This is a hypothetical variant of the M41A Pulse rifle. It's the Squad Automatic Weapon version (SAW). Made mostly of resin with vac-formed shrouds and some metal parts.
The trigger, safety, selector, and bolt are movable, and the shoulder stock is fully adjustable.
The shoulder stock, barrel and barrel vent are metal and the 300 round magazine "box" is removable. Business end...
