Fixing the mb4411d saggy barrel

Hey everyone! This is my first post and im new to sniping. I bought the Well MB4411D today but noticed one of the main con people were complaining about was that the outer barrel kinda sagged. Worried about it i made a very very inaccurate concept model of a sort of barrel stabilizer to print with my 3d printer .Do you guys think something like this would work?
