yeah, i saw that 416, and i have to say its a very reasonable change versus the gas blowback system on the current M16/M4. i like HK stuff a lot and IMHO i do not think its all hype. the 416 upper receiver costs very little more than a standard upper receiver of a 16/4, yet the govt does not want to give this enhancement to the (IMHO) crappy M16/4. i know this push rod system has been used in many weapons in the past, and its use should be utilized in places like baghdad.
i want to personally get an HK G36K and i know where i can do so, but it will cost a bit. so socom is buying sigs? no more Mk23's?
