Geissele Automatics 08379LB 6mm ARC 20" 6-Round Rifle

The Geissele Automatics 08379LB 6mm ARC 20" 6-Round Rifle represents a precision-focused platform engineered for shooters who demand accuracy at intermediate distances without the recoil signature of larger cartridges. Built on proven Geissele manufacturing standards, this rifle serves law enforcement marksmen, tactical competitors, and serious hunters seeking sub-MOA performance in a lightweight, controllable package. The 6mm ARC cartridge—a modern, short-action intermediate round—delivers supersonic velocity out to extended ranges while maintaining shooter control and minimizing collateral risk in sensitive operational environments.

This rifle features a 20-inch barrel optimized for 6mm ARC ballistics, producing velocity nodes that maximize accuracy across common engagement distances while keeping overall length manageable for vehicle-mounted and confined-space operations. Geissele's manufacturing precision—honed through decades of military and law enforcement contracts—ensures tight tolerances in the action, chamber, and headspacing that translate to repeatable sub-MOA groupings. The 6-round magazine capacity reflects practical tactical doctrine: enough ammunition for engagement sequences while prioritizing speed of reload and ammunition discipline. At 10.9 pounds, the rifle balances structural rigidity necessary for precision with portability demanded in field operations.

Operators and competition shooters will find this platform ideally suited for precision rifle matches, designated marksman roles, and hunting applications where controlled recoil and inherent accuracy matter. The rifle's dimensions (43.7 inches overall) and moderate weight facilitate use from field positions, vehicles, and supported shooting. Compatibility with standard AR-pattern optic mounts and accessory rails allows rapid customization for mission-specific loadouts—whether adding magnified glass, night vision devices, or alternative ergonomic controls. This rifle delivers the precision heritage Geissele is known for in a purpose-built 6mm ARC configuration.
