I recently purchased the Matrix M4 Sportsline AEG for $99.00 on sale. The model I got was the M4 COMMANDO version, which is the smallest model, (great as a backup to my Sniper rifle). When I got the package, it was in a nice Matrix box. Inside the gun was nicely secured. After checking for damage, I grabbed a charged 9.6v battery, 25g bb's, and fired it.
Sturdy body
Nice RESPONSIVE micro-switch gearbox
Great ROF (for $99)
300 rd metal magazine
Good FPS
Pretty dang ACCURATE

Cons: Have NOT found any.

"I recently picked this up as a backup/loner AEG, but after giving it a test run out in the field I gotta say that it's a seriously well performing AEG right out the box. The stock hop-up and inner barrel with some minor dialing in had no issues and hopped bbs flat and very straight for a stock barrel. Now the real money in my opinion is in this AEG's micro-switch trigger which makes semi-auto on this baby super consistent with no accidental double or triple fire and has a functional trigger response for quick shooting. Now let's talk about the polymer receiver which EVEN has a plastic buffer tube and plastic buffer tube plate.. while not aesthetically pleasing in its finish, cuts down the weight and helps give it a good balance. Last, but not least I would recommend replacing the battery stock in the long run. The battery stock it comes with is functional, but of low quality and there are better budget friendly options out there.

In short,

PROS: Micro-Switch Trigger w/mosfet runs great with 25C burst from an 11.1v Lipo.

Good balance and Lightweight.

*My opinion* No EBB shenanigans, completely unnecessary feature in nearly all cases.

Good stock hop-up and inner barrel. No modifications needed out of the box.

CONS: In the long run, this gun is not going to be super upgradable aesthetically beyond popping in MOE hand
guards to add more accessory options. (Would not sink more money into this one)

Low quality stock, would replace but it is not an immediate issue.

No buffer tube sling point for using a 1-point sling, have to use a 2-point sling to carry it stock.\

Orange Flash Hider is secured with a metal pin on the bottom of barrel, not impossible but annoying to
remove. (Recommend caution in removing as metal pin is recessed into barrel which prevents orange tip
from rotating.)
