Richard, no eta's Sir. Just place the item on both your Notify Me and Wish Lists for notification when back in stock. I would check on large gun and accessory sites like (6)un (8)roker and Armslist 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.

Unfortunately buds doesnt receive Etas on when or of items will be back in stock, always make sure to hit yhe "notify me when available button and act quickly if you get an email telling you its back in stock.
You can also keep a. Eye in auction sites like(G)un Br0ker, or private party sales sites like Armslist.com
