I've actually got 3 sets of windscreens that fit the Audix M series. The ones pictured above and a smaller set that are about 1/2 the exterior size of the ones I measured for Gutbucket came with the M1280s I got from mterry. I also bought a set of M1290s from the YS that came with the original wood boxes and included a tiny set of windscreens that are much thinner and about 1/2 the size of the smaller set from the M1280s. I don't think I've ever used the smallest set, but the 2 larger sets have worked quite well for me both indoors and outdoors.
