AR15-22 Blowback Muzzle break?

[Mordred]

Ive seen a few of these on Youtube...a muzzle break that actually makes more recoil so that the AR15-22 bolt blows back with better force. Does anyone know where I can buy one of these or who sells them? Or are they just custom made jobs that I have to know the right person to get one?

I don't think I have seen a muzzle brake like that. The only thing I have seen that has increased blowback is mounting a suppressor.
