You just simply buy an extend barrel to screw it on also get a new hop up until for shot and long barrel, just in case you are lazy to take in and take out the rubber and knob for the hop up when switching barrel all the time and it would lost sometime too. Make sure you choose the right cylinder, choose the one that can compatible for M4 barrel and M4 CQB,

Here is the example.
