The Army is about to roll out a smaller carbine as part of its new, multi-billion-dollar rifle system. A slightly shorter and lighter carbine version of the M7 rifle, the Army confirmed, is now close enough to fielding that it has been given its own name: the XM8.

Troops tapped for early testing of the new carbine should start to get their hands on the first XM8s as soon as October, an Army spokesperson told Task & Purpose. The XM8 shares internal firing components with the Army’s new M7 rifle, firing a 6.8 x 51mm round...

Doesn't look that much shorter. Also wasn't the whole point of shifting to this calibre to have more velocity for longer engagements and to defeat body armor? So they shorten the barrel which reduces velocity. Makes perfect sense.

Still a football bat.

I know weapon designations are not manufacturer specific, but ‘XM8’ was already used for the 5.56mm carbine project of the mid-2000’s. HK’s 5.56mm carve out from the OICW project had the XM8 title, and was seen at the beginning of the movie XXX: State of the Union.

They couldn’t have picked a different ‘XM’ flavor??

There can be only one XM8.

A slightly shorter and lighter-weight carbine version of the U.S. Army’s new 6.8x51mm M7 service rifle has now gotten its own designation: XM8. This choice of moniker is somewhat interesting, given that the service previously applied this designation to an abortive modular family of firearms designed to ape the looks of the guns in the 1997 movie Starship Troopers. The M7 had faced some significant criticisms of its own previously over its weight, ergonomics, and other aspects of the design, which the Army and manufacturer Sig pushed back strenuously against. At the same time, the design has continued to evolve and has been fielded more widely, as evidenced by the carbine version...

Still a totally garbage design for the handguard to receiver interface. The Spear is dead in US mil inventory. Serious end users know the detractors of the rifle and optic and have sidelined them.
