Are these sold commercially? Where can I get one for the 17?

UPDATE: instead of started and new Thread, I updated this one. I have a new question regarding the ECP flash hiders.

I was was able to locate an ECP flash hider for my 17 and need some install advice. I couldn't really find much info with the search on the FH
1. Any shims or jam nuts required?
2. Is indexing required? Should one of the prongs be in a specific location?
3. What torque spec should be applied to the FH?
4. Is rocksett requires?
5. If rocksett is used, what to use to clean the threads before applying rocksett
6. Any other tips

I have both .223 and .308 ECP flash hiders I would be willing to part with if anybody is still looking for them, just shoot me a PM. Never used, just some marking from removal. It took quite a bit of force with all of the thread locker they use on the factory SBR barrels.
