    Quality Handguard.

    Posted by Khory Holliday on Dec 10th 2023

    I was searching for a handguard that would not only wrap around my suppressor but something that looked really nice also. When I saw this one I knew I had to have it. I actually purchased a basic handguard from a different site, had terrible service so I decided to send it back and purchase this one in the 12.6” length. I love it and the build turned out great!
