This is a very solid gun. It is light and is perfect for the field. Before I received it, I had read on the product info it shot 350-370 so I believed i might be able to pass the chrono test on the CQB field that I go to. I wasn't surprised when it didn't pass the standard chrono test, but it clocked in consistently at 390-395. Perfect for field, not so much CQB. I bought it for field so I am quite happy with it.
-little to no motor whine
-high rate of fire even with a 9.6v
-Very very good internals
-unique look for an M4 variant
-Outer barrel has a very nice feel, almost unable to describe it
-fast trigger response
-perfect for field
-most M4 mags fit in the magwell
-the polymer barrel sort of scares me a bit, I feel like it might break off if i'm not careful.
-no iron sights, that wasn't a problem for me since I have a sight. Kind of ghetto if you are using iron sights...
-The dust cover stopped functioning after the 5th time i pulled back the charging handle, don' t know if that was my fault or just a glitch.
