Matrix / S&T Sportsline M4 RIS Airsoft AEG Rifle w/ G3 Micro-Switch Gearbox (Model: Dark Earth URX 3.1 12")

"this is a really great gun. i went to my local hardware store and got camo colors and pained it it comes with a nunchuck batery great for price i cant wait to use it in a battle. this is a realy powerful with perfect accuracy i got a a&k 5000 round box and barley fits in it buy if you have the money beacuse it is perfect(__--_)

"what kind of battery does this gun come with? can you put a mock silencer on this gun?

"its a very good gun. but the mock suppressor does not remove or atleast i dont know how to. but the way it looks it doesnt simply screw off so no TM tracer kit for this gun. get the tracer mags they work great.

"If you put in a tightbor that will give this gun the same range as a Jing Gong M4/M16.

"This gun is a great beginner gun. Internals are decents and so are the externals. It did chrono over 400fps out of the box but settles in at 370fps. Overall a good gun to test the waters in airsoft. m203 is awesome

"Got the gun and works pretty great just my fps is rather low then what the comments are saying. I got it chronographed and shot at 280 which is much less then what others are saying. I'm using 0.20BB's with these by the way. But I mean besides that the gun is great. If anyone has suggestions as to why my fps is so low then please let me know!

"I have 2 of these rifles and let me tell you they are tanks. Both rifles have not stopped working in the 4-6 years of owning them. They don't have a few issues.
Issue 1 they don't like P mags, or any type of mag pull mags.
Issue 2 the rotary hop up moves every once in awhile.
Issue 3 if you get a plug and play mosfet they will only work every other burst. Then stop working, to the point of removing the battery and the mosfet. Such as the avacado burst wizard.
However they both have not had any replacement parts other than the hop up buckings, and just now a motor.

I really wish they would accept p mags, they prefer the metal mags.

"Very Good But The Barrel Wiggles out the box

"I bought this gun brand new with the package bundle. Once I unboxed it the gun felt amazing the weight was right in the middle, not to light and not to heavy. The flip up sights have to be my favorite thing about the gun. The next day though I took the battery off the charger and plugged it into the gun but nothing happened I couldn’t figure out if the battery charger wasn’t working or if it was the gun itself. Plus the condition of the button on the charger was poorly made.

But over all great deal, just wish for the money spent the charger could’ve been in better shape.

"I bought several of these for my training company. After multiple uses with relatively new users, we've had no issue with them at all. Durability and reliability has been very good.

Great starter gun for a new player, and good value for the money.

"So I recently ordered this gun and it’s awesome. Right out of the box with an 11.1v lipo it’s super snappy, it’s got a pretty healthy ROF, has an awesome feel to it, it’s nice and accurate with the stock iron sights, all in all for the price range that’s on it it’s an awesome gun and I highly recommend it.

Now, I only gave 4 out of 5 stars due to the fact that the listing says that it’s wire in timaya. It’s not. At least mine wasn’t. Mine came wired with deans which is awesome cuz I was going to switch it but slightly annoying because I ordered a battery as well that was timaya only to find out I needed deans. The other irritation is the listing says the barrel is threaded 14mm positive which is lefty loosey righty tighty. IT IS NOT 14MM POSITIVE. IT IS 14MM NEGATIVE!!! That’s a bad mistake to make because if I wasn’t careful and already not trusting the listing, I might’ve destroyed my outer barrel trying to remove the factory suppressor. The glue is also insanely difficult to break loose. I tried to boil it and I still had to put some serious force into breaking the glue and have slightly messed up the finish on my outer barrel. Not a huge issue, it’s not going to make or break the gun. But it’s an annoyance for sure because now I’ll have to either repaint the outer barrel or replace it. I got the M4 Sportsline with 10” keymod

"Got this a while back, have used it at many fields and has been my main gun for a year now. Got out of the sport for a while and wanted to get back into it. Found this guy in the Airsoft go package. Red dot is a little wobbly, and the extra mag they give you doesn’t fit or feed. Aside from that, very solid gun. Good weight, durable. I had my selector pop off but was an easy fix. All in all great gun for new players or old. Would recommend this to anyone who is on a budget but looking to get into the sport.

"great trigger. responsive. accurate enough. only four stars because polymer mags do not work on this gun. I have tried 4 different brands of polymer magazines including Evike BAMF, Matrix, G&G, and some unknown brand. Only magazine that will lock in is the metal one that came with the AEG.

"I bought 3 G&G polymer 120 round mid-caps and they do not fit into this gun very well at all.

What would be a recommended mid-cap magazine for this gun? Looking for a magazine that is easy to click in and fits good.

"(updated review)

I bought the "Black M4A1 | 350 FPS" version.

I have owned this gun for one year now and used it on the field twice and both times it served me well. One of those times it jammed, but nothing catastrophic happened. The motor height had to be adjusted.

PROS:
Super high RPS (17 w/ 9.6v)
Good trigger response
Lightweight
Made of polymer (super good quality polymer)
Stock gears are INCREDIBLY durable (no teeth stripped despite not being lubed/cleaned)
Piston has full steel teeth
Easy to adjust hop-up
MOSFET built in (lipo ready)
Can hold down full-auto for a long time with motor/battery heating up (only do it with a 9.6v though)
Quick-change spring guide

CONS:
Bad shim job
TERRIBLE compression system (this results in much lower FPS)
Cannot install Gate TITANs
Tamiya adapter
Slight stock wobble (to be expected with most stocks)

RECOMMENDATIONS:
Replace gearbox with one that can accpet Gate TITANs (this one does)
