"This thing was incredibly amazing for my M16. It was full metal, nice engravings, amazing motor, great RPM, high FPS, all around good.

Great quality
Looks cool
Works well for M4s and M16s

Heavy( full metal)
High RPS
Deans connector

Short deans wire protruding from the back
No hopup included
Dust cover stays open, you cannot latch it back so it protects the hopup

"This kit is for sure worth the money. The engravings give it a nice touch. The metal is of a really good quality. This is really made for a field gun unless u downgrade the spring like I did and add gears designed for high speed.
-around 420 fps
-decent speed-18rps
-good internals
-ball bearings
-laser engraved
-decent motor
-no upgrade needed
-lets you build YOUR dream gun
-The wiring sucks; buy new 16-18 gage wiring and solder it yourself
-The motor takes a second to get to max speed unlike a lonex so trigger response isn't the best
-gear ratio is normal which isn't good if u want high speed
-Wired to deans (easy fix with a $10 soldering gun lol)

The gearbox is great if you like tinkering. I've taken mine apart over 30 times and it still works fine. Fare warning, don't try upgrading this with other parts if you don't know what you're doing. If you do, no harm done because there's not a lot you'd have in this kit. Honestly this kit is a great deal by evike. Because evike offers sooo many m4 parts, you are able to build what you want. It makes my m4 seam more personal because I built it from the ground up. Get this kit and you won't be disappointed!--If you want a cqb set up, buy a lonex, high speed gears, an m100 spring, and new wiring (16-18 gage). It creates a SICK weapon and is what i use now!
