"A lot of the reviews on here seem to be pretty vague, so I'll try to put more into it.
Class: Support gun
Role: Suppressing fire, Area Denial, Intimidation
The Matrix MG-42 is exactly as you would expect it to be. It is heavy, it is awesome, and it can lay down some serious fire when it works correctly (which is often when you get used to it.) This weapon is heavy and meant for locking down an area, so don't buy it expecting to be Rambo, or expecting to be able to clear rooms with it as you will only "die" tired.
My biggest complaint about this MG so far is the initial build. My gun's rear sight came locked in a flip down position due to poor tolerance, and I have to take the sight apart every time I want to flip it up, so I leave it in a "Flip up" position. The Bipod was cross threaded when it came in the box, naturally the first time I tried to use it the threads broke, and now I'm down a bipod. As other people have stated, the charging handle doesn't stay in, since it's only aesthetic I just leave mine out. Unlike other users I didn't have a problem with "Wobbly stock," but even if I did it wouldn't matter since the stock is meant to hold your battery anyway.
The gun is hard to use at first, a lot of people are complaining about locked up gear box, and feeding issues, but I can tell you it's most likely user error. I had those issues myself, and it only took me a couple matches to get it perfect.
The way the gun works is the Box Mag is connected to the gun so that it can time the rounds with the firing of the gun, however it only activates with a full trigger pull (You can pull the trigger halfway to activate the gun but not the box mag). Now if you just hold down the trigger too long the mag will feed too many rounds and cause a weapon jam, this means you have to play with the trigger to make sure you both have rounds, and that they don't over feed. It sounds complicated, but believe me it's easy to get used to.
The weapon is full auto only, and cannot be used to clear rooms. Sure the gun comes stock with 350 fps, but since you can't clear rooms anyway, and I wouldn't recommend constantly moving around with it, I would recommend increasing it to 400 fps (when the game allows) since you shouldn't be getting close with it anyway. There is currently no sling, and no sling mounts but the condor 3-point sling can be adapted for it.
Ultimately, the MG-42 is a great and cheap alternative to the other MG-42's out there, but since I haven't tried the other support gun's out there, I can't say how it compares.
If you buy the gun, make sure to take a close look at all of the parts. Use it a little bit, and make sure everything was built correctly. Once you get past that, it really is an amazing gun.
Great Support weapon (when you get used to it)
High Ammo count
Cheap (in comparison)
Heavy/bulky (it's a stationary gun, what did you expect?)
No sling mounts
"This weapon is very deceiving. The feeding system is completely dependent on one little plastic piece. The internals are all very poorly manufactured.. It just seems like they tried to push this weapon out in a hurry without putting any real thought into it
It's a cheap mg42
It has an extreme intimidation factor
It makes heads turn
Woble in stock
Faulty feeding mechanism
Drum mag is garbage and will go continuously
Screws are not locked in
Charging handle doesn't stay in place
I would not purchase this weapon, unless it's just a display piece
"The Matrix MG42 at first sight seems to be the ultimate airsoft gun, heck, it's an MG42. To keep everything simple, here are the pros and cons:
Its an MG42
-Wobbly parts: Iron Sights, loose screws
-The Charging Handle barely fits and usually falls out
-The gun being unable to shoot BBs! Major feeding issues with the Magazine!
At first, the magazine seemed pristine, until you pull the trigger and the magazine fails to feed BBs into the gun. Also, the interior and wiring of the magazine is very poor. Shipped the magazine back, got a new one after 6 weeks and it still didn't work! I sent the magazine and gun to a professional for a repair. I still cannot tell you how hard the gun hits, but the rate of fire is unbelievable.
Well, if you like the MG42 buy it, but be prepared to spend extra time and money to get this fixed. With all the problems associated with this gun from my experience and other reviews, $450 is not worth the trouble. This gun should be flawless out of the box; I've had better luck with spring guns for my part.
