"I've had this gun for almost a week now and I can say that the gun is fantastic for what you pay for! For $280 your paying for a full metal body, front flip up sights(similar to Troy m4 sights) are decent and get the job, wonderful preformance straight out of the box( Up to 150ft-175ft with a .25 gram bb. Also the rate of fire is outstanding with a 9.6v and even crazier with an 11.1 lipo!

Now knowing the preformance of the gun, I'm also going to recommend some upgrading to certain components of the gun if you want to make this AEG even better and also this is where the criticism of the gun come in.
1.) Get a new hopup bucking. The one it comes with isn't the best
2.) The rail it comes with may come loose after using a couple of times so I would suggest you put some type of thread lock on the inner threads of the rail of by a new one(real speke keymod would be great)
3.) A new stock, the buttplate that the original one comes with is awful( at least in my opinion).

Overall,if your looking for a great preforming AEG that is under $300 I would 100% agree on your purchase of buying this AEG. The 3 cons that I listed aren't necessarily the worst problems, they are just some pet peeves I've had with the gun. The last thing I can say is that if you want this gun, don't hesitate just BUY it!

"Great looking and an ok shooting gun. Internals are ok not great, cylinder head is nothing to brag about, very light weight and thin. I had my gun and used it for 1 day at ballahack and the cylinder head nozzle snapped. Their choice for selector cams where a bad decision as well. The selector plate is proprietary so changing it out to change out the poorly designed selector cams is not an option. The gears seem to be made out of a strong steel material and the cylinder itself is ok. Piston and piston head are plastic, it does have a quick change spring system in it and a mosfet. If you never had to open the gearbox to replace the internals or change the spring it would be a good gun for a beginner. But because of theit choice of selector cams and selector plate design it's males it difficult to re-insert the gearbox into the lower receiver. I've broken 2 sets of selector cams just trying to put the gearbox back in the lower receiver. After calling it every name in the book I finally broke down and contacted Classic Army explained the situation and they paid for the shipping fee to ship it to them and fix it for free. I shipped it out about a week ago, still waiting to hear from them that they received it. Hopefully I get the gun back soon. Hope this helps!
