A device, typically constructed from metal, designed to be affixed to the end of a firearm barrel and intended to capture cleaning solvents and debris. The primary function is to prevent these materials from being expelled into the environment during the cleaning process. These systems often feature a series of internal baffles or chambers to efficiently collect the cleaning fluids and residue.
The use of such a mechanism offers several advantages, including environmental protection by containing potentially harmful chemicals. Additionally, it contributes to maintaining a cleaner workspace, reducing the risk of contamination or spillage. The concept behind this method aligns with responsible firearm maintenance practices and promotes a more sustainable approach to gun cleaning. Historically, makeshift solutions were employed for similar purposes; however, modern iterations offer enhanced efficiency and ease of use.
