G&G L85 A2 Muzzle Flash Hider issue

[Markyt001]

Hi all, I have an G&G L85 A2 and after yesterday’s game, I noticed the muzzle/flash hider is completely loose and appears to be missing a fixing to hold it to the outer barrel.

Would anyone know what should be holding it in place or a suitable method of securing it. Doesn’t appear to be a grub screw style fixing neither

Any advice much appreciated

It'll be a pin to secure it to the barrel.

It will need a role pin.
