Courtesy of the National Shooting Sports Foundation (NSSF), Gunsite Instructor Cory Trapp goes through AR-15 disassembly, cleaning, maintenance and inspection.

This is one of the better videos I’ve seen on this subject, especially how Trapp dispells several AR-15 myths related to lubrication and reliability.

He covers:

  • AR-15 disassembly and reassembly
  • Why the .223 and 5.56 are not interchangeable
  • AR-15 feedramps: Standard M16 vs. M4 styles
  • AR-15 Bolt disassembly and maintenance tips
  • Trigger group cleaning (what not to do)
  • How to replace the extractor spring
  • Spare parts you need on hand for your AR-15
  • How to properly reassemble the bolt assembly
  • Why you should not lubricate your lower or the buffer
  • What to look for when doing an inspection
  • The AR function check you should do each time you reassemble your AR
