The Arc Weight is the first full-metal, Gen-like Layer Weight. Arc's burst stopper functions like Gen while providing an additional 7g weight boost.
Arc's design is inspired by Iron Man's first arc reactor and can be inlaid with a 5mm gemstone (compatible gems purchasable here:
https://amzn.to/3zkWEfF). The weight is cast in steel and available in bronze, nickel and gold plating surface finishes.
Arc is fully compatible with the new Nano Layer Weight (

WARNING: Use of Arc with painted disks may result in paint chipping and is not recommended.
