"I would have to say that the metal gear box is very well made and also that it shoots around 370 to 400 fps with no promblem. Now the cons: the outer rail of the gun got really loose after 1 month it is so loose that you can turn all the way around.

Binafits: the outer barale is very solid and it is light weight for the price of this gun and the way it is made I would highly recommend getting this gun.

"I have to say, I had mixed feelings about this AEG. I love it because it's very unique but also hate it because of the issues I had with it.

The first time I brought it out to a game at Gampod Combat Zone I ran into issues within the second round. Granted nothing happened that caused the gun to malfunction, but the externals could've used a bit more care and thought. The outer barrel is unfortunately a three-piece barrel which is only held in by 2 tiny hex screws, not by the delta ring like most other AEG's, and those tiny screws came loose due to the gearbox vibrations. And even the delta ring isn't the best when it comes to securing the barrel because it's completely different from almost every other setup I've seen so far, you have to see it for yourself. But, these issues are very easy to fix, all you need is some soft loctite and you should be set. And when it comes to the hand guard, it's a mess. When I first put on the bottom rail, I noticed a major flaw in it. There is a large piece on the front of the rail that basically prevents you from slipping it off easily by pulling back the delta ring. In fact, I actually broke it off and was worried. When I looked at the instructions, it turns out that they specifically tell you to put the battery in first, then the bottom part of the hand guard AND THEN you screw in the rail. With that kind of setup, it's essentially impossible to do an on-the-field battery swap. I would recommend just using a dremel to cut off the front portion of the removable rail. Speaking of batteries, only ONE kind of battery will fit into the hand guard. Forget about trying to fit in a NiMh small type, nunchuck, or PEQ type battery. You have to go with the one that is recommended, which is a rather dumb design if you ask me. What happens when the battery isn't in stock? You're basically screwed until it comes back in. But at the very least, it's a very snug fit so you won't have to deal with a rattling battery, but if you choose a li-po you should have no issues. Another problem is the mag compatibility. The mag that it comes with is positively snug with little to no wobble and that's fantastic. The problem with that is if you use any other mag, they wobble like nobodies business. This thing is rather proprietary when it comes to certain things, and yet again, what happens when you can't find the mags that fit this thing perfectly? Oh yea, you're basically screwed. Another little issue that I had is that the selector switch is WAY too smooth. Some might not find issue with this, but I did when I was cornering and had to switch from my right hand to my left. My left hand kept bumping the switch and setting it at an off angle. I had to completely disassemble the whole gun to wipe away the excess lube that was around the area in order to get a more positive and secure click out of it. Did I also forget to mention that Most, if not ALL of the externals are polymer? Now, this could be a good and bad thing. Good because this makes the gun cheap and light. Bad because to some it may seem TOO light and items like the outer barrel and buffer tube might be the first things to break or have issue with. What I would suggest is getting a proper one-piece metal barrel and metal buffer tube to prevent much issue.

Now that the bad is out of the way, let's talk about the good. The gun may be light, but that will prevent much fatigue. This thing fires incredibly fast on a 9.6v and is rather consistent at around 390-400fps. It looks REALLY unique and has similar ergonomics to a Magpul M4. Not to mention that it has a King Arms gearbox and plenty of things that you can do to it to upgrade it. And you are getting it for $150 retail (I personally got it for $115 which is what it SHOULD stay for the rest of it's shelf life)

Conclusion: Get this gun, but do expect to swap out the outer barrel and a few other parts, clean up the extra lube inside to make things less smooth, and you'll have to get extra mags that are specifically made for this gun to prevent miss-feeding. For the price you are getting solid internals with slightly iffy externals, but then again, it's $150, what were you expecting?

"don't listen to the people who said it's bad. This gun worked absolutely fantastic. After about 4 months of having it, WITHOUT repairs, or modifications, it STILL runs beautifully. Of course barrel cleaning was in order from time to time, but that doesn't really change anything. Anywho, let's get to the details;


Very Lightweight (Perfect for rushing the enemy team)

Very strong and durable nylon polymer build

Solid FPS of 390+ (After 4 months of shooting it's only went down 5 fps)

Very cheap for a solid gun

CAA Magazines are the perfect match for this gun, solid/perfect feed and extremely durable mags (Plastic mags, but really thick plastic for extreme durability)

The battery recommended lasts extremely long, and fires very fast.
(I was able to play 5 games, for 3 days(not in a row), and the battery was still charged(Without charging between days/games))

The handguard isn't the prettiest thing out there

Low rail space on the hand guard (e.g. upper rails and side rails)

Had to tighten the barrel and buffer tube after about 3 months (Just by a little, not alot)

Mags require a very slight angle to the left or right, and a mild slap to stay in.
(Could just be my gun, might not be the same for every gun keep in mind)

Tight battery space in the handguard, but it still fits fine and leaves enough space for the wires.
