Matrix Metal 300rd Hi-Cap Magazine for M4/M16 Series Airsoft AEG Rifles (Color: Black / Set of 5)

"Love these mags.

Pros: Full metal
Solid build
Compatible with most m4s
No wobbling around
Cons: kind of thick so that it doesn't wobble
Chinese made :(

"I bought 6 of the mgazines and only 5 of them work other than that great product!

"to this 1st guy who wrote a review,

AT ONE Point i was about to get the echo 1 er25k. The only thing i had against it was the price and the thing with the mags.

1st of all, sr-25 mags are EXPENSIVE and a decent 300 or 450 round one cost about $30

No m4/m16 mags work with the er25k.

If you want a gun with the same look, get the A&K sr25. it takes m4/m16 mags its only 210 its full metal and you could uprgrade it to a crane stock for an extra 50 bucks and it would be the same thing as er25k except without the best airsoft name ever (echo1) and mags are cheaper and easier to find.
And if you want an echo 1 because of the holy cow special, You could spend $50 for the crane stock, and the dboy 300 round mags for 12 dollars and still save money.

Hope i influenced your decision

"I keep asking myself "Would this fit a Jg m733 tsf aeg rifle." Im not sure and im wondering if someone could tell me.


Webmaster: Yes this mag will fit no problem!!

"i got these mags not to long ago so i cant tell of any problems yet, but i bought 1 for my JG m4a1 and they are almost exactly the color of my jg mags but they dont click into place very well without putting a litte force behind it. but they should be fine after lubing them so good for the price but you get what you pay for. id hate to know i had $18 (the regular price) in these though

"It is different from the echo 1 because the battery is wired in the stock so it's kind of a pain to find a good gearbox for it but all in all it's a really nice gun

"Same as the other guy below me but I got this with my JG M4A1 its great feeds well but I hate winding the damn thing after about five to seven times!

"its an ok high but scratches easy and gets kinda tight with metal bodies and even my tokyo marui's i recommend getting a better one like idk classic army or tokyo marui idc but it works ok buut never misfeeds but its ok i guess if you like your make to have a tight fit.

"Fits my gun just fine, but feeds not so great. Hopefully I just need to break it in more and it'll feed more smoothly eventually. I've bought several similar mags from different makers and they all seem to have feeding issues. The only thing I can think of is that they must have weak springs in them. I can see now why a lot of people recommend mid caps

"They feed really well on full auto for some reason, but not on semi. Might be the gun. VFC Scar L Standard

"Will this magazine work with my M733 right back plez

"when I first got this IT DID NOT WORK. When I would try to wind it up i would get about 5 twists and thin the spring would jump off and you would lose all your twisting. I had to take the entire mag apart to try to figure out why it wasn't working, when i had it open i found that a lot of the internal parts of the mag were broken. To solve this I used a lot of duck tape and and glue, in the end I made the mag work but it only works on semiautomatic. To conclude, I got a defect mag and it does not work the way it is supposed to. From the other reviews it appears the mags work good on average but mine just didnt work. I am giving it 2/5 because I was able to make it partially work.
