M4 quietning

So I've just started into my new spotter role and I have a few questions. Any advice is greatly appreciated!

1. As I am working as a spotter I would like to make my M4 as quiet as possible so I don't give my or my shooters position away if I have to take a shot. I believe a silencer is probably a good place to start, but I have seen many different brands and types and I'm unsure as to their effectivness.

2.Also is there something I should do in regards to getting a new inner barrel? i.e one that will improve accuracy(not range)/sound suppression. With my current setup it is extremely hard to hit someone with one shot.

3. Stability of my weapon can also be an issue at times. I am considering buying a foregrip attatchment with a built in bipod to make for better stable shooting. If anyone has experience with using one could you please let me know if you thought it was useful.

Thanks! :tup:
