The title is slightly misleading as they are not talking about a new type of rifle or cartridge. The M16 is being phased out in favor of the M4 which is already widely used. Interesting that they say the 20 “ barrel on the M16 is no longer needed due to improvements in ammo that gives similar performance in barrels as short as 10 inches.
Bah!
Humbug.
The 7.62 from the M14 turns “cover” with the 5.56 into mere “concealment”.
It just SHOOTS THROUGH more stuff to hit the bad guy. What you shoot it out of ain’t material to the conversation.
