10.99 here, 19.99 on web site, plus .40 "handing" and 8.16 shipping. So is this advertised price just a gimmick to get you to their site or just a screw up?

I quit buying from these guys, seems I could not place an order without them screwing it up. I order 2 barrels , get one , I ordered adjustable gas blocks get standard non adjustable. 3 orders , 3 issues , sorry No more business from me. Sadly their products are well made , fit and finish are great but it's a crap shot on what you might or might not get.
