Replacement Parts - Compatibility

Anyone know which magazine releases fit the K1/K2 receivers? Is the catch between V2-3/LDT and JM 8/9 the same or are they sized differently?

I’m looking to replace the stock orange magazine release with a black one. I’m not keen to paint it as it’ll wear off.

Monkey mods have alternatives I think

Thanks @Smiley have seen. I’m pretty much looking to just replace the stock orange one with a black one, don’t need ambidextrous features. The concern is different width catches on each vendor, they might not be compatible with the magazine.Thanks anyway.
