ENARM PENTAGUN: Semi-automatic combat shotgun fed with a 6-rounds revolving cylinder. This was the ONLY ENARM weapon to enter in service with the army in Brazil (widely used by their Special Forces). It fires standard 12-Gauge rounds. A less-than-lethal version of this shotgun, shooting ONLY CS or anti-riot ammunitions, is manufactured by Quimica Tupan under the name AM-402.
