AR owners know that their black rifles require regular cleaning and maintenance. And this modular platform allows many options for stocks, fore-arms, and optics mounting. That ability to customize is one of the AR’s major attractions, but customization requires solid understanding of the AR’s design and components.

To help AR owners optimize their rifles and maintain their rifles properly, Gun Digest Media publisihes a 320-page illustrated book: AR-15 Setup, Maintenance and Repair. Authored by Patrick Sweeney, this book is a “one-stop guide to repairing, maintaining and modifying America’s favorite rifle.” The current publisher price for the book is $29.50 from Gun Digest, but it is available “used like new” on Amazon for $24.15* in paperback. Digital editions are offered by GunDigest for $27.99.

Note, if you are interested in the book, there is a substantial 40+ page FREE sample available on the Amazon site. You can see the entirety of the first two chapters from the Kindle digital version.

AR Set-Up and Maintenance
If you need to disassemble and maintain your AR rifle, swap barrels or handguards, add optics, or customize the stock, Gun Digest’s AR-15 Setup, Maintenance and Repair book tells you what you need to know. From field-stripping to barrel mounting and trigger installations, the book covers a wide range of topics. The book provides step-by-step instructions for set-up and maintenance, with hundreds of detailed photos. The book also includes AR gunsmithing chapters with reviews of recommended tools.

Author Patrick Sweeney is a certified master gunsmith and armorer instructor for police departments. Sweeney has also authored the notable 4-volume Gunsmithing the AR-15 series (Vol. 1, Vol. 2, Vol. 3, and Vol. 4) and 20+ other titles for Gun Digest Books.

Whether you want to learn about disassembling your AR for regular maintenance, field-stripping, swapping out parts, adding optics or customizing a stock, AR-15 Setup, Maintenance and Repair guides you through everything you need to know to keep your AR-platform rifle running well. There are also tips on how to improve accuracy, and maintain your bolt carrier group properly.

Editor’s NOTE: The key to keeping an AR running reliably is proper lubrication (in the RIGHT places), and regular cleaning of the bolt carrier and bolt, including ejector recess and extractor recess. The majority of non-functioning ARs we’ve seen had gunk, lube, carbon, and brass shavings in those recesses.
