Up top, you get a Sig Sauer Romeo 4T red dot and an Olight PL-3 Valkyrie weaponlight already mounted and zero-ready. The Romeo 4T is a duty-grade sealed optic with long battery life and a bold reticle that’s easy to pick up from awkward positions, while the PL-3 delivers a powerful, focused white light for threat ID and low-light work. Together, they turn this MPX into a complete, ready-to-run personal defense or PCC-style range setup—no extra shopping required.
Whether you’re looking for a compact home-defense tool, a truck/PDW companion, or just a soft-shooting 9mm platform that’s a blast on steel, this MPX package checks every box. Add your choice of sling and you’re essentially done.
