I bought a set of AFV club big foot Bradley tracks for use on DML's M270 MLRS kit. I understand Bradley, AAV7, and M270 MRLS uses the same tracks and drive sprokets. But DML's old M270 MRLS kit has old style drive sprokets for older pre-Bigfoot tracks that doesn't fit the new big foot tracks.

Does anyone know if it is possible to modify the old sprokets to fit the new tracks? If not, does anyone know if there are aftermarket replacement sprokets for the Bradley, AAV7 and M270 that will work with AFV big foot tracks?

It's possible to modify anything.

I have several dozen leftover Bradley sprues. If the pitch on the Bradley sprockets works for your track, you are welcome to the sprockets free of charge. Of course, they do look different, but if they work, you could cut the sprocket ring from the Bradley part and replace the one on the MLRS part. I'm looking at both right now and it doesn't look difficult at all.

I am not sure if it is the same pitch as before. I think Tamiya's M2 sprocket has 16 teeth, which is one more tooth than on photos of Big foot sprocket.

I've got a set of the Big Foot track. I'll just put some together and see if it fits.
