Has anyone changed the handguard on their Predator? I'm wanting to change mine to something similar to the G&G SRXL handguard. Is it possible to fit the SRXL handguard on the Predator? They're both 12" but I notice that the Pred handguard is clamped by two allen screws on the bottom where it looks like the SRXL handguard is screwed on either side. Pics attached for reference
