Hi,
Sorry I haven't got a pic of them side by side, I have a set on my mt4 and they are the same length.
I have no use for the nitro bits, so yes I could sell them but be aware I bought a 2nd hand nitro on ebay with the intention of converting it over to electric, I can not vouch for the nitro bits as I haven't used them and had no intention of using them, tbh I do not know anything about nitro but you are welcome to try
