Won't stay secure to barrel under recoil - Angstadt Arms Ultra Light Handguard

As others reviewers mentioned, this handguard doesn’t remain securely attached. It loosens under 5.56 recoil and move forward down the barrel. It’s basically missing the torque plate which can be found in other handguards such as the ones found in Midwest Industries barrels. This may be okay for 9mm but I wouldn’t recommended for 5.56.
