Introduced in 1949, this rifle was converted to 7.62mm for use by the Argentine Navy. Standard blade and tangent peep sights, with the Argentine crest and boxed "ARA" stamp on the receiver ring, FN address on the left side of the receiver, and matching numbers on the receiver, bolt, and smooth pistol grip stock with a leather sling.

Very good as Arsenal refurbished at the time of conversion, with 98% of the current blue, showing mild handling marks and edge wear. Stock is very good, with a thin crack forming on top of the wrist and some pressure dents. Mechanically very good.
