I have been trying to do a AR pistol build for about a year. I lack one item that hasn't been in stock almost as long. I need a stripped PSA upper Part#6123 for 69.95. This item is not in stock on the internet, but it is on hand at the brick and mortar store in Mt. Pleasant, SC. The salesman checked and sure enough they have alot of them on hand. They can't ship me one because they are not the internet store. I can come in and pick one up during normal store hours. I can't wrap my head around the problem. I know different inventories for each store become a nightmare for the stores if they don't keep them separate. Somebody needs to come up with a solution. I can't be the only customer wanting this part that doesn't live in SC.
