Common Mistakes To Avoid When Cleaning A Flash Suppressor

Explanation Of The Common Mistakes Made During The Cleaning Process

Cleaning a firearm’s flash suppressor is vital for the gun’s optimal performance, but it’s not uncommon for gun enthusiasts to make mistakes during the cleaning process. Below are some of the very common errors to avoid:

  • Overusing solvents: Using too much solvent when cleaning your flash suppressor can not only damage the gun’s finish but also malfunction and make it less effective. Solvents can dissolve the glue that holds the flash suppressor or coating layers in place, affecting its accuracy. Therefore, you should use a minimal quantity of solvent while cleaning your firearm.
  • Using a brush aggressively: Various cleaning materials are available in the market, such as nylon brushes, steel brushes, and copper brushes. Using a brush that is too aggressive during cleaning can damage the suppressor’s finish. A damaged finish can accumulate deposits, dirt, and debris, eventually leading to an obstructed suppressor. You should use only a nylon brush that matches the bore size of your firearm.
  • Not disassembling the flash suppressor: Disassembling the flash suppressor while cleaning may be time-consuming, but it is essential to ensure a thorough cleaning process. Not disassembling the suppressor increases the risk of damaging it and also reduces its lifespan.

How To Avoid These Mistakes And Ensure That The Cleaning Is Done Correctly
