Airsoft Megastore Custom Built AEGs:
The benefit of buying an Airsoft Megastore custom AEG is not only that every component is handpicked by our expert staff for compatibility and functionality, but you also save money when you buy a custom gun rather than purchasing all the parts individually to build it yourself.  The best part of buying an Airsoft Megastore custom gun is that you no longer have to worry about which part will work with your AEG.  The entire airsoft rifle ships out with the parts and accessories pre-installed!

Our take:  The Airsoft Megastore Custom JG M4 Olympic Arms RIS CQB Airsoft AEG is the perfect for both fast paced CQB and field type games.  Externally, this custom M4 features a polymer body for lightweight construction, and a full metal Olympic Arms quad rail system.  The original front sight has been swapped out for an APS flip up front sight, which makes mounting optics easier than ever.  Internally, this custom AEG features the high quality Version 2 reinforced gearbox from JG and has excellent accuracy and range.  This is the perfect airsoft rifle for any player looking to purchase a new tactical CQB / field style AEG.

NOTE:  All parts have been preinstalled onto this custom airsoft rifle.

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 also automatically shut off once the battery is fully charged to avoid overcharged batteries.

5 Airsoft Megastore Custom JG M4 Olympic Arms RIS CQB AEG Rifle *****
Simply Amazing

"I use this weapon as my main with my normal load out. I have a very high K/D with it so far due to how accurate it is. No problems I can think of, and nothing has broken on or in it yet. I mounted a new scope on top and rigged up a new sling, along with a light. You need 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
