The AirsoftJunkiez Custom Expert Series MK12 DMR is a high-performance HPA build designed for precision and reliability. At its core, the rifle is powered by the Wolverine Inferno Gen 2 V2 engine, which is seamlessly managed by the Gate Titan II Bluetooth FCU for advanced programming and instant trigger response. The firing interface is further refined with a Nova Trigger and the Gate Tac Ticker, providing a crisp, tactile "break" with every shot. This internal configuration ensures the rifle remains consistent and quiet, meeting the rigorous standards of a dedicated marksman platform.

To maximize its long-range potential, the MK12 features a high quality hop-up and barrel assembly. It utilizes a PDI 509mm inner barrel paired with a Maxx HPA Hop-up unit, a Silent Blue Nub, and a Maple Leaf Flat Hop bucking for superior grouping and lift. The exterior is just as mission-ready, outfitted with a Daniel Defense vertical grip, a buffer tube with a crane stock, and a versatile PEQ box featuring IR, white light, and red laser capabilities. Topped with an ACOG optic, this build offers a complete, field-ready solution for players demanding professional-grade accuracy.
