally did... great look, lighter than you would think and the build in rails are perfect.... this build is in FDE...... I’ll get this combo again but I’m thinking instead of 5.56 I’ll do a 300blk in the grey
