The Ultradyne Quantum Gas Block, Black is a gas block.

The Ultradyne USA UD .750 Gas Block allows users to custom tune their rifle's performance to a specific rifle and ammo combination for smooth and reliable function. Perfect for competitive shooters, this gas block allows for a smoother, cleaner, and cooler cycle that improves performance by leveling the feel of the shot and reducing recoil. This gas block is constructed from durable steel with a corrosion-resistant nitride finish.

The gas block sits on the barrel and feeds gas to the action. Check the barrel journal diameter matches the gas block, and have it fitted by a competent armorer.
