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

The Geissele MRGG (Mid‑Range Gas Gun) in 7.62×51 NATO with a 16″ barrel is a purpose‑built precision platform derived from the VSASS family and optimized for mission‑grade accuracy, durability, and modularity. The Geissele 08-513B 16‑inch cold hammer‑forged CRMOV steel barrel is chrome‑lined for corrosion resistance and consistent performance, and is user‑interchangeable between 7.62×51 NATO and 6.5 Creedmoor to tailor ballistics to the mission. A suppressor‑ready Geissele flash hider lets the rifle run suppressed or unsuppressed without compromise.

The upper and lower receivers are forged from aircraft‑grade aluminum and finished in Type III hard‑coat 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 SSA‑E two‑stage trigger for consistent, repeatable breaks and a Nanoweapon‑coated bolt carrier group for enhanced reliability. The Super Modular Rail (MK16) gives full‑length M‑LOK attachment and a continuous Picatinny rail for optics co‑alignment and night‑vision setups. Recoil management is handled by the Super 42 braided buffer spring with an H2 buffer, and a Magpul PRS Lite on a mil‑spec 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 long‑range roles where every shot counts.
