JG UA-3 RAS Full Metal Gearbox Airsoft AEG Rifle w/ Metal RIS

Perhaps one of the most surprising new airsoft AEGs yet, the all-new enhanced JG Urban Assault UA-3 RAS is a good sign of what's to come in the world of airsoft from the likes of JG & Co., as they put out an ultra powerful, ultra versatile airsoft AEG outfitted with the most reinforced internals/powerful motor set-up in a stock airsoft AEG yet. The Urban Assault UA-3 RAS is a unique yet powerful airsoft AEG that beats out rivals costing more than TWICE as much, and is perhaps your best bet for a metal gearbox Urban Assault UA-3 RAS with a rail system for under $400. With a muzzle velocity that easily outpowers Tokyo Marui, CA, or ICS AEGs, this rifle is ready to rock and roll.

New for this year is the addition of a MOSFET CHIP pre-wired into the rifle's circuitry and a reinforced ultra high-torque motor, bringing increased power,rate of fire, and more overall electronic stability to this ultrahigh-performance Airsoft AEG. Also, the fully integrated one-piece rail system has been slightly refitted to better work with the unit's new tighter-bored barrel, which enables this beast of an Airsoft gun to gain staggering performance numbers, as it tops out at close to 450FPS.

The AEG comes standard with a 8.4v battery, which is equally impressive as it is capable of firing over 800+ rounds per minute on a full charge.


Performance regulator chip, to ensure all systems are in the green(controls variables like heat and voltage to ensure the highest rate of fire even under the most strenuous conditions)

High performance MOSFET aids in power delivery, meaning quicker trigger response and longer battery life

Previously available only on CUSTOM airsoft guns costing lots more money, the MOSFET is a standard feature on the all-new JG Urban Assault UA-3 RAS

Lowest price on the market for a MOSFET-equipped airsoft M4 S-System AEG, only at Airsoft Megastore!

With its full metal RAS rail system, this JG Urban Assault UA-3 RAS offers top value for your dollar in terms of versatility, as any number of scope, laser/light, launcher, and other customization upgrades can be easily done simply by attaching the parts onto the rail system. Because it is compatible with Tokyo Marui parts and many other aftermarket upgrade parts, it can be easily customized and upgraded.

QUALITY ASSURANCE: Through numerous factory visits, we are able to confirm that JG tests EACH and EVERY single AEG that they ship out by putting each unit through a rigorous 16-point inspection, which ends with a Q.C. agent shooting no less than 450 rounds from the rifle to ensure quality before exiting the factory (hence sometimes buyers may find a BB or two left in their mag, as a result of the Quality Control agent's test firing). This gives us even more confidence that JG is ever-increasing their attention paid to quality, and is a contributing reason to why the quality of JG AEGs gets better year after year.

Ammo type: Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs. For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs which carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

Battery Charger Recommendation: Although this fully automatic airsoft rifle comes with a standard wall charger to charge the battery, 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.
