What to know before buying

Listing details to confirm

The listing describes the body as Mg in one feature claim but lists ABS as the enclosure material. It also calls the optics BAK4 and FMC in promotional text, while the technical details list a roof prism and simply coated optics. Confirm the material and optical configuration if these distinctions matter. The package accessories are claimed in feature text but are not confirmed by a package inventory.
