For starters, your list of downsides to the SCAR is far from comprehensive. Also your opinion of its reliability appears to be misguided. Do you have any MRBF (mean rounds between failure) data to back it up?

I was intially excited about the SCAR, on AD. After, when we got one in at Magpul, I was quite disappointed. There is actually not too much to like on the SCAR, nowhere is it innovative. Except in marketing of course...anyone else see the SCAR ad parody which has every word as "Operator". Hilarious.

Furthermore, your use of the term "gas blowback" is incorrect. You were probably looking for "gas impingement".

Also, both your premises (1&2) are wrong. A nomex glove or AFG will not cure a burn problem, and the charging handle getting snagged on something and pulling the bolt out of battery is not the main problem with the charging handle. The problem is it will snag on something while you are firing it. The solution, however, alleviates both scenarios, being to make the charging handle non reciprocating. This was not done for a number of reasons, which FN fanboys say is because SOCOM specifically requested a reciprocating handle, but I have differing opinions.
