Recently, Magpul’s new products have been arriving one after another. Please be patient if the products have not yet arrived. I know that everyone has been waiting for a long time...it will be soon~ Among the new products in January, the most eye-catching ones are besides the Flying Gloves 2.0 These are Magpul Summit / Terrain bulletproof polarized glasses! Since they are highly impact-resistant lenses, they must comply with certain specifications such as ANSI Z87.1 and Mil-PRF32432. This is also described on the Magpul official website . It complies with ANSI Z87.1 and Mil-PRF32432 standards. At the same time, the web page shows a video of the glasses being impacted by a bullet.

So what is ANSI Z87.1?

The full name of ANSI is " American National Standards Institute ", which is a non-governmental organization in the United States. Z87.1 is the specification number. ANSI has developed a series of specifications to determine whether goggles can withstand high-gravity impacts. It can be roughly divided into Z87 and Z87+.

• Z87 specification: cannot withstand high gravity impact
• Z87+ Specification: Is able to withstand high gravity impacts

To comply with the Z87+ specification, the lens of the product must be able to withstand the impact of the steel ball, hitting the lens but not penetrating the lens or shattering due to the impact of the steel ball. It describes the shooting conditions of the steel ball: 1. The shooting speed is 45.7 m/s 2. The steel ball weighs 1.04 grams 3. The steel ball diameter is 6.35mm. Being able to withstand the impact of such conditions can be regarded as an industrial safety level, and it must be able to withstand attacks from metal fragments in the environment.

What is Mil-PRF32432?

MIL-PRF 32432 is a US military standard specification. To meet this standard, lenses must be able to withstand the impact of the following conditions:

• A .15 caliber bullet impacts with a velocity of 640 m/s
• .22 mirror bullets impact at a speed of 550m/s

Only lenses or products that can withstand the above conditions are products that meet the MIL-PRF 32432 specification and can be certified as military-grade equipment.
