Textron Systems NGSW Rifle and LMG

[stanc]

I am speculating that the True Velocity testing might be similar to the telescoping stuff as far as heat transfer. If I recall correctly the True Velocity stuff keeps the chamber much cooler than brass ammo.

Right. Polymer cases do not transfer heat to the chamber like metallic cases do.

Plus, the chamber of the Textron weapons is not part of the barrel, which helps.
