دانلود کتاب AR-15/M16 super systems

I recieved this book as a gift from a relative who meant well, but was not very gun savvy...This book sufers from the 'need to put out another title syndrome.' In effect, nothing in this book is of value- the modifications are flights of fancy or hack job work. Basic searching on the internet will teach you more about building or upgrading the AR-15 platform than this book. Additionally, it is rife with inaccuracies and/or bad techniques to do modifications to the AR-15.Morevover, this book is at least a decade and a half out of date. Many of the companies listed as parts sources (Rhino Systems for example) have been out of business for a decade, and it doesn't even address the A3 flattop configuartion that is the standard these days. It is obvious that the book is just a reprint of something from circa 1987 with no re-editing ro re-writing.Finally, many of the chapters just read as one big advertisement for this company or that product, much like the current articles in many gun magazines. It is obvious Duncan Long gave glowing reviews of products in exchange for free samples of those products.In short, this book is a waste of money. If not for the fact it was a present I would probably toss it out. If you want to learn about the AR-15 there are many far better sources in print and on the web.
