The FN-SCAR is the obvious choice to replace it. FN already makes the superb machine guns the Army uses, and previously designed and manufactured the FN-FAL "the right arm of the free world", a weapon that was issued by something like 50 nations in world. (None commie, either).

So, they took all their knowledge and designed a modular weapons system that has both a .223 and .308 version.

The SCAR has been tried and found wanting in the Sandbox.

We're stuck with the AR platform for the forseeable future I'm afraid.

The 308 should be the weapon of choice, one round they stay down.

Unforrtunately the FN-SCAR costs $2,799 new to civilians the last time I saw one for sale. The military M-16 is less than half that cost to civilians in the AR-15 version.
