Plus, I purchased my Trijicon MRO for around $350 which is a great deal considering the quality of the optic. That combined with purchasing my ARX100 for $999 which also Beretta was running an offer for 5 free Beretta steel ARX magazines.
Thus for a total of under $1,400 spent, I got a Beretta ARX100 new with a Trijicon MRO and a total of 7 magazines. You can't beat that.
