solid first gun

"The gun is very nice it is a sterdy metal receiver it has good polymer furniture but the front sight is non removable so you will have to get high mounting rings for your optic of choice other than that i recommend this gun"

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
