Matrix "Universal Feeding" Full Metal 500rd Hi-Cap M4 AEG Magazine (Color: Black)

"This mag works well with my Daniel Defense M4. No feeding problems or issues fitting in the mag well itself. The only bad thing i noticed was how small the reservior (where the bbs' go when you wind the mag). The first time you wind it, the reservior loads about 20~25 bbs' in it. But, as you continue to fire the gun it only loads around 10~15 fully wound. As always with these cheaply made products, this could just be a defect on my magazine.

Pros:
-quality material
-grey-ish color (pro or con?)
-works with almost all brands
-feeds well
-PRICE $$$
-500rd !!!
Cons:
-small reservior (might just be my mag)
-a bit long .. for CQB players

Pros _ Cons ... i would highly recommend this product..

"I got these for my arx 160 elite and it didnt fit D: .
besides that they were metal and felt quality. I wast too happy that it said 450 rounds , not 530. D: overall, good quality mags , they should only be only m4s if u put it in a gun

"These mags are massive! They are about the size of an AK's mag. They feed well and have not jammed my M4. They are around an inch and a half bigger than normal M4 mags. over all a great deal for 13$

"I ordered this mag with a few others about a week ago and im pretty impressed. Fits a little snug in a kwa sr10 but feeds good. The only reason i gave it a four star is because it came and the mag was all scratched up. Pick up more than one of these because they are a steal for 16 bucks!! full metal!

"this mag is good feeds well and mine came in black, i could fit 569 in mine and out of that it only jammed 3 times i dont know if thats bad, you judge

"This mag seems to be made well but does not fit in a G&G Raider M4. It goes it but doesn’t catch well and falls out at the slightest movement.

"these mags do fit alot of bbs and are pretty good but ive had issues where it wont automatically stay in my gun (G&G cm16 combat michine srl) and alos will fall out randomly when shooting

"Good quality magazines. HOWEVER I tried them in both a KWA SR10, a KM4 RIS and a KWA SR12 and they were all extremely tight Fits. Required two hands to remove.

"This mag feeds well and does its job, but I honestly don't like it. The reason is, is because most matches when I play I don't need 500 rounds (which was dumb of me to buy) and it is also so big making it difficult to lay down.

Pros:
A lot of ammo
Does its job

Cons:
Huge

"So bad. Out of 4, 3 were broken in about 4 weekend of play. Not even full days

"Sadly these awesome looking “universal” magazines would not work in my Echo1 XCR. The mag was way too wide and had to be muscled into the mag well and then I’d get a single shot before they would double feed. I’m a little disappointed in spending so much for magazines I can’t use.
