UniKeys x BSUN Waves Rail Bottom-Out Linear

UniKeys x BSUN Waves Rail Bottom-Out Linear pairs a POM top and bottom housing with a Y3X stem using BSUN's rail bottom-out design, contacting along the housing rail rather than a conventional stem base. Newer tooling is used to keep stem wobble low.

Its sound is medium-pitched and medium-volume, fuller and less clacky than HMX's Snow Crash. Factory lube is applied selectively: only the upper stem sliders are greased, with legs, lower sliders, and spring left dry-film treated to avoid pooling.
