I believe mine originally had just a roll pin to keep the end cap from rotating.
At a later date I tapped the hole and installed a 12-24x1/2 cap screw to secure the end cap.
How did they secure the handguard cap in place with no gas tube? I though about tapping the gas tube port in the FSB and using a screw but open to other ideas.
Thanks!
I have a Colt SMG parts kit. The handguard cap is secured by the fsb. The fsb holds it in place against a step in the barrel. The barrel is slightly larger in diameter behind the handguard cap no need for gas tube screws etc.
