I was on the old AR15-L in 1999 and that must be my residual memory of Q3131(A) lot issues - thanks for the clarification.
DSOTM518, it was at 'The Trophy Room' on King Street in Alexandria, VA - they cater to the Beretta/Weatherby/Orvis and up set, but they do have a few things like HK and Beretta pistols in the back - and they do two very useful things for a shop that you'd think handles only the tassel-loafer-and-flyfishing crowd:
1) They will send an FFL for just about anything. AR15/AK47 receivers, they're happy. (They were closed the day before for a FONRA - Friends of NRA - banquet/fundraiser). They are happy to do it for me.
2) Transfer fee is the cheapest at a regular FFL in my area. I could spend less by driving only a considerable distance (and spending $ on fuel). It is a $30 rather than $10 fee, but considering the issues involved, I am happy to have two gun shops within a couple blocks of one another that cater to my interests! (The other, Potomac Arms, is one of those 'been around forever and always has estate/consignments' type of place).
Moral of the story - visit every gun shop you have free time to visit ;)
