Otis 5.56 buttstock cleaning kit
This is the cleaning kit you might want to consider throwing in your butt stock if you can fit one in there. The tools that this gun cleaning kit comes with should get the job done after long firing sessions. One thing to consider is that gun cleaning sometimes is over done and you can damage a firearm with too much scraping and cleaning. I have never seen it happen, but I have read several articles in SWAT magazine that referred to people over cleaning AR15 guns.
Cleaning out the chamber is not as important as keep a DI AR15 lubricated, but I have never been one to leave a gun sit un cleaned for more than a week. The Otis gun cleaning system are well thought out gun cleaning kits that have the brushes and attachments to cleaning various parts of a firearm. The Otis 5.56 butt stock cleaning kit is even more practical because it fits inside the gun and doesn’t need to be hauled around in a range bag. Having an Otis kit will probable reduce your need on packing gun cleaning supplies in another bag.
