This new FNH PS90 rifle fires the 5.7x28mm round. It has a 16" barrel with an overall matte black finish. This semi-auto rifle has an ambidextrous charging handle, and an optics rail with a peep hole underneath it. Looking thru the peep hole you can see a front post situated just below the front of the optics rail. On these rifles the spent shell casings drop straight out the bottom of the rifle adding to the ambidexterity of this rifle. This rifle comes with box, lock, sight adjustment tool, manual, and one 50 round magazine.
