QUANTITY

Our take:  The all-new enhanced JG Urban Assault UA-4 HYBRID RAS is the hottest and most highly-anticipated new arrival from JG, and Airsoft Megastore is the first in the nation to have it in stock and ready to ship at a rock-bottom price.  Perhaps one of the most intriguing new Airsoft AEGs to come from JG, the UA-4 HYBRID RAS fully automatic electric AEG rifle is a near-perfect rendition of the highly versatile BULLPUP rifle platform.

Outfitted with a newly redesigned high performance full metal gearbox, which is coupled with JG's enhanced ultra high-torque motor, the Urban Assault HYBRID RAS rifle shoots smoothly at OVER 400 FPS.  Accuracy is equally amazing, as you can accurately take down targets at over 100 feet.  This is due in no small part to the high performance internals AND the carbine-length barrel, which greatly increases power and accuracy due to its strategic application in a Bullpup-style rifle such as the UA-4.

A fully integrated rail system comes standard with the rifle, making it a modular platform that you can easily attach all sorts of accessories to (i.e. laser sighting units, scopes/sights, flashlights, etc.)

New for this year is the addition of an ultra high-torque motor customized by JG,bringing increased power, rate of fire, and more overall performance stability to this ultra high-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 over 400 FPS in muzzle velocity.

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.

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.

Specifications:
Operation:  Electric Automatic
Build:  Metal gearbox / Polymer receiver
Firing Modes:  Semi-automatic and Full-automatic
Muzzle Velocity:  380-430 FPS
Magazine:  300-round high capacity (gear wind-up)
Gearbox:  Full metal reinforced
Battery Type:  8.4V Mini
Inner Barrel Length:  509 mm
Hop-up:  Adjustable
Weight:  8 pounds

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.

Package includes:  Rifle, rechargeable battery, wall charger, instruction manual, 300-round high capacity magazine

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.

By: Chris

"at first i could not get the gun to respond. I put a fully charged and functional battery in it and got nothing. so i oppened up the fuse case, took out the fuse and connected thewires and found that a bad fuse was the problem..... got a new fuse and now it works geat. deffinetly put silicone spray on the bolt and down the barrel to loosen and greese it up. the hop up works very well.... the gun is very accurate, and can reach up to 40 -60 yards and has an fps of about 380 with .20's.... gun looks and feels awesome and i suggest you put a grip and sight on it, overall a great gun by jg and thanks ams for helping with the fuse problem."

Very good gun had it for almost a year!
09/04/13
By: jonathan

"I have had this gun for pretty close to a year it has shot great! out shot all of my friends shoots about 315-330 fps with .20g bbs. scopes work great on the gun because of it long range. i have accurately hit a target at 300 ft! this gun has great fire rate and clip size! clips are cheap but do not brake easy. all together this gun is a champ, i think i am going to upgrade it with better gears and piston set along with a new higher torque moter. Warning!! Make sure you use high grade bbs with the long barrel and lube it with silicone spray after about 5,000-7,000 rounds are fired! All in all a great stock gun GREAT BUY!"

"This is an epic gun for pro players and even newbs. It has the best performance that ive ever seen and the battery lasts forever. Most of it is full metal and then the back part is abs plastic. I took this in a war yesterday and army crawled through a lot of nasty stuff and it withstood it all. This is a great gun for the price."

By: Matt

"1. The sights are plastic junk so aim over the rail or buy a scope. 2. There are NO feeding issues with the JG AUG A3 (I know I have owned one for a year now) and yes it is the same gun with a different rail system."

UA-4 (Ultimate Awesomeness- 4)
15/01/12
By: GB Nash

"I will be using this gun in an upcoming airsoft war and after test firing it's rate of fire and accuracy puts my other machine guns to shame. This gun is outstanding and if possible I would get a nice sight and a foregrip for it and it makes this astounding gun even deadlier."

Great gun
04/11/11
By: Ryan Green

"this gun is great. its easy to handle, has a good weight, and a lot of space for attachments. i have a red dot sight on mine and it works great. the range is outstanding although the rate of fire is low. im not sure if you could fit a 9.6v in the battery space, its a small compartment. it competes with my 450 fps mp5, and my friend's f2000 and my other friend's ACR. if you are thinking about this gun, i would recommend it.

Love this AUG
25/09/11
By: Cavenut

"This is a very good AEG. Great look, great fire power. I've been using it for several months now and have been very happy. As everyone states, trash the sites that come with it and just get a scope right away. I did replace the air nozzle, hop up, and changed to a metal spring guide (crappy plastic one inside). Not because I had to but because.... Yea because. It now shoots 400 FPS with .20's This is a great weapon to have as part of your arsenal. If I had anything bad to say it would be the clips. Largest one available is 330 and I've had two fail already. I have fixed them (broken spring) but its just a pain to have to do that. So, gun good, clip bad."

JG AU-4G AEG - An Excellent Choice
24/09/11
By: Michael

"I just got this gun in the mail and set up some targeting for myself to try it out. I have to say I'm really impressed with the out of the box performance of this gun. Accuracy and groupings are nice and tight and the rate of fire is very impressive. The build quality of this gun is about half metal half plastic which is probably a good thing since it's already a bit heavy. It's well balanced feels durable to hold. I can't wait to get this out to the airsoft field. Pros: High ROF, great accuracy and groupings, two stage trigger, good FPS, nice RIS , nice design, functional charging handle exposes hop-up unit. Cons: Throw the included sights in the garbage and buy a red dot sight. "

Absolutely Amazing Choice
30/05/11
By: Lucian Provost

"I am going to start by saying that this weapon is simply amazing. The build of the rifle is sleek, along with te strength. Although the gun and magazine are both mostly plastic, they seem to be very sturdy am ready to stand up to the challenge of an airsoft skirmish. The gun is pretty heavy, but the weight seems balanced. This gun is ambidextrous, meaning that it can be used by lefties or righties. The bolt actually works, which is pretty sweet. Slapping the bolt down after a reload delivers a cool feeling. The battery is very easy to install by removing the rubber butt St"

My Experience
19/11/10
By: Gage C.

