Also known as: AMAC-5100, M600 Special Applications Rifle
Overview
The Ramo M600 is an American single-shot bolt-action anti-materiel rifle distributed by Ramo Defence. The rifle traces its design lineage through several American companies including Iver Johnson (as the AMAC-5100), Daisy Weapon Systems, and Redick Arms Development. Available in three powerful chamberings (.50 BMG, 12.7x108mm Soviet, and 14.5x114mm Soviet), the M600 is a manually operated rotating bolt-action single-shot design weighing approximately 10.4 kg empty. The 813mm barrel delivers full ballistic performance from the .50 BMG cartridge. The M600 is the single-round variant of the magazine-fed M650, which uses a 7-round detachable box magazine. Despite its modest weight for a .50 caliber platform, the single-shot limitation reduces its tactical utility compared to magazine-fed competitors.

Notes
The user originally identified this as a Spanish rifle, but research confirms the Ramo M600 is of American origin, with its design heritage tracing through Iver Johnson, Daisy Weapon Systems, and Redick Arms Development before being distributed by Ramo Defence. The M600 is the single-shot version of the design, while the M650 variant adds a 7-round detachable box magazine. The ability to chamber three different large-caliber cartridges (.50 BMG, 12.7x108mm, and 14.5x114mm) through barrel swaps made it versatile for different operational requirements.
Background
The Ramo M600 has one of the most convoluted corporate histories of any firearm, passing through the hands of Redick Arms Development, Daisy (yes, the BB gun company) Weapon Systems, and Iver Johnson before being distributed by Ramo Defence. Its ability to fire .50 BMG, 12.7x108mm Soviet, and 14.5x114mm Soviet through barrel changes made it a versatile but obscure player in the anti-materiel rifle market.
