Did you know?💡 Every gun shipped by FN Herstal has been individually test-fired.
There is a saying: “The proof of the pudding is in the eating.”🍮 You can follow the recipe and still end up with something that looks fine, but to be sure, you must taste it, and sometimes the result is disappointing.
In FN materials, parts and assemblies are constantly inspected and gauged at every stage of manufacturing to ensure conformity. Before final assembly, parts that withstand the pressure created by firing are tested at the independent Liège Proof House, firing two cartridges with 25% more pressure than the maximum level authorized for production ammunition. This legal requirement dates back to 1672 (not a misprint 🤯). After complete assembly, the guns are inspected, lubricated, and sent to indoor ranges attached to the assembly line.
The Delivery and Acceptance Specifications, which are part of the contract with the customer, include the procedure for firing tests and the results to be achieved. For a simple weapon like a pistol, this will be functioning and accuracy; for a machine gun, there are more tests and adjustments such as the rate of fire and functioning with a weight hanging from the belt. The procedure for each type of weapon is adapted to the essential functions to be checked. On average, a weapon fires about 30 rounds. If the weapon fails the test, it goes back to the assembly line to be corrected, then it’s retested . After firing, the guns are cleaned, inspected again, oiled, and packed for shipping. 👨🏭🔁
On large batches, a customer may send a team to select weapons at random and witness a re-test. A Belgian army representative is based in the factory to check all quality control procedures for Belgian government contracts, and as part of NATO’s arrangements, he also provides this service to other members. 🇧🇪📦
Although FN Herstal typically uses its own ammunition for testing, special cases arise. For certain clients, testing may be conducted with non-standard ammunition.
All the quality control procedures during the production process culminate with the final firing test, which ensures that customers receive fully functional weapons.
The proof of the gun is in the shooting. 💨
