Hey all, I don't really have a problem with it, but my TM m4 is only shooting at around 210 fps with .20's. How do i get that number up? does that require a whole new gearset/etc?

TM's run a little slow. Assuming everything else is OK, it's a spring upgrade. The downside is that you need to open the gearbox to do that.

While you are in the gearbox you should also check you compression. If the o-ring(s) on your cylinder head are bad you are loosing fps there, or through the nozzle where it meets the cylinder head, or where the nozzle rests in the hop up.

With that said PJ is absolutely right TM seems to shoot about 280 fps stock. If this gun is used the spring may have been left compressed for an extended time and no longer packs the power it use to.
