We worked with the guys at SAP to get us these bags. Starting with their Run N Gun bag we removed the rubber material and replaced it with a hand strap to aid in stability when using the medium height side of the bag. This is one of the most versatile bags available right now. You can use it as a standard rear bag, a barricade bag or even strap it around your ankle to make those kneeling shots a bit easier.
