||This kit was excellent for my G&G M4 DSR except for a couple things.
-Functioning Bolt Catch
-Full Metal Hopup
-Awesome Evike Branding :D
-Designed for a rear wired gearbox
what it doesn't come with but could (and you'll need)
-Charging Handle (does come with the spring, and forward piece though)
All in all an excellent kit! looks great! just make sure you have the other parts for it.
