Cybergun Licensed Colt Sportsline M4 AEG Rifle w/ G3 Micro-Switch Gearbox (Model: URX4 PDW-S SD / Black)

"This is a very good AEG from what I can tell. It has a nice weight to it (especially for a polymer receiver gun), and all the features of the gun work pretty good. I haven't gotten a chance to shoot mine yet, so I would recommend people refer to other reviews for it's shooting performance. The only downside I found so far is that mine didn't come with an instruction manual. I got the M4A1 w/Crane Stock M203 Grenade Launcher package, but niether the gun or the grenade launcher came included, so I had an extremely difficult time with some of the attachments I wanted to put on. There are a lot of good reviews for this gun and similar AEG's on YouTube which go over wider topics like battery storage, gearbox replacement, and other topics, which was helpful. However, there were two things I had to figure out on my own. First off, I wanted to put a full stock on the gun. I didn't know that you needed to remove the buffer tube to do this, so it took me some time to figure that out. You have to unscrew this really inconvenient screw in the back of the buffer tube, then carefully extract the screw housing so that the battery cable can pass through and you can remove the buffer. Then you have to remove the black plastic piece that helps hold the buffer in place, and replace it with one included with the full stock. There's this giant screw that holds all this together once you get everything else on. Then there was the grenade launcher. Not only did I not know how to attach it, but there wasn't any good videos on how to that I could find. Your supposed to pull this quick release latch on the frontwards part of the launcher (the clamp that attaches the launcher to the front of the barrel), but on mine it was really really stiff, so I was terrified that I was going to break it. Eventually, I got it to work, but it took me like 20 minutes. All in all, the gun itself is good, but the lack of an instruction manual included is a problem.

"I got this as my first aeg, was not disappointed. The MK18 style has a metal rail and high quality polymer receiver. I got the Go Package, but can’t recommend the Go Package because of magazine incompatibly with Bamf gen 2, the gun itself is great though. I used a 11.1v Lipo and it had a great ROF.
I’d highly recommend this to someone that wants a m4 that is compatible with lots of upgrades and durable build quality.
The first thing I’d recommend to upgrade is either a new steel barrel and bucking, as the one it comes with is brass and mine came somewhat dirty, or a new motor. 5/5

"I got my gun in a box of awesomeness and it preforms quite well for the price. If you are new to airsoft I would highly recommend this gun.

"This is my first gun and it is truly amazing. Has a great, very lightweight trigger for a fast trigger finger on semi-auto. That full auto is also perfect. Lottery my only issue is the batter pack spot. It is a little bit difficult to get the batter cover on with a battery in there but after a second of adjusting it will fit. Amazing 10/10 gone. Would recommend!

"Alright, I bought this gun as a cheap backup/loaner for friends and I was pleasantly surprised to see it easily compete with my other guns. It shoots really straight and range is acceptable. One thing I noticed was the hop up was backwards. When you open the bolt to adjust the arrow points down. The down arrow actually means more hop. One mor small complaint is the wobbly stock. Overall a fantastic gun. 10/10

"I got the URX 12 and I am highly satisfied! This was my first airsoft gun and I really enjoyed using it. I would recommend this for beginners. It is very reliable and shoots great.

"This is my first gun I got getting back into airsoft. It's been about 6 years since I sold everything and I had a G&P MK18 that I loved. I didn't think at this price point it would be anywhere near as good but it is. The light trigger feels amazing and with a 11v lipo is shoots fast and hard. Definitely a great beginner to mid gun! My only small complaints: I wish the orange tip would just screw off easily and I wish the stock had a few mm more room for the battery, cause its a bit of a tight fit for mine

"Shoots straight and feels good

"This gun is a good backup or starter gun. Its completely made of a polymer, which makes it light but looks pretty manufactured. The only thing that isn't plastic is the gearbox. The adjustable crane stock is wobbly, but sturdy when you put pressure on it. The hand guard (I think that's what its called) is also wobbly.
The battery compartment is in the butt of the stock; you have to remove the initial butt and then a smaller divider piece that is a key element to the look of the stock. The battery connector is short, so you have to make sure that the stock is completely pushed in. Then there's the hop-up. The mechanism to access the hop-up is also made of polymer, so when I tried to close the access door a couple of time I manually had to close it. The hop-up itself is a red vertical wheel and is good for fine tuning. It's big, so you should be able to see it. I haven't tested the FPS yet, but I expect it to be close or a little under to what's advertised when using high quality bb's and a high-power battery.

Some things I recommend for this gun:
1. A 9.6v 1600maH lipo battery. The box the gun came in only had the gun and magazine, and that's it. No battery. I compared fire rates with a 8.4v and a 9.6v battery and the 9.6v makes the fire rate significantly higher when on full auto. When firing there isn't a massive ringing sound and the firing sound itself is pretty short.
2. A mid-cap magazine. The magazine that comes with the gun is hi-cap which is fine, but I personally enjoy mid-caps since I don't have to wind anything.

Other than that, this gun is enjoyable and I would recommend it for someone looking for an affordable starter or backup gun. You get what you pay for, for a $140 airsoft gun.

"With a little downtune(very easy with the quick change), this gun is a solid CQB choice. Nice weight. Nice length. Quad rail is nice. It’s a little louder(poppier) then the full sized, premium, metal variant.(which is a really solid outdoor rifle)

I personally have never had an issue with a Cybergun.

"Got it last month and went to battle with it twice. So far so good, no complaints and works as expected. Would recommend.

"Great for the price and much better than many other guns around this pricepoint. Nice handguard, grip, trigger, ROF, and sights, I just really hate the end of the stock as it can fall off when playing as almost nothing keeps it in place.

"have a pretty good weight to it no wobbles at all like other M4's out there elite force magazines works fantastic with this rifle and the rps is (long whistle noise ) nice and its LOUD must buy !

"Well i bought it a few weeks back. EXCELENT RIFLE for the price, shoots amazing!

"Big fan of colt and this is a really awesome rifle to play with. I am glad I got it!
