Cybergun Licensed Colt Sportsline M4 AEG Rifle w/ G3 Micro-Switch Gearbox (Model: M4 Commando w/ Crane Stock / Black)

"I bought the Block 3-10.5-URG M4.
For the price, externally, it’s awesome. You get a mock bolt/bolt catch, a ambidextrous charging handle, metal components, and a duranle polymer body.

Pros:
-Metal components
(Charging handle, Trigger, Trigger guard, Fire selector,Mag release, Bolt catch, barrel, motorbox)

-Nice weight
(Not a too heavy, doesn’t feel cheap)

-Rotary Hop-up
(Easy to use)


Cons:
-Bolt catch snapped after two months of hard-play
(Don’t do slam the bolt catch too vigorously. Just pressing it will extent its lifetime.) King Arms also sells bolt catches that work on this M4.

-Charging handle pins popped out once.
(A way to prevent this is just adding a little bit of duct tape onto the pinholes on both sides of the charging handle.)

-Stock wobbles/creaks a lot after a while
(It won’t be to the point that it’ll mess with your aim, but it is really annoying to hear it creak all the time)

-The mock bolt bent a little bit, obstructing it not to close the entire way.
(It’s not at all something that will break your rifle, but it is an eyesore to see it not completely shut all the way. But its best to leave it to prevent further breakage.)


Overrall, externally it’s absolutely amazing for ~150$. Most of the cons I mentioned can be prevented or fixed fairly easily. I can’t say much in how the rifle shoots as I haven’t done a lot of shooting to judge.

"Love it!, Great functionality and the trigger is really responsive!, and it's also light weight and I love that the battery is in the handguard to!!!, highly recommend!

"Gun only works with most of my mags and fires well. Very accuate and good rate of fire out of box. Hopup works well and good FPS as well
