From the manufacturer
Magpul set the standard with its MBUS back-up sights, and the company is taking it to an entirely different level with its MBUS 3 design, which is loaded with cutting-edge features in a durable, rugged package. The Magpul MBUS 3 Front Sight has been downsized, measuring only .44 inches high and 1.15 inches wide. Even though the sight looks like the MBUS Pro, this front sight has been crafted from Magpul's impact-resistant polymer, which saves weight while making it incredibly strong. A spring-loaded push button deploys the Magpul MBUS 3 folding front sight when needed, bringing it up to standard AR-15 sight height. You won't need any tools to adjust the elevation on this sigh Mfg: Magpul
