RE: Why are there such laws?!
It used to be, under the Gun Control Act of 1968 (thanks, LBJ!!), that you could only purchase a firearm in your state of residence. later this was expanded to permit the purchase of long guns in "contiguous states" if YOUR STATE passed a law to permit this.
However, due to the "instant check" system, you can now purchase long guns in any state you are in if you pass the "check telephone call", and there are no loal laws trhat prohibit the purchase. NOT handguns, though! (Now, how much sense does THIS make??)
IF you insist on buyingfrom Walmart, go to one in your home of record state, and have them order what youi want. Walmart has a gun catalog that lists everything in the firearms line that they stock anywhere. Remingtons are pretty universal items. Prices should be the same......
