I'll bite.

First a point of definition: I consider a rifle is a shoulder fired firearm with a barrel length of at least 18 inches. Super SBR's are long pistols not rifles!

Make mine the Mark 14 Mod 0 EBR, an updated M14, the longest serving rifle in US military history.

See: link

I carried one of the original models and fell in love with it. So what if it was heavier then the M16, the weight was worth the punch. And now that the M16 varients have all gone to heavier barrels the weight difference is even less.

And BTW, the 7.62 x 51mm NATO is the military rifle cartridge that all others are judged by. <img src="/ubbthreads/images/graemlins/smirk.gif" alt="" />
