Well MRT/CQB stock gear ratios

Does anyone know the stock gear ratios? I was thinking of pitting in a set of metal gears and I am happy with the current ratio.


18:1 mate, I did the same with SHS gears.

Pretty sure most if not all blasters come stock with 18:1

Thanks. I will check with M4A1 if they have that gear set in stock. Will I need shims, or can I use the ones off the nylon gears?

Likely you’ll need to reshim

You definitely need to shim your gears, most nylons gear sets don’t have any shims and if they do they 100% be wrong from your new gears
