The Portuguese G3 is a rifle length battle rifle based on the H&K roller locking G3 rifle. It features a green polymer fixed stock set, and a select fire trigger box, this particular rifle is a factory built semi-auto import, which is why the trigger box is only semi-auto. The G3 was adopted in the early 1960's by the German military. The G3 was a technically updated version of the CETME-C rifle, and the Portuguese military adopted the G3 and started producing it under license in 1962. The G3 has a 450mm barrel and a stamped sheet metal receiver.

 

The Portuguese G3 can be identified by several markings on the firearm. On the left side of the firearm on the receiver, near the magwell there is a "FMP" marking, identifying it as Portuguese made. The receiver also shows the model name, year of manufacture, and serial number. In addition, "FMP" markings can be found on the barrel, bolt carrier group, and magazines. Matching numbers for the rifle can be spotted as well on the trigger pack, on the left side, on the metal buttstock ferrule, and bolt and carrier.

 

The Portuguese G3 is a licensed contract made firearm, and as such has the same design features as an H&K G3.

 

The Portuguese G3 operates with a manual of arms comparable to a standard G3 battle rifle.
