"No wonder our GI's can't get enough of them to fill thier needs anymore."
Since when are our troops looking for a larger, longer, heavier, rifle, with less out of the box accuracy, needs tuned up every 2 hundred rds to shoot 1 MOA, allows you to carry alot less ammo, etc etc.
Just because an old article from 5 plus years ago or TV show said once that the Marines are recycling old M14s for a less expensive temporary alternative for the basis of designated marksman rifles until they recieve the new rifles. Its doesnt mean they are rushing out to snap up every one in sight to make use of. Those old m14s they are recycling are for a single purpose (not at all to replace the M4 which is a far superior weapon for the modern battlefield), and require thousands in modifications, to build.
The recycled modified m14s were simply a temporary fix until the new designated marksman rifles showed up.
