Product Description
2010 revision - Before upgrading an AEG, it is suggested that you first define your upgrade objective(s). What do you want to achieve? High FPS? High ROF? High accuracy? And how high is high by the way? The 2010 MAJOR UPDATE book is organized based on the primary upgrade objectives of high FPS, high ROF and high accuracy. In addition, a section on troubleshooting is included. We tell you what to do and what to avoid so you can achieve the best possible performance without spending all your savings. And we do not simply assume you have a particular model from a particular manufacturer. The extensiveness of the brands and mechanisms covered allows you to apply your know-hows towards almost all AEGs in the market. An easy-to-read Q&A format backed up with annotated photographs and diagrams whenever necessary would make this a valuable read. LATEST REVISION ALSO INCLUDES MODEL SPECIFIC COVERAGE ON M4, MP5, G36, G3 and AK.

Before upgrading an AEG, it is suggested that you first define your upgrade objective(s). What do you want to achieve? High FPS? High ROF? High accuracy? And how high is high by the way? The e-book is organized based on the primary upgrade objectives of high FPS, high ROF and high accuracy. In addition, a section on troubleshooting is included.
We tell you what to do and what to avoid so you can achieve the best possible performance without spending all your savings. And we do not simply assume you have a particular model from a particular manufacturer.
The extensiveness of the brands and mechanisms covered allows you to apply your know-hows towards almost all AEGs (including the latest low cost entries such as the SRCs and the UTGs) in the market.
Rather than going the cumbersome step-by-step way, we teach you the essentials through an easy-to-read Q&A format backed up with annotated photographs and diagrams whenever necessary.
This title is model independent. The information and knowledge provided can be applied to all full blown AEGs (TM, ICS, CA, ACX, SRC, UTG, Cybergun, JC, CYMA and others) in the market. The new MP7 type of SMG AEGs are briefly covered as well.
With over 180 pages of text and illustrations, this book is a MUST READ if you want to master the art of AEG upgrade and optimization!

 Easy Read October 8, 2009

This book is was an easy read. I would suggest it to a friend. I did find that the author was bias towards TM airsoft guns and some what disliked Chinese clones. Also he barely touched MOSFET modifications. This book is good if you use a lot of Internet websites and you tube videos as further references. It does give a nice grasp on what each modification will do to improve your guns performance. When I mentioned I was getting this book on an airsoft forum someone replied with, "books are a waste of time and money". I strongly disagree with this person and if you even gain one bit of usefully information from this book that alone is worth the price. I'm giving it a 4 out of 5 because,
Pros:
It gives a beginner a nice starting point on the mechanics on how an airsoft gun works and what parts are important.
Very fast and easy read where you will not loss interest or feel intimidated by what the author is trying to explain
Good guide lines on how to start your upgrade project and what parts should also be upgraded if you plan on changing a certain part. An example is the spring.
Nice illustration and pictures explaining parts.
Cons:
Author was bias about TM compared to Chinese clones. I feel their are a lot of nice clones out in the market, one being Dboys. If it was not for the affordable price of these guns I would not have gotten into the sport and know a lot of others that share the same feeling. I would have also not had the extra cash to spend 29.99 on a book.
For some players 29.99 might be a bit high for a book.

Federal Law mandates that all airsoft guns are sold with a 1/3" orange tip. It is illegal to remove this orange tip,
and this removal will void any warranty. In order to purchase any airsoft gun you must be 18 years or older.
Please act responsibly with your airsoft gun.
