The National Shooting Sports Foundation has released another of their Sportcasts. This one features Gunsite instructor and gunsmith Cory Trapp discussing how to clean and maintain your AR-15.
This video is as good, if not better, than many of the $19.99 or $29.99 commercial DVDs showing you the same information. I’d suggest bookmarking this one as you’ll want to watch parts of it over and over as a reference.
Very nicely done.
