A high-quality kit from the Italian company Megaline.
Cleaning a gun is a serious matter - it prolongs its life and helps preserve its original technical parameters for a longer period of time. Lack of cleaning results in the deposition of filings in the barrel, which leads to the loss of initial velocity of the bullet and even to permanent damage to the barrel.
Only brass cleaning notches clean the gun properly - metal ones, on the other hand, corrode and cause the opposite effect (moreover, they have a hardness of steel similar to that of the barrel and scratch it). Plastic cutters instead of cleaning the barrel - they get dirty - they rub against the threads (on the principle of a grater) - leaving fine filings.
