Haven't seen either sources product in person - I'm betting Fulton's are fine, SG might be a gamble.
I bought my last set from someone on Arf.com - I like the shorter length better than the A2, and I really don't like the collapsible stocks, pinned or not.
I ordered stuff from these guys many moons ago and they were not quick, but they were knowledgeable, affordable and nice...Back then I found them on Alta Vista and gave them a call....(no website). They have a lot of unique stuff in their warehouse...
