In this episode I’m going to be reviewing the 14 upgrades installed on one of two of my Beretta CX4 Storm’s. I shipped my CX4's to Sierra Papa in Oregon to have eight of his after-market high performance upgrade parts installed. I also put on the Holosun HS506, Red Dot, Beretta Rail kit, Troy CQB Vertical Grip, Beretta Shroud and the Sightmark LoPro Combo Flashlight (Visible and IR) and Green Laser Sight. The rifle shoots like a dream! Check out the video and let me know what you think.
