Jim, not that I can find at online vendors. - https://gun.deals/search/apachesolr_search/026495708559 --- I would check the for sale sections at some large gun sites like (6)un (8)roker as discontinued and hard to find firearms and accessories are often listed for sale by private individuals and small shops. Just replace the (6) & (8) with G & B.
