Type of Finish: Black gun paint & oil darkened metal

Finish Originality: Original

Bore Condition: The bore is bright and the rifling is sharp. There is light to moderate erosion in the bore.

In this writer’s opinion, this bore rates 6.5 out of 10.

Many military and C&R eligible weapons have bores that will show erosion. This is not only due to age but to the fact that corrosive primers were commonly used in ammunition worldwide. For example, the U.S. used corrosive ammunition throughout WWII. The U.S. military did not begin to phase out corrosive-primed ammunition until the 1950s.

Overall Condition: This rifle retains about 70% of its metal finish. There are scuffs and scratches throughout the metal surfaces. The black paint is worn on the receiver, the barrel exterior, bayonet lug, the nose cap & gas block, and trigger guard assembly. There is heavy wear to the finish at the front right side of the receiver and the charger clip guides. There is oxidation on the barrel band. There is wear to the finish on the magazine release, inside the magwell, and on the charging handle. The magazine has heavy wear to the black paint finish along the bottom. The screw heads show moderate use. The markings are mostly clear though the crest and the front right side serial number are worn. Overall, this rifle rates in about Good condition.

Mechanics: The action functions correctly. We did not fire this rifle. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance requirements.

Box, Paperwork & Accessories: This rifle comes with a cut-down 10 round magazine.

Our Assessment: Argentina was one of the many countries that contracted FN49 rifles from Fabrique Nationale Herstal. The contract was for around 5,500 rifles in the Argentine 7.65x53mm cartridge, which were to be issued to the Argentine Navy. This contract was completed in the mid 1950s. It was around this time that the Argentine military adopted the FAL in chambered in 7.62×51 NATO, also from FNH. It was determined in the late 1960s to update and rechamber the FN49s in the Argentine inventory to have them fit better into the logistics network. Nearly all of the FN49s were converted domestically to 7.62×51 NATO by Metalúrgica Centro. The fixed 10 round magazines were also removed in favor of detachable 20 round box magazines. These would see limited use during the Falklands War. Upon being surplused into the United States, some of the 20 round magazines were crudely cut down to 10 rounds. This example has matching serial numbers on the serialized parts. The magazine has been cut down to 10 rounds. The stock has wear throughout, with a small crack on the left side near the receiver ring. Some of the black paint finish remains, with much of it having been worn from the receiver, barrel exterior, and trigger guard assembly. There is also heavy wear along the right side of the charger clip guides. The bore is bright with strong rifling and light to moderate erosion. Atypically, these conversions were well done and the rifles tend to perform well with modern 7.62×51 NATO ammunition. This would fit into any Argentine, South American, FN49, or FNH collection.
