If you own an AR-15 you may have had a similar thought process: “Hmmmmmmm…. why is my AR-15 jamming/malfunctioning all of a sudden?”. I recently had an AR-15 start misfiring (light strikes) and after considering the primers I had loaded with and other factors I decided to disassemble, clean and lubricate the Bolt Carrier Group (BCG). Well, after that my AR-15 was running perfectly. The point is: before you start blaming your AR-15 or ammunition for reliability issues, give your gun a good cleaning!
Recently on the Accurate Shooter Daily Bulletin, Paul’s team published a great BCG maintenance overview with a ton of links to great info on the topic from the Top Quark Blog.
If you are needing a refresher (or first time guide) on how to work on your BCG, you should check out this great blog post. I’ve also posted some tech info on the assembly and disassembly of the standard AR-15 BCG during the AR-MPR rifle build project right here on Ultimate Reloader. Here’s a link to that post, and the corresponding video:
This will be one of my projects coming up this weekend- another BCG maintenance session. Should be fun!
Safe shooting, and keep those AR-15’s tuned up!
