FX Impact M3 mods

I have just received my FX Impact M3. I have read numerous articles and hints…. I guess I’ll just come out and ask..I one put an carbon fiber tube on the inner barrel, and then puts a tensioner tube with barrel support on is it necessary to go the full monte and put a barrel harmonic kit on?
This is just one of many questions to come, I would like to say thank you in advance for all the folks that have already started to travel down this road And have input to give.
