The GiRSAN MC312 is a 12 Gauge Inertia Driven Semi Automatic shotgun. This amazing shotgun features a 3.5″ chamber meaning you can shoot either 2-3/4″, 3″ and 3-1/2″ shotshells. This proves to be a difficult task because it requires the bolt to cycle back far enough to the 3.5″, but using only the energy from a target load2 3/4″. EAA has put these guns through their paces with a 700 round continuous round torture test with mized and matched ammo inside a single magazine tube. Moreover the first 5000 rounds ran with zero cleaning and on top of that a 10,000 round endurance test without replacing any parts. This shotgun passed with flying colors. If that wasn’t impressive enough 5 shotguns were disassembled with all the parts placed in a single box. After mixing up all the parts and re-assembling all the firearms randomly the MC312 fired with no adjustment needed. This impressive test is enough to satisfy even the toughest of critics.
