USGI MOLLE 4000 Modular Belt System (MBS)

US Genuine Issue Modular Belt System (MBS) Belt, in new and unissued condition, for MOLLE II and MOLLE 4000 compatible field gear systems. Also sometimes called the Army Close Combat Belt Set (ACBS) and is very similar to the USMC Padded Sub Belt w/ Suspenders.

The MBS serves as a high-mobility modern fighting platform for "War Belt") and "Battle Belt" needs. It is a standalone tactical belt that ensures mission-essential combat loads for ammunition, sidearms, and trauma kits. It is specifically engineered to be low-profile enough to be worn under the hip belt of a heavy rucksack, enabling a seamless transition from a heavy march to a high-intensity engagement without losing access to critical equipment.

Features

• Weight: 2lbs
• System Components:
  • Modular Outer Belt (Padded Sleeve): The laser-cut or standard PALS/MOLLE padded sleeve that distributes weight and provides the mounting surface for gear.
  • Inner Rigger's Belt: A high-tensile nylon belt with a heavy-duty buckle (often a low-profile cobra or military-standard buckle) that threads through the sleeve to secure it to your waist.
  • MBS Suspenders: Low-profile, four-point suspenders that attach to the D-rings on the padded sleeve to help support heavy combat loads on the shoulders.
  • Holster Leg Extender: A specialized drop-panel that allows a holster to be mounted lower on the thigh, clearing the way for a rucksack hip belt or body armor.
• Ergonomic Padded Sleeve: The contoured outer sleeve features a breathable mesh interior and closed-cell foam padding designed to mitigate hot spots and prevent gear from digging into the hips during long-duration field use.
• Segmented MOLLE/PALS Interface: Features segmented webbing sections that allow the inner belt to be threaded either over or under the MOLLE panels. This provides the versatility to mount belt-slide holsters and sub-loads directly to the inner belt while keeping other pouches secured to the outer webbing.
• Compatibility: Generally compatible with MOLLE, MOLLE II, PALS, and MOLLE 4000 field gear.
• Low-Profile System Integration: Engineered specifically to work in tandem with the MOLLE 4K Airborne Rucksack, its slim profile ensures it fits comfortably beneath the rucksack’s molded waist belt without creating excessive bulk or mechanical interference.
• Heavy-Duty Inner Rigger's Belt: Includes a removable, high-tensile nylon rigger's belt with a reinforced stiffener and a secure, low-profile buckle system to ensure the load remains stable and centered during dynamic movement.
• Four-Point Suspension Points: Integrated heavy-duty plastic D-rings are strategically placed to allow for the quick attachment of standard MOLLE suspenders, helping to distribute heavy ammunition or water loads across the shoulders.
• Mil-Spec Durability: Constructed from genuine 1000D Cordura nylon with IR-compliant (Infrared Reflective) webbing and NIR-signature management, built to survive high-abrasion environments and harsh combat conditions.
• Berry Amendment Compliant: Proudly manufactured in the USA by authorized Department of Defense contractors to meet strict CO-PD-02-02 military specifications.
