The HK36, which the XM-8 is based on, uses the tried-and-true AR-180 operating system, which has provento be quite reliable and not as susceptible to dirt and fouling as the M-16 action.
My own opinion is that it needs only some good iron sights and possibly an option to change the cartridge to .243 Winchester or .260.
Pic to follow...stay tuned, and bring all comments.
This rifle will be a serious infantry weapon, as our troops should ALWAYS have.
