Built to deliver a reliable and satisfying secondary firing option, the Masterkey adds close-range versatility without sacrificing maneuverability or balance. Its streamlined form factor makes it an ideal underbarrel companion for competitive play, scenario games, or loadouts that demand flexibility.\u003c\/p\u003e\n\u003cp\u003eInspired by classic underbarrel launchers such as the M203 and GP-25, the Masterkey blends iconic military styling with modern foam-blaster engineering. Feeding from Silly Shells, it supports a wide range of ammunition types while delivering approximately 80% of the power of a Spring Thunder in a far more space-efficient package. As a hardware kit, it’s perfect for builders looking to integrate a functional, tactical shotgun into their existing platforms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Note:\u003c\/strong\u003e This listing is for the hardware kit only. 3D printed parts, shells, and mounting accessories are sold separately.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring-powered, Silly Shell–fed\u003c\/strong\u003e shotgun platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesigned for under-barrel mounting\u003c\/strong\u003e via standard Picatinny rail systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProvides an effective secondary \/ backup firing option\u003c\/strong\u003e for most foam blasters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInspired by classic underbarrel launchers\u003c\/strong\u003e such as the M203 and GP-25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpace-efficient design \u003c\/strong\u003edelivering approximately 80% of Spring Thunder performance\u003c\/li\u003e\n\u003cli\u003eIdeal for tactical builds, modular loadouts, and close-range engagements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"font-weight: bold;\"\u003eProduct Resources:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/shellingtonlabs.com\/wp-content\/uploads\/2025\/09\/bigUndermount_ProductionRelease_V3.1.zip\"\u003e3D Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.youtube.com\/watch?v=dfbuEUc4zUY\"\u003eVideo Assembly Instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.printables.com\/model\/880038-silly-shells-for-homemade-nerf-blasters\"\u003eSilly Shells\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUnderbarrel Masterkey Hardware Kit ONLY\u003c\/li\u003e\n\u003cli\u003ePiggyFoam K25 Spring\u003c\/li\u003e\n\u003cli\u003eLube\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eLicensed Retailer:\u003c\/strong\u003e Ideal Foam Blaster (IFB) is an authorized retailer for PiggyFoam.\u003c\/p\u003e","brand":"PiggyFoam","offers":[{"title":"Default Title","offer_id":47493429559534,"sku":"pgf-masterkey-hardware-kit","price":30.0,"currency_code":"SGD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/3883\/3646\/files\/masterkey__fullpiggy.jpg?v=1768286720","url":"https:\/\/ifb.sg\/products\/underbarrel-masterkey-hardware-kit","provider":"IFB.SG","version":"1.0","type":"link"}
