"Whoever said they dont work with the S&T Matrix M4 is lying lol. It does, but its a reaaaaally snug fit. You have to break them in your gun. Then the rest of your mags literally slip right in lol.

"The only mags that will work in the Matrix/WA GBBR!
Not the S&T/WA they mistakenly confuse these with!
These will only work in version 2 GBBR! The full metal Matrix rifle with Matrix Engraved on the receiver!

The S&T GBbR that look similar will only use version 1 Gas mags with a rounded off Valve reset(the reset on the top right side of the mag.

These mags here are steel mags with no body pins,upgraded anodized valve that works with the weak hammer springs that come in these.
These work far better than the standard mag all around!

The V2 Gas mags use a sharp pointed reset valve that’s twice as tall as the V1 Gas mags.
Your S&T/Matrix /WA uses v1 not these V2 mags!
I love these mags but wish they were under $60!

The matrix WA V1 mags fir the other rifle are in stock right now aswell, just don’t attempt to ever take them apart! Especially the body mid pin! Only oil them and fill with gas! If you let the gas drain they will leak! Keep them oiled and filled at all times and you’ll not have issues!

To see this mag and the other new Rifle mags fir the other rifles check out “Ultra Collector Custom Airsoft” on YT! It’s the “Amazing New S&T Matrix/WA gas mags EVIKE video!
Hope this helps!

"I am using this mag with the Matrix full metal GBBR. The fit and finish of the mag is solid; I was a bit surprised to see that they were actually more of a silver / light gray color. I purchased a total of 5 mags and all have proven to be leak-free and to feed very well. It took me a few minutes to figure out how to load the mags with the included speed loader but now loading is a breeze. Another surprise came with the capacity of the mags, as these are actually 40+ round mags, not just 30rds.

For use with the Matrix full metal GBBR, the fitment is very tight. After a few mag changes it becomes easier. Be sure to practice before playing as the mags became stuck in the magwell a couple times. This happened only once with 2 of the mags.

Overall I am very impressed with the initial quality and performance of these expensive mags lol. I would recommend them.
