The first steps towards the C8A2 conversion of my TM M4 are complete. I installed a C8 metal body and have my furniture painted OD.
Next I want to get the heavy barrel. Thanks for posting that Lerch. Now I know what to get for the next part of my conversion.
I also installed a Modify torque-up gear set and a Prometheus MS110SP spring. Having a problem with it at the moment though. Once I got the mechbox installed into the lower receiver and got the motor installed, I connected the battery and test fired it to see if it was working (I'd previously had problems with the gearbox locking up. It worked like a charm. ROF was excellent too. I proceeded to finish assembly, and all of a sudden it didn't work anymore. I didn't try to see what was wrong though. It's too late tonight, so I'll have to troubleshoot it and pick it apart again on the weekend to see what's wrong with it. It may possibly just be the motor that needs adjustment. But it's looking good from a cosmetic standpoint.
