Gevarm rifles were made by the French Gevelot firm from the late 1950's to the late 1980's, or so. The Argentine Venturini rifle and the Voere 2005 are versions of this design. There are two basic series of these guns. The model A rifles have a cylindrical receiver with a fluted end cap, distinguishing them from the round backed "E" group. The charging handle lays on the right side, immediately behind the ejection port.
The typical model A3 was 41.25” overall, with 21.65” barrel, and 8 shot detachable box magazine. Sights consisted of tangent leaf with graduations for 25-100 meters and a tube enclosed front sight with 5 interchangable posts.
The A6 was a cheaper model, with no checkering on the stock and a fixed blade for a front sight and a leaf and elevator rear sight.
The A7 had similar sights to A3, but no checkering on pistol grip. It also fired from a closed bolt.
The E series are takedown models with a two piece stock, and a flat sided, round back receiver, rather than the round tubular style receiver of the A series guns. Barrel was 19.3” long.
