We have a limited number of Leica black dot logos, for M6, M7, etc. These are original factory red dot logos, but the red paint has been stripped and replaced with a semi-gloss black ceramic coating. Email to order, these are $75 each. Alternatively, send us your red dot and we will paint it!  We will paint them in batches along with other gear, so it will be a few weeks turnaround. Contact us for more info.
