An AR-related internet purchase from me will always be from a board sponsor or board member, even if it is a little more. I won't quibble about a few bucks. To the FalFiles sponsors goes my FAL business. AK related goes here and to the FalFiles AK board. I am not presently a paying member on any of these boards, but I buy a lot of stuff from their sponsors and I recommend new shooters support site sponsors when using an internet purchase.
I see new guys almost every week at the range and generally get asked for a source of something for rifles, so that stuff can multiply in a hurry.
Tapco doesn't get my FAL business anymore, but will still get AR/AK related stuff if I deem it prudent to do so.
D&R doesn't post their Nikon prices, which is very likely my next scope. Which is probably coming from SWFA.
My co-worker just purchased a 4.5x14 Nikon Buckmaster from SWFA and was happy with the customer service, which was important, as he is a new shooter and was unsure of what he was looking for.
