The Geissele Automatics MRGG MK1 6.5 Creedmoor 20" Rifle with Picatinny Rail is a purpose-built mid-range gas gun derived from the SOCOM-adopted VSASS program. Centered around a 20" cold hammer-forged, chrome-lined threaded barrel and a full-length Picatinny top rail, this rifle is engineered to deliver bolt-gun precision with semi-automatic speed. The RRS ARCA-Lok compatible MK18 handguard, ambidextrous MRGG receiver set, and HUXWRX 7.62 flash hider create a refined platform ready for precision optics and suppressor use where legal.

This MRGG MK1 configuration in 6.5 Creedmoor is ideal for shooters focused on long-range accuracy, practical competition, and extended range sessions. The MRGG SSA-E two-stage trigger, reliability-enhanced BCG, Magpul PRS Lite stock, and Geissele A22 grip support stable, repeatable shooting from prone or supported positions. Whether you are building a precision gas rifle setup for training or open-country hunting, the MRGG MK1 reflects Geissele’s reputation for meticulous machining, thoughtful design, and durable performance.
