5 CYMA M4 RIS Full Metal Gearbox Airsoft AEG Rifle - X-Tac Polymer *****
Philip Lutz III

"This gun is absolutely amazing. Says it shoots 40 to 50 meters on the box, I think it does more. Hard hitting, battery on mine has lasted for a week (hour a day use or so) and I could not have asked for a better primary. HIGHLY RECOMMEND"

Great Gun!

"For starters it is a great gun. Hard Hitting, Accurate, and has the real weight of a m4. Gearbox works smoothly, No jams, Hop up works great. My only problem with it is that about a week after receiving it, it started shooting wrong. At first I thought it was a gearbox problem but after contacting customer service it turned out that it had run out of "oil". After cleaning the barrel and spraying silicon oil into the loading dock the gun worked just fine. I would suggest this gun to anybody looking for a quality beginner or intermediate gun."

CYMA M4 RIS Xtac polymer

"Spectacular AEG. Do not waste your money on a so called "high end" airsoft guns. I've been successful in firefights against KWAs and even Polarstars with this AEG. This airsoft gun has incredible range and firepower, and the polymer is extremely durable. In the buildings or on the field, this airsoft gun is the right buy for anyone. "

This is a amazing gun

"The guns looks amazing and the rails make it possible to customize the gun a whole lot. The carrying handle/sight is removable and a great place to put a Scope. The FPS is nice and the accuracy is great. I think this is a great gun for beginners and pro players too."

Great gun

"This think shoots great out of the box and it feels realistic. Also it has rails and a nice crane stock all under 150. It's great to upgrade and to use as a backup just as it is."

Good to Start

"Great weapon for the new airsoft gamer. It delivers a light weight and durable weapon platform ready to accept many attachments. It shoots very well out of the box. I would suggest upgrading the hop up to a metal one though as the hop up broke in mine in the 3rd day of gaming with it. I also is not very compatible with other rail systems or m4 bodies. they have their own barrel/delta ring mounting system. It's very strange to me. If you're looking to get into airsoft and looking for a cheap option that will have you up to par with the local players look no further!"

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
