I was wondering if there is a book that covers the fine tuning of AR rifles to ensure flawless operation. I noticed when shooting my 6x45 that there are some swipe marks on the neck on some of the brass but not on all of it and I know you guys (Rich and Greg) know a lot about this stuff but I was just wondering if there is some book out there that I could read so I really understand the internal workings and the cause and effect of different things within the gun. Thank you Brian
Swipes are technically limited to the case head from the ejector having brass flow into the hole and the action opening early before the pressure drops.
If you mean scratches on the neck you can go in and break the sharp edges on the back of the locking area. This will cut down on scrapes. Also you see the bullet scratches when you extract the loaded manually because the case starts to twist sideways because of the ejector and extractor working in concert.
For case mouth dents you can put a 5/8"square of sticky backed Velcro on the shell deflector.
Books for how it runs. I have read Sweeneys book and those by Zeideker. Scott Duff has a very well respected book out also. I like Zeideker because he gets into nuts and bolts assuming a modicum of basic knowledge.
There are probably less than a dozen things that keeps an AR from running. If it gets gas then it comes down to extractors/ejectord. The ammo has to be the right size with appropriate powders. Pretty straightforward if you take a systematic approach.
Oh, and the phone is always handy.

The best firearm for self defense? Any loaded one will do.
