When 5.56 runs out of steam, the Geissele Freedom Maritime Reconnaissance 6mm ARC 14.5" keeps going. Chambered in 6mm ARC, it pushes the AR-15 platform to genuine long-range capability without leaving the familiar lower receiver behind.

Built as a semi-automatic AR-15 rifle around 6mm ARC and a mid-length direct impingement system, the Geissele Freedom Maritime Reconnaissance 6mm ARC 14.5" delivers a proven AR-15 experience from first round to last.

Ballistic Upgrade Path: 6mm ARC delivers a genuine performance step up from 5.56 in both trajectory and terminal energy — a practical choice for shooters who've found the limits of standard AR-15 cartridges.

Competition Capable: Better long-range ballistics make 6mm ARC competitive in precision rifle formats and PRS-style matches where 5.56 starts falling short beyond 300 yards.

Lower Receiver Reuse: Your existing AR-15 lower receiver works without modification. A caliber-specific upper, BCG, and magazines are all that's needed to step into this performance tier.

Practical Hunting Cartridge: 6mm ARC bridges the gap between .223 and larger hunting cartridges — enough energy for ethical deer harvest at ranges the lighter 5.56 and .223 cartridges can't match.

  • Caliber: 6mm ARC
  • Barrel Length: 14.5"
  • Gas System: Mid-Length Direct Impingement
  • Handguard: 5" M-Lok Free-Float
  • Muzzle Threading: 1/2x28
  • Magazine Capacity: 30-Round
  • Finish: Type III Hardcoat Anodized
  • Origin: Made in the USA

Pairs with standard AR-15 lower receivers using a caliber-matched BCG and 6mm ARC-specific magazines. Standard AR-15 buffer systems and lower parts kits apply.

Type III Hardcoat Anodized over 7075 aluminum construction gives this AR-15 rifle solid corrosion resistance and a durable surface that holds up across a wide range of storage and operating conditions.

Built for shooters who want to push the AR-15 platform to longer distances — competitive shooting, medium game hunting, and precision training are natural roles for 6mm ARC capability.

Geissele Automatics is synonymous with precision — their Super Duty and Freedom Rifle platforms are actively used by U.S. Special Operations units and trusted by professional users worldwide. Made in the USA.
