Question: I tried charging the battery and connecting it properly, but it still will not fire. ASny tips?
Document: Bought it, and after charging the battery for 5 hours and putting it in. It did not fire. The motor would move very briefly with every trigger squeeze, but like I said, it WOULD NOT FIRE. I called the manufacturer, and they told me to get a new battery, so here I am, writing this review instead of playing with my new airsoft gun.
It didn't work and it made the battery make a sizzling noise about 15seconds after connecting it. I had to take the battery and charger to get them tested after that. I was fortunate tohave not killed the battery. So right off the bat I needed to get a new charger($28.99). I recommend a smart charger.The magazine is not great at all. I really don't like having to keep winding the dial at the bottom of the magazine every 5or 6 shots.
I bought this gun because I couldn't bring myself to drop 300 for a tokyo marui. I like the mp5 so I shopped around and found this one. The gun is great, high rate of fire, and it hits hard, I shot my friend from around 20 feet and it left a blood welt.
Great gun, like other reviews battery is aggravating together in and it took a few minutes to figure out how to load the clip. The gun is built heavy duty, it is much more gun than I expected.
And I have quite a few dry shots.The battery is just okay as well. It does the job but there is nothing magic about it.The accuracy is all over the place and inconsistent. You can a few back to back that seem dead on then you get an errantshot that is wildly off. And this is with competition grade AEG BB's.The range is no where near 250 feet. (At least with .20g BB's.)
It is VERY difficult to change the battery. I have begun to just strap it to the gun, usually on the magazine. It is a powerful gun. I will not last long, and at $170 I expected much longer. I have now gone through 5 guns and the longevity has proven awful. This gun is fun to shoot. It just won't do it very long.I would not recommend it.
It has the type of flash hider that has a plastic piece you have to push down to remove the tip, but they glued the plastic piece so you cannot take it off. Some people said boil water then place the tip in it to losen the glue, I ended breaking mine getting it off. I then purchased a black one.3: The only real downside is the battery. It is pretty hard to get in.
AS the gun comes, in my opinion it is just okay.PROS: The gun itself seems to be well made.It is more robust than I thought it would be.It has a good heft to it as well.Contrary to other reviews, the orange flash hider can be removed but there is a small metal pin that was put in it tomake more difficult to do.People said it was hard to put the battery in. I had very little trouble.
Just got the gun and took it out to mess with. So far, what I see is pretty good. Shoots well, accurate, far.Couple of Comments here: When I got the gun, it was a little dusty, (I guess from sitting in a warehouse) Paint a little scratch, but not a big deal for the price of the gun. Like everybody else has said, the battery is tricky to put. Just be careful.
This gun has a really great feel, is sturdy, and great for a primary weapon or side weapon. It has only 2 flaws. One that you have to constantly crank the mag to keep the pellets flying. The second and BIG pain is trying to transfer the battery into the gun. It can take a LOOOOOONNNNGGGGG time. I was sitting for a good 15 mins the first time I transfered it. But I am managing now.
