Dual fixed S.I.M. sling: The Dual fixed SWAT/IOTV/MTV bridged S.I.M. SLING-TM is a single point sling which is designed to be attached to both shoulders of an operator's ballistic (SWAT), IOTV, MTV, LBV, or Molle style vest or plate carrier. This configuration evenly and VERY comfortably attaches the weapon to the customer's vest in a single point configuration, perfect for MOUT operations, yet positioned precisely to remain on your ballistic vest while mobile in a vehicle or aircraft. NON ADJUSTABLE.
