XYL Unicorn Mod Guide: Handguards, Stock & MPX Kit
Choose a handguard style, build the MPX stock conversion, and understand what the AEG buffer tube adapter actually changes.
Welcome to Monkee Mods
We’ll remember your pick and take you straight there next time.

The Monkee Mods XYL Unicorn Viper Handguard Kit is a 3D-printed aesthetic upgrade for the KM-9 Unicorn platform, styled after the M4 skin from COD Mobile rather than chasing a specific real-steel reference. If you've been running the stock Unicorn look and want something sharper and more distinctive on your build, this is a straight drop-in cosmetic change rather than a functional overhaul.
The kit ships with the Unicorn Viper handguard and the matching Unicorn Viper Handguard Body Rail, giving you both the outer shell and the rail structure underneath it. Note that the blaster, holosight, buffer tube, buttstock, and BCAR shown in product photos are there purely for illustration; they're not included and are sold separately, so budget for those if your build doesn't already have them. As a NEW ARRIVAL in our 3D Prints lineup, it's aimed squarely at KM-9 Unicorn owners looking to stand out from the stock look.
Choose a handguard style, build the MPX stock conversion, and understand what the AEG buffer tube adapter actually changes.
