MRGG 7.62mm 16" Bbl Black Rifle

Geissele 08-513B MRGG 7.62mm 16" Bbl Black Rifle

The Geissele MRGG (MidRange Gas Gun) in 7.62×51 NATO with a 16″ barrel is a purposebuilt precision platform derived from the VSASS family and optimized for missiongrade accuracy, durability, and modularity. The Geissele 08-513B 16inch cold hammerforged CRMOV steel barrel is chromelined for corrosion resistance and consistent performance, and is userinterchangeable between 7.62×51 NATO and 6.5 Creedmoor to tailor ballistics to the mission. A suppressorready Geissele flash hider lets the rifle run suppressed or unsuppressed without compromise.

The upper and lower receivers are forged from aircraftgrade aluminum and finished in Type III hardcoat anodize for toughness and corrosion protection. Ergonomics are modern and ambidextrous: oversized trigger guard for gloved use, flared magwell for fast reloads, and a fully ambidextrous control set. The Geissele MRGG Rifle ships with Geissele’s SSAE twostage trigger for consistent, repeatable breaks and a Nanoweaponcoated bolt carrier group for enhanced reliability. The Super Modular Rail (MK16) gives fulllength MLOK attachment and a continuous Picatinny rail for optics coalignment and nightvision setups. Recoil management is handled by the Super 42 braided buffer spring with an H2 buffer, and a Magpul PRS Lite on a milspec extension provides adjustable cheek height and length of pull.

In short, the MRGG blends precision barrel tech, a robust gas system, premium controls, and modular ergonomics into a rugged, adaptable rifle well suited to tactical, competition, and longrange roles where every shot counts.
