OTA for Gladiator NXT/EVO Compatibility Question

[CRAKerns]

Hey there,

So to preface this, I understand this might be a question with an obvious answer and I am just oblivious.

Anyway, I was recently "window" shopping through the sight when I saw the preinstalled version of the OTA , then quickly found the stand alone adapter. So I bought a pair of Gladiators a bit over a year ago and wanted to know (Since the release of EVO) if the OTA is compatible with my slightly older version of the base and stick?

Thank you for any assistance and your time.

Those Gladiators of yours, are they NXT or K? Because NXT and K needs different connector for the OTA.

[CRAKerns]

They are both NXT

Then you would need this OTA.
