The M16 H-Bar will be several pounds lighter than a M249 so fitting accessories such as night sights is less of a burden. The weapon might also mount the M203 if this was desired.
LMG versions of Assault rifles, sometimes called Machine Rifles have been used by many armies, probably the best known being the RPK. Many armies have also used the FAL-HB alongside their FALs (SLRs) and MAGs (GPMGs).
Heavy and Fluted barrels for the AR15 have been available for a long time and several nations already use the M16 in an LMG role. Heavy Barreled versions of the M16 are in use by Canada, Brazil, El Salvador, the Dutch Marine Corps and the US DEA. The USMC experimented with M16-LMGs.
