Still no gun listed John, as far as not being able to select an answer, sometimes that button just disappears and im really not sure why, ice had it happen to me, if you want to stop getting the pop up message that you some times get you can remove the question there should be a button with that option on the page.
If you repost a new question and just put what gun your looking for in the text section " main body of the question " then we can help you find one. Buds website has been acting goofy lately.

John, you should be able to login to another browser on a computer/laptop to see the Pick Best Answer button. John, please do a search on (6)un (8)roker.com and Armslist for the model you seek 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.

John, I can't help you with the first part. As for the 2nd part, what gun are you looking for, there is none listed.
