Reported in the latest Janes International Defence Review (Vol 40 Sept 2007 page 15). The US Army is holding trials at the Aberdeen Proving Ground to compare the M4 carbine with 3 other 5.56 competitors. They are the the FN SCAR ,the HK 416 and yes, the XM8. No I'm not making it up, buy,borrow or steal the mag and check it out. So, maybe the XM8 will live again.
