Battery Charger Recommendation: Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery (overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly). Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly, also automatically shut off once the battery is fully charged to avoid overcharged batteries.

Great gun!!

"Great gun for the price, I put an 11.1v Lipo on it and it tears the field up and the look of the gun is an exact duplicate of it's real counterpart its very lightweight...and best part is its ready to go out of the box no extra battery required 8)"

pretty Good

"Overall this is a great gun. FPS is roughly 385. Pros: length of gun very accurate good rate of fire Keymod rail system. Cons: Iron sight Fake ambi the butt of the stock falls off easily. Overall internally this gun is a beast externally is good but a little on the fragile side."

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
