5 of 5 Barrel review February 9, 2024
: Brian H from Bristol, TN United States  
I placed the new items on my rifle last week and they looked great. Not only does it look great, but the rails and their locations are very functional I was able to add my light, secondary sight, hand stop, and sling without having to add any extra hardware.

Yesterday I finally got to shoot the rifle and it functioned better than expected. I would highly  recommend this set up to anyone wanting to add great additions to their rifle

4 of 5 Great Product/could improve communication October 1, 2020
: Christian from Scottsdale, AZ United States  
Received the product very fast and the quality is fantastic. The only recommendation I’d give is to increase the amount of information and communication to the customer on the status of the product.
