Today's high-performance artillery requires regular cleaning and decoppering to ensure maximum performance and operational readiness as measured, for example by less dispersion in muzzle velocity (MV). The strenuous labor associated with barrel cleaning can now be replaced with a quick, easy, and more efficient process.

The MG7155 System kit drastically reduces the time, cost and inconvenience of cleaning and decoppering. It also removes propellant residues in an environmentally safe manner.

Now, cleaning and decoppering can be performed in the field using a simple procedure that does not require special training or tools. All that is required is a MG7155 System kit that is comprised of a patented MG7155 dispenser and MG7100 D-COP foam.

The MG7100 D-COP foam removes copper, brass and combustion wastes, yet contains no corrosive agents. The result is a breakthrough in gun bore cleaning and decoppering.


  • It ensures complete and precise foam application, at the required thickness for consistent and complete cleaning and decoppering
  • The entire process can be performed in less than an hour on 155mm caliber bores from start to finish
  • The gun can be put in service even during cleaning process, if necessary
  • The foam residue can be completely and safely disposed
  • It is designed for simple field application with no gun disassembly required
  • Militarized carrying case with all accessories included for ease of transportation
