The MCR Safety Swagger SR4 Safety Glasses, Gun Metal Frame with Blue Diamond Lens (MCR Safety part no. SR438B), bring a lightweight, athletic look to range-day eye protection with a standout mirrored finish. Core elements of the SR4 series include a lightweight dual-lens frame design, athletic bayonet temples, and soft TPR permanently bonded all the way from the temple tips to the nose pads for a secure, comfortable fit through a long session. The SR4 line is fully dielectric, meaning it contains no metal pieces at all, a detail that matters around electrical work as well as on the range. This pair’s blue diamond mirror lens pairs with a gun metal frame for a distinct look that still meets the same lifetime frame warranty as the rest of the SR4 line.
