“Stay frosty, Spartan.” Add the trusted MK50 Sidekick to your real-world loadout with this handcrafted HLO prop replica, inspired by the sleek, rapid-fire sidearm from HLO. Whether you’re locking down an objective or clearing hostiles from Zeta HLO, the MK50 Sidekick is a symbol of precision, reliability, and Spartan readiness—and now you can bring this UNSC classic into your collection.

This full-scale replica captures the refined, tactical design of the Sidekick, featuring its compact body, modular frame details, tactical rails, and aggressive UNSC styling. The MK50 Sidekick is crafted true to its in-game proportions, offering a lightweight yet durable addition to your cosplay kit or gaming shelf.

Built from solid plastic with a stiff, durable structure, the Sidekick replica is designed to maintain its shape and resilience over time. It’s a static prop—the trigger does not move, and there are no electronic parts—ensuring safety at conventions and durability for long-term display.

Each piece is handcrafted and handpainted by our skilled artist team to capture the battle-worn aesthetic of UNSC gear. Matte tactical finishes, metallic dry brushing, and subtle weathering effects give the pistol a realistic, combat-ready appearance. From the engraved markings on the slide to the contoured grip, every feature reflects the practical, no-nonsense engineering style of the HLO universe.

Whether you’re finishing off a Spartan cosplay, outfitting your HLO collection, or just want to hold a piece of humanity’s finest tech, the MK50 Sidekick prop replica is ready for action.