"This gun is amazing, definitely a step above the competition. It's not a hybrid gun like the headline suggests, but it's still an excellent airsoft gun. The only problem I experienced was the lack of room to upgrade the battery, which could be the reason why the gun has an average Rate of Fire, because the battery compartment holds an 8.4v battery. Yesterday I was involved in a game and my friend, whom has a high-end M4, and myself held off a team that had about 3 or 4 players that had Tommy guns and high-end AK's. So that will tell you something right there. The accuracy is good for mid-range engagement and if you equip a red-dot sight to it and sight it in, you will be feared on the battlefield. The best feature I liked was the ability to break down the gun without having to do anything major. The schematic that it comes with labeling all the parts is very handy if you want to upgrade the gun or in case a part falls off, very unlikely, and you don't know where it goes."

AMAZING GUN
26/08/10
By: Devin Ratte

"i got this gun for my birthday and it is pretty awesome. It's accuracy like they said is amazing i shot at a tree at least about 115ft away and i heard the sound when it hit. Also i would recomend getting a smart charger for the battery because the torque motor takes away all of the battery life when not fully charged by a standard wall charger. The sights are okay that come with the gun but the thing is they make the gun completely inaccurate. i hope this helps."

Niiiiiiiiiice
20/03/13
By: Devin

"Okay i received this gun a few days ago (as of now) and out of the box its looked SEXY. However my only complaint is that the free floating barrel comes with a few mm of wobble. This isnt noticeable when your getting shot at nor does it seem to matter all to much when shooting for accuracy. My suggestion is that in Addition to this gun you get a set of elite force iron sights. The ones that come with this gun are CRAP. Also invest in a grip, DO NOT TRY TO USE THIS MODEL AS A SNIPER RIFLE, you will be dissapointed."

Another good gun from JG
14/12/11
By: TJ

"Accuracy is above average, not amazing. The RoF is surprisingly high on an 8.4v battery. That is all that will fit inside the battery compartment, an 8.4v. The FPS is hitting the 380s, as seen in the video above. Buy a sight, the included ones are garbage. I took apart the gun (voids warranty) and I found a few things I do not like. Plastic Spring Guide Plastic Bushings Those are bad because plastic breaks. Plastic Bushings surprised me, usually high power guns like this come with metal ones. The piston is also plastic, with one reinforced metal tooth. That is fine, no worries on that. Everything else internally was either metal, or durable polymer plastic that wasn't a problem. Still an excellent buy. Update: The gun became near useless after the plastic bushings broke. A good gun, but you really should replace those ASAP. "

Needs Upgrades
14/07/11
By: Cory M

"I bought this expecting it to be able to be a DMR type weapon, but the internals are lacking and need upgrades for that type of play. Pros: - Good metal parts - Balanced around trigger - Long inner barrel and easy access - Compatible upgrade parts with TM and others - Easy to disassemble and clean - Good for the money - Relatively cheap upgrade packs Cons - Questionable plastic body - FPS NOT 420, that is with .12 - FPS 320 with .20's and could use upgrade - Plastic Tapet Plate, Spring Guide, Cylinder Head and Piston. Which could all be upgraded. - Safety switch can pop out if pressed too far in. - Battery space is limited, but EASILY modified by cutting the plastic plate in the back in half allowing the mosfet chip to sit under it. Worth the money, but if you have a little more buy it with a modify s120 or s130 upgrade kit. I got a suppressor to replace the orange tip, a metal foregrip, and a scope. And it looks Amazing!"

Great Gun

By: mory browning

"I bought this gun in february of 2012 and it is great. It has astonishing accuracy and a solid fps. My only gripe is that the set screw in the barrel got loose so I had to open up the gun to reset the outer barrel. "

A Bit Disappointed
10/10/10
By: Jim Riker

"I got this gun back in February, and out of the box it shot 320. Within three weeks the velocity dipped to 275. Got work done on it and found that the piston head was loose. Got the upgraded piston with all metal teeth, an M120 spring, and a 8.4v 1600 battery. Hit the chrono again and shot 270? Played half the day and the outer barrel let loose, and the set screw was no where to be found. Gorilla Tape fixed that. Even with all the problems, the gun is accurate, and I find that I am still outshooting higher priced G&G and KWA players at range. Unfortunately, I seem to be the only one in the review section that got half a lemon, but for the price the gun isn't all that bad."

What?
30/12/12
By: Domenic

"Hello, I purchased this ua-4 from airsoft megastore about a half-year ago, and the results have been disapointing. Right out of the box, i had two front sights and no rear sight. That isn't really a major problem, but it was annoying. When i first tried it out the charging handle came back half-way and got stuck. They put in one of the screws in the charging handle either backwards or it was a design flaw and it still doesnt work no matter how hard I try. Secondly, after the first test fire around 4 to 5 parts literally fell out inside the gun and I had to spend that night working on it. The only reason I didn't turn it back in is because I thought maybe it would work again someday. I live in Kansas, so there are no airsoft stores for literaly a few states. The gun's performance was superb, but it even felt like a hastily put together item made in china. I don't think it'll ever work, but hopefully i can sell it to someone for some kind of money someday."
