For a compact optic under $1,000 that pairs well with the MK-II’s Shield RMS footprint, consider a Shield-brand RMSc-series red-dot for co-witnessing with the pistol’s iron sights and low-profile mounting. The MK-II’s threaded barrel and aluminum frame make it well suited to suppressed target work and range carry where a compact, sighted platform is desired.

The MK-II combines suppressor-readiness, an ergonomic overmolded grip, and an RMS-compatible optic cut into a compact platform that suits precision-oriented range sessions and carrier-style use where a threaded muzzle and accessory rail are required. Its durable aluminum frame and adjustable sights allow the shooter to tailor the setup to their preferred optics and accessory choices.
