"Bought this as a replacement for a cheap Black OPS Viper M4 I got at Wal-Mart after the trigger stop broke. Here's how I feel about it...

Pros:
-Stiff spring (isn't listed here or on package, guessing about M120)
-Well built, heavy, made almost entirely of metal
-Long air nozzle (sand or shave it if you need it shorter)
-Easy to disassemble and reassemble (compared to other GBs)
-Stiff/solid feeling trigger pull
-Seems to have a decent rate of fire with stock motor

Cons:
-Flimsy connectors on motor wires (mine needed to be bent at 90 degree angle, and when I attempted to bend it a little it snapped off. Had to splice in a spare off old GB)
-Rear wiring harness (to battery) is a bit shorter than I would have liked it to be.
-Selector plate is not fully compatible with all guns. Had to swap mine off the old gearbox.

Neutral:
-The holes for the retainer pins to the upper/lower receiver and to the trigger assemly don't quite line up so well. This COULD possibly be due to the fact that my receiver is made of ABS and is not as rigid or uniform as steel.


Overall 4 stars. I love it. :)
