Matrix / S&T Sportsline M4 RIS Airsoft AEG Rifle w/ G3 Micro-Switch Gearbox (Model: Dark Earth M4 RIS 8" Stubby)

"Decent gun, my nunchuck battery came broken but it needs replacing anyway. It has poor accuracy but good rpm. Im gonna put in a tightbore barrel as soon as I stop being so lazy and measure this ones. Its body is decent, however not what im used to (G&G). Only bought it due to low on cash and needing something for night battles. It has hope though.

"This is my re-review of this gun. I did one a while back. Looking at it now, it seems a little misleading, so here's my updated review.

I've owned this gun for about 2 years, so I think I'm qualified to do a review on it.
I bought the "Black M4A1 - 350 FPS" version. If you don't want to upgrade, I'd very much recommend this. If you do want to upgrade, you will not have a good time.

PROS
-Decent quality polymer
-Reasonably accurate
-17 RPS stock (9.6v)
-Good trigger response stock (9.6v)
-Extremely light
-Cheap (obviously)
-Rotary hop up
-High torque motor
-Super strong 18:1 gears
-Full steel teeth piston
-LiPo ready
-Rear wired (only a few, including this model, are rear wired)
-True quick change spring system
-14mm- threads

CONS
-Slow RPS (only on semi)
-INCREDIBLY proprietary gearbox shell, trigger and selector plate
-HORRIBlE compression (this causes massive fps drop)
-Wired to tamiya
-Meh hi cap mag
-Orange tip requires heat gun to remove
-Motor height likes to come undone (electrical tape will fix this)
-Included mags baseplate screw will unscrew itself during use (electrical tape will fix this)
-Outer barrel screws will unscrew themselves after heavy usage (blue threadlocker and electrical tape will fix this)
-Fragile wires
-Piston head screw came stripped, making it impossible to remove

CONCLUSION

Want to upgrade?
Step 1: Remove the mosfet, trigger, and selector plate.
Step 2: Replace the gearbox shell to allow for standard parts installation.
Step 3: Replace the nozzle with an aluminum, double o-ring one. This will increase compression, therefore increasing FPS.
Step 4: Replace the cylinder with an aluminum, double o-ring one. (If you'd like.)
Step 5: Install a mosfet, trigger, and selector plate of your choice.
Step 6: Reshim the gearbox.
Step 7: Some screws will undo themselves, which are listed in the cons above. Fix those issues with blue threadlocker or electrical tape.

Overall, if you don't want to upgrade this, it's an extremely solid beginner gun. However, if you DO want to upgrade, you WILL have a nightmare.
My recommendation? Grab some mid caps and leave the hopup stuff alone.

3/10

"Bought the starter kit, shipped and got only the gun and the mag, not even the correct manual.

"I bought this gun off of a different website for a cheaper price but it went up. This gun is ok I would suggest that it is for some one who wants to be a long range assault so no one gets seriously hurt. The FPS is actually 400-435 with .20g BBs. One thing I hate with this gun is that the butt pad is nearly imposable to get off. You have to squeeze two tabs to get it off but they broke on mine by the 3rd time i took it off. If you want this gun YOU MUST GET A SMART CHARGER to else you will destroy the 9.6v battery (mine is going). Also the battery goes in the back so if your butt pad breaks hen you will have to tape the battery in with black electrical tape. All in all it is an ok gun I don't live it but i don't hate it either. I would suggest it for adults or tall people only (No offense to shorter people but im 14) because the stock cant go all the way in and has to stay in the 2nd position or the battery wont fit.

Pros:
All metal rails and gears
high fps
ok feel

Cons:
2nd position or bigger only
bad butt pad
High fps so no evike airsoft events :(
Must spend a ton more or battery will die (and they arnt cheap)
Battery goes in back

For the guy below:
A bigger battery wont fit because the battery goes in to the stock. You are stuck with a nunchuck style 9.6v battery. Anything bigger or smaller wont fit.

"So, it started out alright, but the gun mangled itself. It stripped a piston, chipped the AR latch, bent the cylinder head and pushed the air nozzle in on itself. Also, the description is misleading, the inner barrel length is no wear near what is said, it said 360mm while it was 210mm. It also can run perfectly fine on 7.4v lipos even though it is said not.

Avoid this rebranded gun unless you plan on putting 100$ into it like i did

"This gun jams a lot I was so happy to get this gun but when I start to shoot it it lasted for 3 weeks I do not recommend this gun

"Ordered mine last year, recieved it, plugged in battery, and it did nothing but start smoking. Completely defective gun, and didn't fire once. Now it just sits in my basement and collects dust.

"WARNING DO NOT BUY
gun would not shoot with any battery no matter the charge so i returned it and bought another one and this one will only shoot with one battery i have wich is some old green chinese battery i found in my room i tried all kinds of 9.6v batteries and nothing works this gun says 7.4 and 11.1 lipo ready but those dont work either PLEASE dont waste your money or time buying this junk it is not worth it heres a tip if you look for reveiws of a gun on youtube and theres none on that gun thats a pretty good sign its not that good
DONT BUY THIS GUN!!!!!!
