Scale-up your Safariland® tactical carrier: The structured ballistic upper arms [set of 2] are an optional accessory with the ability to provide additional ballistic coverage of the shoulder, deltoid and bicep areas of the upper torso and arm. Options include a regular or short length [2 inches shorter than regular]. Comprised of durable 500-denier Cordura®, the structured upper arms provide improved ergonomic protection to the body. The low profile structured design rests more comfortably by cupping the shoulder, which increases overall fit, form and function. The structured upper arms are easily attached to the carrier via high-profile hook and loop platform to the shoulder strap component. Compatible with SX, Matrix, and Hardwire ballistics to complete the ballistic coverage that’s just right for you.
