Pre-built Honey Badger carbine is basically what this is. Good range, accuracy is there, and the trigger response is solid with a tuneable trigger already equipped. The receiver controls are ambi too so good for lefties even.

Pros:
shoots far and accuracte
tuneable trigger
fast rate of fire
ambi controls
included suppressor

Cons:

This review will be copied and pasted over to the other version. I got twin boys, and of course they wanted the same gun. I got my oldest the shorter one and my younger one the long. Performance speaking, they are the same. They both shoot long and hard and can rip through bbs really fast on full-auto. My little is also a leftie so these are perfect for him with the inclusion of left-handed controls. Now that they've taken them out for their first games this past weekend, we can safely say these are the best airsoft guns you can get right now.

Pros:
-leftie friendly
-accurate
-comes in 2 sizes
-great for long range

Cons:

Pros:

This thing is just DANGEROUS in the best way possible
