I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
Best Site for Airsofting Gear and Guns
