but the plastic nosepiece is not interchangeable between the regular vs lock.. so make sure you get a radarlock version. i also found out there is a chance that regular lenses can fit into radarlock fames. just needs a bit of "Adjusting" of the lens at the nosebridge section of the lens that clips into the plastic nosepiece. as-is, the regular radar lenses will sit in a radarlock fame, but it wont clip properly into the nosepiece.
