I went ahead and called the factory, impressions:
1. The sales guy is reaaaally long winded. All I mentioned was a post to SKSboards and he gave me a lecture on why not to trust the internet. Then I told him it wasn't a blog, but a board, and he stated something to the effect that "they don't know what they're talking about". I can't remember, it feels like hours ago.
2. The HITECH Magazines are all fitted for your rifle apparently. You give them the make, serial, etc, and they dig up one of theirs that is of similar build and they make sure the magazines and adapter you order is as close to the spec of your rifle as possible.
3. They have a deal going right now where if you order one at the price of $95.00 (wow, you could get six tapco's for that price), they'll drop the cost of any magazine by ten dollars, and if you order four or more total magazines they drop them to $65.00! Still very expensive. Very, VERY expensive. I'm getting the feeling if they just dropped their magazine prices they could steal Tapco's market.
4. It takes two days to make the magazines and test them according to the sales-guy. Once tested and certified, they ship. No in-store sales. They apparently have US-Military deals going that prevent us from even visiting their factory. So if your in Fenton, your going to have to have them shipped anyway.
The main draw-back here is the price. For a $250-$350 rifle, spending $95.00 for a magazine and adapter, and the $65.00 for everything after that, we are talking big bucks. It takes a $540 to make this work if you spent $250 rifle, $640 for $350 rifle.
The idea and design seem sound though.
