Vortex-9 on ar15 9mm?

[mospeada]

I'm looking at completing my AR15 9mm this week and I've got a Gemtech Vortex-9 and I'd like to attach that to the AR. The issue is that the Gemtech has 1/2-28 threads and the AR has 1/2-36 threads. Does anyone make an adapter for this?

Yes. I had one made for an old jäger .22. Cost me 25 dollars and quality is top notch. I can give you the guys number if you want. Let me know
