SubscribeCopper deposits in gun barrels have always been a problem. In the past, copper deposits were removed by maintainers for example though flooding of the interior of the barrel with a solution of water and acid.
The process proved to be time consuming, hazardous to personnel and of great concern to the environment.
The Milfoam bore cleaning foam has been proven effective for cleaning corrosive combustion residue of various types of military ammunition. The bore cleaning foam is easy to use and thus it has reduced the time and labour needed for weapon maintenance.
As a result of two to five treatments, barrels of a 23 mm (barrel length 1700 mm.) and a 30 mm (barrel length 1080 mm.) were cleaned to meet the standards. The number of treatments was related to the length and rather excessive copper residue in these barrels. Our experience is that this copper cleaning foam is among the best products available, it is easy to use and it cleans barrels effectively.
The new mechanical bore cleaning foam dispensing system (NSN1015-20-001-7605) available from Milfoam Ltd not only addresses time and safety issues, it offers the operator independence because now the operator can keep the barrel in optimum condition. Routinely cleaning with de-coppering agent ensures the reliable predictable muzzle velocity measurements. By itself the foam is non-toxic and therefore the only remaining hazard is the combination of propellant residue and metal deposits absorbed by the cleaning foam, which is easily absorbed by rags.
Eight 5 inch 54 caliber gun barrels were cleaned by the Milfoam system and inspected. An earlier inspection had shown that there was propellant residue, rust and copper deposits throughout the bore and chamber areas. In order to determine that the barrels were in serviceable condition it was imperative to clean the barrels to the extent that the inspector could be able to visually see the bore and chamber surfaces and collect accurate internal measurements. The Milfoam Cleaning System was selected as the most ideal system to accomplish this task. The Milfoam system was programmed to clean overnight while unattended as well as during the daytime hours. The barrels were thoroughly cleaned to the satisfaction of the inspector.
