Does anyone know if any tri lug adapters index correctly of the EVO carbine threads.

My wants for my Scorpion carbine are a tri lug adapter, HK style tri lug flash hider, and SiCo Octane tri lug attachment.

Anyone running Octanes with direct threads? I know their was some possible issues with the threads.

Here is a TROS 3-Lug Adapter with an AAC 3-Lug Flash Hider:

You don't index a 3 lug, you just lightly torque it on with a drop of Loctite. If you want one that works on the outer metric treads there are several adaptors out there but they add quite a bit of length. If you have 1/2 x 28" threads on yours you can just get on that attaches to those. I use a Griffin 3 lug and module on a Rev 45.

Regarding the Silencerco Direct Thread Mount..the 18x1 works really well with the Omega 9K.  The added length is much shorter than a 3-Lug adapter and the Silencerco 3-Lug mount or even the shorter Rugged 3-Lug mount.   Below is a pic of the Omega 9K with the 18x1 Direct Thread Mount:

If you have the newer model with the 1/2x28 threads, then any good 3-lug adapter in that thread pitch will work.    

The weapon includes a very short thread protector for the 18mm outer threads that is held on by the muzzle device detent; you'll want to put that on first, I don't think it will clear the lugs on the 3-lug.
