UMAREX GLOCK 19 Gen4 MOS BLK 6 mm CO2 NBB – 2.6509

Experience the perfect blend of compact agility, rugged reliability, and custom-ready versatility with the GLOCK 19 Gen4 MOS airsoft pistol. Engineered to dominate fast-paced skirmishes and precision-driven engagements alike, this sleek powerhouse sits naturally in your hand and delivers rock-steady performance from chaotic close-quarters battles to medium-range marksmanship.

Thanks to its built-in Modular Optic System (MOS), you can mount virtually any micro red-dot sight—Docter, Trijicon, C-More or Leupold footprint—using simple, swappable adapter plates (sold separately). When you prefer classic iron sights, leave the factory cover plate in place and zero in with absolute confidence. The MOS platform gives you tournament-grade flexibility: switch optics on the fly, adapt to bright daylight or dim indoor arenas, and fine-tune your pistol for peak performance in every environment.

A lightweight yet ultra-durable metal slide locks securely onto a reinforced polymer frame, marrying authentic GLOCK aesthetics with airsoft-specific resilience. Pronounced Gen4 finger grooves and a non-slip texture ensure a positive, controlled grip under pressure—even with gloves on. When your reserve runs low, an integrated backstrap piercing tool lets you swap out the 12 g CO₂ capsule in seconds, so you stay locked and loaded without missing a beat. Quick-field-strip design keeps cleaning and maintenance fast between missions, preserving peak reliability.

Inside, the realistic NBB blowback system delivers satisfying recoil and smooth cycling, sharpening your trigger control and building muscle memory. The non-marking polymer frame resists corrosion and field wear, while consistent muzzle velocity and tight groupings reinforce your fundamentals. An automatic trigger safety blocks accidental discharges, giving you complete peace of mind when every shot counts.

Measuring just 185 mm with a balanced 590 g weight, the GLOCK 19 Gen4 MOS hits the sweet spot between portability and stability. Its 12-round magazine feeds standard 6 mm BBs (0.20 g recommended) flawlessly, and its sub-2.0 J output stays within most field limits. Whether you’re a seasoned competitor, tactical trainer, or weekend warrior, this pistol elevates every mission with legendary GLOCK reliability, modular customization, and pinpoint accuracy.
