Dave, I remember the 1st time Sir. I have had some items in and out of stock just this morning 3 times. I think it is the new website interface that needs the kinks ironed out. I suggest being ready to complete the purchase on the spot as firearm inventory is trickling in and can sell out quickly if only a firearm or two is all that is in stock. Buds does have over 3 million registered customers. Cheers and hope you get one soon!
