Product Description

Features

  • Matrix / S&T Gen 3 Lipo ready gearbox with micro-switch trigger and quick change spring guide
  • Integrated MOSFET for improved power usage, motor performance, and trigger response
  • High strength nylon fiber reinforced polymer receiver, stock, buffer tube, grip, and carrying handle
  • Flat top receiver allows mounting of optics or other accessories (Removable carrying handle)
  • Adjustable 6 position SOPMOD style stock
  • Metal 300rd high-cap magazine
  • Aluminum M-LOK rail system w/ Picatinny sections; great for attaching accessories!
The Newly improved G3 gearbox developed under collaboration between Matrix and S&T offers the same features found in the G2 series such as a microswitch trigger, improved steel gears, full steel teeth piston, and aluminum cylinder. New to the G3 series gearboxes is an improved QD spring system which makes it even easier to swap to different strength springs without disassembly. The inline MOSFET features over discharge protection and the electric trigger features a magnetic sensor for improved responsiveness.

Patterned after the original ArmaLite AR-15, Colt rifles have been in the hands of the US Military as well as many civilian enthusiasts since the adoption of the M16 combat rifle. Through years of hard use and first hand feedback to improve and evolve the weapon platform, the Colt M4 and M16 has risen to be one of the most popular and trusted combat rifles around the world.

"Cybergun Licensed Colt Sportsline M4 AEG Rifle w/ G3 Micro-Switch Gearbox (Model: Black / Keymod 10")

Works well. Put a 11.1v LiPo and a 6.03 TBB on it and it'll beam the BBs across the field. Works flawlessly. Good range. Shooting with .30s, I'm hitting around 350-360fps. Accurate. Added a new motor and this thing just works.

"(MODEL: M4 SBR W/ 8" QUADRAIL / TAN) - Great entry level weapon for air softers. External parts are pretty solid with the quality of material. Internal components may be on the cheaper side but still durable enough to last some time before attempting upgrades. Would recommend getting as a first timer or as a second back up weapon.

"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.
