"From what I can tell this is a well-made gun. It's got a sturdy construction. However, due to what I can only assume is the idiocy on Umarex's part, my gun came with a non-functioning piston. I plan on sending it back and I will only change this review once this is fixed for free.

"Always loved MP5 rifles, this one is true to the feel, had only two issues - 1) had to modify replacement mags as they did not fit into mag well. 2) trigger contacts not correctly aligned and burned contacts with in 2000 rounds, Repaired trigger and gun works flawlessly. This is a good cqb gun and the price is fair. Very happy with it.

"First of all I agree with Adam on this gun having a poor fire rate however the power it propels bbs is uncanny.

The quality and ease of this gun in tearing it down is incredibly exceptional.

To rectify the poor fire rate id recommend a Lonex A1 motor which is what I did to mine. Fire rate issue was fixed and even a 9.6 battery pulls this very well. for trigger response id recommend a 7.4 lipo if and only if you do the motor upgrade.

As far as accuracy the stock barrel worked better for me than even a 6.01.
