"Bought this mags for my Matrix MK18 build and got the grey mags. ordered black but the grey look really good with the grey dust cover and little trim pieces. but these mags hold right around 150+ some will load up to 155-163 bbs. this mags fit all of my M4s except for my sons Cyma m4 CQB. the feeder doesnt line up with the hopup tube.
Pros
looks great
feeds reliable
light
durable
easy to clean
clear internal for easy tracer unit build

Cons
bottom screw will strip out if dropped hard
will fit certain model M4s

"I have a very picky hop up and gearbox (Gate EON for both, with a 48k brushless.) Between the high rate of fire and narrow hop up feed of the Gate EON, finding magazines that work have been a chore.

These magazines, however, are perfection. Tight in the mag well. Decent capacity (even though there are now 250+ mid caps). But most importantly they feed flawlessly right out of the box even in my picky replica.

"Exceptionally good magazines. Not that much more to be said. Would for sure recommend to anyone.

Pros-
-Feed well
-Look amazing
-Feel good and sturdy
-Durable
-Nice and noticeable click when you insert in in your gun
-Stays in the gun and doesn't wiggle out
-Literally pretty much everything
-Consistently leaves only 1 bb left after you can't shoot anymore (pro or con)

Cons-
-Only con is that on some guns it might wiggle slightly
