Frequently asked

How light is HMX Serene Green?

Very light. It actuates at 42g and bottoms out at just 46g, with a small gap between the two, so the press is effortless and fast.

What makes it so smooth?

The UPE stem. UPE is a slick, self-lubricating plastic, so Serene Green glides exceptionally smoothly with almost no scratch even before you factor in the factory lube.

Does it need lube?

No. Between the UPE stem and the factory lube it is glassy stock — relubing offers little benefit here.
