Gun Builder Simulator

Customize and fire hyper realistic guns in full 3D

Gun Builder Simulator is a detailed firearm sandbox that focuses entirely on customization and virtual shooting fun. Instead of fast-paced combat, it gives you a workshop packed with famous weapons and lets you tweak almost every visible part before taking them to a shooting range.

The arsenal is impressive, covering iconic models like the 1911 pistol, AR-15 carbine, Dragunov SVD, tactical shotguns, SMGs, and more. Each gun is fully unlocked from the start, with tons of attachments such as optics, reflex sights, lasers, lights, and camouflage options. This makes it ideal for weapon enthusiasts and airsoft fans who enjoy tinkering with builds rather than grinding to unlock content.

Once your dream setup is ready, you can test it with unlimited ammo, realistic muzzle flashes, smoke, and 3D ejecting shells. The sound design is punchy and satisfying, and the slow-motion option adds a cinematic flair to every shot. You can even use shake controls to fire, which feels gimmicky but fun in short bursts.

The simulator also offers a structured experience through over 150 levels and a dedicated shooting range, giving some goals beyond simple free play. Settings let you fine-tune how the weapons behave, from ammo limits and fire modes to motion speed, vibration, and visual effects.

On the downside, there is no story, tactical gameplay, or real ballistics simulation, so those seeking a realistic military experience may find it shallow. However, as a pure toybox for inspecting, modifying, and firing detailed weapons, Gun Builder Simulator delivers exactly what it promises and provides a surprisingly addictive way to experiment with virtual firearms.
