"First of all I purchased this rifle for its body. The zombie killer look is amazing. Also with this rifle you can have a reverse silencer that will extend into the RIS forgrip that makes it look awesome.

Body 5/5
No wobble at all between the upper and lower.
For grip does not wobble.
The motor plate screws actually thread into metal threads instead of a plastic hole.
I like the stock design, a little wobble but most m4's stock wobbles a little.
Overall a very solid feeling rifle.

Out of the box performance 4/5
I purchased a 250mm 6.03 tight bore barrel and new bucking (G&P) knowing stock buckings are not that great.
Before I did any upgrades to this gun I wanted to see how it performed stock.
This gun shot horrific. BB's only flew 40ft in every single direction. The gun sounded terrible.
Well that sucks time to install the new barrel and hop up.
After installing the new barrel and bucking the rifle shot 170 ft and could hit a players body profile no problem.
When purchasing this gun I thought it was going to shoot hot ~400fps .20g (to hot for cqb)
After the new barrel and bucking was installed it chronoed 347 fps .20g bb's. This is perfect fps for cqb. No need for the m100 spring.
Since I did not open the gearbox to install the m100 spring it cannot comment on it.Saved the m100 for another rifle. The only thing I can say is that it sounds good when shooting, and when I removed the motor all the gears were properly greased when looking into it from the bottom with a flashlight.

So I gave the performance 4/5 because the new bucking and barrel made a huge difference.
Note the stock bucking was covered in factory grease. This may be the issue but I cannot confirm.
If I did not purchase a new bucking and barrel I would give its performance 2/5 stars
