I have been a proponent of doing what they did in Israel, and take the AK, AR, FN and some other things, and piece them all together and produce one of the most successful weapons the world has ever seen, the Galil. (sp)
I know for a fact that there are better upgrades coming out for the M4, like see through mags ( was a big supporter ), and a match grade trigger. Chrome lined barrels, and maybe a free floater or two. And not just that, but getting away from the conventional mentaility and training all of their soldiers on a host of different weapons, not just ONE. That's the whole Soviet style training that we have had such a hard time coming away from recently.
Also, you guys need to realize that not EVERY war will be fought in the desert. We still have, ( last time I checked ) winter and arctic enemies, and also jungles and tropics. So the weapon to replace the 16/4 needs to be reliable in ALL environments, and so I can kind of understand where that pencil pushing general is concerned. Once we develop a weapon that meets all of those criteria, and alot more I am not even listing, then maybe, just maybe we are ready to replace the 16/4.
Oh, and we used the 14 not as a " quasi sniper rifle " but as a "designated marksman" rifle. Even used it to clear some houses, when the 4 jammed up. ....
