Frequently asked
What weights does the HMX Nap come in?
Two options. The lighter build actuates around 37g and bottoms out near 43g, while the heavier build sits at roughly 45g actuation and 53g bottom-out. Both share the same housing and spring.
Does the Nap need lube out of the box?
No. It ships pre-lubed and the UPE stem is naturally slick, so it feels smooth stock. A light film application is the only tuning I'd bother with.
What does the UPE stem change about the feel?
UPE is a low-friction, self-lubricating plastic, so the glide is buttery and the sound leans soft and rounded rather than sharp.
