Essential Cleaning Kit
| Item | Purpose | Recommended |

The AR-15 Runs Wet
The AR-15 direct impingement system blows carbon into the bolt carrier group. The platform is designed to run with generous lubrication. A wet AR-15 keeps running when dirty; a dry AR-15 stops much sooner.
Where to Lubricate
- Bolt carrier rails (heavy)
- Cam pin (medium)
- Bolt lugs and tail (medium)
- Charging handle channel (light)
- Trigger pins (drop only)
Cleaning Frequency
| Situation | Frequency |
|---|---|
| After range session | Recommended |
| Every 500 rounds | Minimum |
| Home defense (unfired) | Monthly inspection |
| Corrosive ammo | Immediately |
What NOT to Use
- WD-40: Not a gun lubricant, attracts dust
- Motor oil: Wrong viscosity
- Miracle solvents at 3x price: Standard solvents work fine
