Brian, They are out of stock most places. Check the Radical Firearms website.--------radicalfirearms.com/

check with the major auction sites like G(un)B(broker) and G(uns)A(merica) Remove ()

Brian, these are about as rare as hens teeth currently Sir. I would check on large gun and accessory sites like (6)un (8)roker, Arms etc as discontinued and hard to find firearms and accessories show up for sale by private individuals and small shops. Just replace (6) & (8) with G & B. I would also use WIKIARMS to search online as well (first picture) : wikiarms.com/
