📖 History of the MA40

The MA40 Individual Personal Weapon System is the successor to the long line of MA-series rifles used by the UNSC. Introduced in Halo Infinite, it represents the "Gen 3" era of Spartan equipment. Known for its rugged reliability and distinctive integrated ammo counter (represented in this model), the MA40 is the quintessential weapon for any Spartan-II or Spartan-IV deployed on Zeta Halo.

🛠 Functional Use & Cosplay Prep

This model is designed with the cosplayer in mind. It is separated into logical parts for easy printing on standard build plates.

• Assembly: Designed for easy alignment and gluing.
• Durability: Thick-walled sections to ensure it survives a full day at a convention.

IMPORTANT COSPLAY TOOLS: Since this is a 1:1 scale prop, sizing is everything.

• Electronics: The hollowed-out sections of the frame are perfect for remixing with LED kits for the ammo counter or tactical flashlight.
• Prop-Bashed: Use the barrel or stock for other Sci-Fi Blasters, Cyberpunk weaponry, or Space Marine fan-art projects.
