Frequently Asked Questions

What is the minimum maintenance required for an AR-15 that hasn't been used recently?

At a minimum, apply a light coat of CLP or oil to the metal-on-metal parts of your AR-15. This includes the Bolt Carrier Group (BCG) and charging handle components, as well as the inside of the upper receiver's charging handle channel.

How should I lubricate the charging handle on my AR-15?

When lubricating the charging handle, apply oil to its components but avoid the gripping surfaces. This prevents the handle from smacking your face during operation, ensuring a smoother shooting experience.

What is the brown, sticky substance found on new AR-15s?

The brown, sticky substance often found on new, off-the-shelf AR-15s is typically cosmoline, a rust preventative. It can be effectively removed using a rag with a little heat, light CLP, or a suitable solvent.

Should I lubricate the buffer spring and buffer on my AR-15?

Yes, your AR-15's buffer spring and buffer should already have grease on them from the manufacturer or when it was built. Ensure this grease is present as part of your maintenance routine.
