Grendel LMG

[stanc]

That video Stan posted of the M27 during a USMC live fire shows why I'm not a big fan of a box mag fed LMG in the Squad.

The M27 also isn't anywhere near as controllable as designs that are now 80 years old, some of which were German. The Sturmgewehr itself remains one of the only controllable select-fire intermediate cartridge rifles if you look at constant recoil principle.

Another was the Stoner 63A. Watch how the gun barely moves even in the assault rifle configuration:

A couple of comments:

1. In the assault rifle configuration, the barrel centerline is lower relative to the buttstock than in the machinegun configuration, which aids in controllability.
2. It's Jerry Miculek! He makes even a .50-caliber Barrett look controllable in rapid fire. In the hands of a mere mortal, the Stoner LMG isn't quite as steady.
