Ops-Core A14745-1 Mk1 Standard Inserts

While Ops-Core Mk1 Performance Protective Eyewear is durable, sometimes-severe elements and use can take its toll. To keep your eyewear operating at peak performance, be sure to replace worn out frame inserts. Ops-Core Mk1 Standard Inserts securely and interchangeably mount your Mk1 lenses in the frames. Should your mission require it, you can easily add additional protection from wind and dust with the Ops-Core Mk1 Foam Inserts. All inserts provide a lightweight seal, and include a comfort Nose Bridge.
