The best way to clean your polymer AR15 lower is to take it apart and clean every piece individually. Make sure to use a gentle cleaning solvent and a soft cloth to avoid scratching the surface. You can also use a brush to remove any built-up dirt or debris. Reassemble the lower once it’s clean and apply a light coat of oil to help keep it in good condition.
When it comes to gun cleaning, there is no one-size-fits-all solution. The best way to clean your AR15 lower will vary depending on the materials it’s made from and how often you use it. However, taking the time to disassemble and clean each piece individually will help ensure that your lower stays in good condition for years to come.
