Geissele MRGG (Mid‑Range Gas Gun), 7.62×51 mm NATO, 16″ Barrel – Black is a precision-engineered rifle born from the Very Long-Range Semi-Automatic Sniper System (VSASS) family. Designed for elite performance, this rifle features a 16-inch cold hammer-forged CRMOV steel barrel, chrome-lined for enhanced durability and accuracy. The barrel is user-interchangeable between 6.5 Creedmoor and 7.62×51 mm NATO, offering flexibility for mission-specific needs. A Geissele suppressor-ready flash hider crowns the barrel, ensuring optimal performance with or without a suppressor.

The MRGG’s upper and lower receivers are precision-machined from aircraft-grade aluminum and finished with a Type 3 hard coat anodize for superior strength and corrosion resistance. It includes a fully ambidextrous control layout, an oversized trigger guard for gloved use, and a flared magwell for rapid reloads. The rifle is equipped with Geissele’s SSA-E trigger for crisp, consistent pulls, and a Nanoweapon-coated bolt carrier group for unmatched reliability. The Super Modular Rail (MK16) provides full-length M-LOK compatibility and a flat-top M1913 Picatinny rail, ideal for co-aligned optics and night vision systems.

Additional enhancements include the Super 42 braided wire buffer spring with H2 buffer for reduced recoil and extended spring life, and a Magpul PRS Lite stock mounted on a mil-spec receiver extension for adjustable comb height and length of pull. Whether for tactical operations or precision shooting, the Geissele MRGG delivers cutting-edge performance in a rugged, adaptable platform.
