A bull-pup assault rifle featuring a S-E-F trigger group, and a cocking handle placed "under" the carrying handle. It can be reconfigured for left-handed users. It uses 20-rounds STANAG 5'56x45mm-NATO magazines and it is VERY light. As a result of its lightweight it was dismissed as a toy by the Brazilian Army's Testing Grounds.
