5 JG 450rd M4 / M16 Airsoft Extended High Capacity Magazine *****
Excellent Choice

"I purchased five of these over a year ago and have used them at skirmishes or ops on an almost weekly basis. My son and I have used these with various M4s (Ares, TM, JG, G&G), DE 416, G&G FN2000 and the PTS Masada without problem. The outer shell is high quality metal and have yet to see one crack or break. On the internals, I have not yet been forced to take one apart to fix an internal problem or jam. The only issue - and I don't blame the magazines - it that I jammed one into a KWA M4 and it apparently pinched the mag, as it now does not seat tightly in my Ares M4. For the person who commented on the JG - these were a tight fit, but they fit. Before you spend much, much more on the 600 round Surefire "fat mag" replicas; consider buying a couple of these 450 to 500 round mags. "

Hey Braden!

"A good way for you to find mags for your gun it to go to the web page that it's selled on (on this website) and look in the extra mags section and it will give you a selection of mags that will fit your gun. Hope this helped you."

Terrible

"I got 2 of these for my JG M4 S-system. They were a tight fit from the beginning, and got progressively worse. The first one broke when I lent it to a friend during a war who has an AMS SRC Stryke M4. He had to jam it in, and when he pulled it out, only the outer shell came. All the internals stayed in the mag well, and we had to wrestle it out. The second one broke in the middle of a war. It simply stopped feeding. Coincidentally, this was right when my 1911 ran out of C02. Another problem with these are the winding gears move inward after a few uses. Trying to wind them with my bare hand was hard enough, and near impossible with gloves on. Overall a bad buy. (And don't be under the impression that all JG Mags are bad. The 300 rounders work perfectly)"

"Junk. Used about 3 times and it started to jam. Opened it up and 3 teeth were missing from the feed gear."

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
Every time I purchase from Airsoft Megastore I am very satisfied with my order. It arrives on time and the deals are excellent. AMS is probably my go to place for airsofting equipment, especially when I'm itching to add another gun to my collection! macawilliams12, USA
