Beez Combat Systems Big Rig Gustaf

The BIG RIG Gustaf is the dedicated 84 mm Carl Gustaf M3/M3A1 ammunition insert kit for the modular Big Rig load carriage platform. It integrates seamlessly into the Big Rig’s laser‑cut GRID panel, converting standard external frames into a purpose‑built kit for hauling M3A1 MAAWS rounds

Key Features & Benefits

  • 4‑round capacity: Includes two laser‑cut laminate inserts that securely retain up to four 84 mm rounds using dual-flap & buckle retention
  • Adjustable secure fit: Each insert uses 1″ MIL‑Spec webbing and side‑release buckles to conform to varying round profiles and protect cargo
  • Quick access design: Open‑sided inserts enhance access to protective round casings without needing to remove the entire kit
  • Durable build: Crafted from laser‑cut laminate, MIL‑Spec thread/webbing, and buckles; fully built in the USA
  • Balanced load distribution: Two inserts spread across the Big Rig’s GRID for optimal center-of-gravity and comfort.

Tool & Equipment Integration

  • Big Rig Platform: A mission-configurable carriage that attaches to common military external frames (e.g., MOLLE, ALICE, FILBE). It features strap management, tail compression, grid compatibility, multiple lashing points, and a carry handle.
  • Big Rig Insert Kits: Besides the Gustaf variant, insert options include medical gear and hydration systems — all compatible with the same Big Rig platforms.
  • M3A1 MAAWS (Carl Gustaf): Originating from Swedish recoilless rifles, the M3A1 MAAWS is the modern US designation for Carl Gustaf systems, featuring reduced weight, improved ergonomics, and advanced fire control capabilities, notably compatible with programmable FCS‑equipped rounds

Operational Advantages

  • Fast deployment: Rounds are retained yet easily accessible—ideal for rapid M3A1 reloads under fire.
  • Modular adaptability: The GRID setup supports mission-specific kit swaps (e.g., recon drone gear, crew‑served weapons, medical or hydration inserts).
  • Enhanced ergonomics: Balances heavy 84 mm rounds effectively across the pack to reduce fatigue during sustained operations.
  • Tactical readiness: Ensures MAAWS teams have mission‑ready equipment configured specifically for anti-armor and anti-personnel engagements.

Typical Use Case
A two-person MAAWS team can designate the gunner to carry the M3A1 launcher and the assistant to haul the Big Rig Gustaf kit. This division aligns with standard doctrine: one operator handling reloads and spotting, while the other manages the launcher. Ultimately, the Big Rig Gustaf enhances reload efficiency, survivability, and load modularity—critical in high‑tempo combat scenarios.

Why It Matters for M3A1 MAAWS
The M3A1’s flexible ammunition suite, including HE, HEDP, HEAT, smoke, illumination, and programmable air-burst rounds with advanced ballistic sights, demands organized, rapid access to rounds. The Big Rig Gustaf ensures soldiers can carry and deploy four 84 mm rounds efficiently, preserving both equipment readiness and human endurance.
