I highly recommend this to anyone that has an interest in upgrading their current weapon and/or want to start a new project.
Practical AEG Upgrade: Methods, Tricks, & Myths 09'
http://www.amazon.com/Practical-AEG-Upg ... 440424896/
The English is a little poor is some ares and the flow of the pages is a little off sometimes, but overall it is a great beginners book.
It will assist in making better informed decisions and questions.
Has anyone else checked out any other products by Airsoft Press?
As a side note the e-book version are considerably cheaper.
