I actually disagree with the answers... 
1. Suppressors do work, if you put the right stuff in them. Some use foam and seems pleased with the results. All suppressors i've had have been working. They all muffle the sound. Not by making it lower, but it changes the pitch of the noise causing it to not travel as far as the higher pitched noise.
What i do to make them work properly is to take out the original foam and put in an old AEG-spring with burlap wrapped around it. Quite simple, to be honest. Just cut a sheet of burlap and wrap it around the spring, then put the spring back into the suppressor. Works like a charm.
2. Don't start with installing a new barrel. I'd clean the barrel like a nutcase and perhaps get a new bucking and/or nub.
3. IMO a bipod is not necessary, mostly for posing. I do recommend you to get a grip if you feel it's more comfortable and easier to hold the rifle.
You'll still have the noise from the gearbox, but that sound doesn't travel as far as the slamming sound from the barrel, which you muffle with a properly configured suppressor.
Just my thoughts on the matter.
