"I have had mine for a year now I think and I have beat the poop out of it, solid gun, nothing broke that was not my fault. if your mags are leaking you need to lube them, if not holding gas you need to purge them.

Great rifle for a great price, we have verson 2 mags so nothing should be leaking out of the box. gas guns user error is magnified.

"Received the rifle about a week ago. Delivered on time and packed well. After reading several reviews of this rifle, the first thing I did was strip it down and clean it. Lubricated everything and re-assembled. Loaded the mag with .30g BBs and gas and had some fun. I did need to adjust the hop up as it was shoot low. Once it was dialed in I was getting a very tight grouping at around 45-50 feet.

Did not have any issue with the mag leaking gas, in fact, I could unload all 30 rounds and additional 15 before the gas gave out. There were no issue with the fit of all the pieces, Every thing was tight and fit well

Very impressed with the fell and weight. If you are use to lighter AEGs it may seem heavy. I do like the fact that the clip mimics the real steel counter part when it come to the amount of BBs, seems more realistic. While spraying several hundred rounds may be fun, it's more of a challenge wen you have a limited amount to shoot with on the field :-)

Bottom line this is a great gun at a great price.

Pro/con (depends how you look at it)

- Loud crisp firing sound


- Good weight and feel
- Realistic amount of rounds
- Solid construction


- Costly magazines
- Hop up difficult to adjust
