Iron Sight Foundry Mod (1.21.1) – Craft Custom Tactical Firearms

Iron Sight Foundry Mod brings detailed 3D firearms and weapon part customization to Minecraft. It adds smooth first-person animations for checking magazines and clearing chambers during combat. Each weapon uses custom models that fit right into blocky worlds while delivering realistic shooting action. The mod also includes custom lighting effects so gunfire lights up dark rooms in real time.

Features:

• Adds detailed low-poly 3D models with clean mesh designs for all firearms.
• Includes smooth first-person animations for reloading, checking chambers, and inspecting ammo magazines.
• Lets you customize weapons through a deep attachment tree.
• Allows you to swap grips, change handguards, and mount scopes or tactical flashlights.
• Lets you slide accessories along rails to fit multiple attachments on a single gun.
• Changes weapon stats and transforms base guns into SMGs, assault rifles, or long-range DMRs based on installed parts.
• Produces bright muzzle flashes that illuminate dark caves and nearby blocks whenever you fire.
• Uses a custom GPU renderer built to run alongside Iris Shaders without visual glitches.
• Displays on-screen UI cues that connect directly with weapon inspection animations.
• Players using Yes Steve Model (YSM) should turn off the small on-screen player model rendering to avoid visual conflicts.
