Tippman TMC Magazine
TMC magazines are probably the simplest, most reliable and cheapest magazines available in paintball magfed sports.
You can even trade premium paint without crushing it and withstand multiple drops.
The TMC magazine is quickly accessible through an inspection flap at the bottom edge of the magazine to remove dirt and paint residue.
In terms of price, at around €25 each, they are simply the top product when it comes to the quality and durability of mags.
A little tip: do not stretch the springs of the mags too much, otherwise the springs can get jammed.
