At some point in the last 4-5 years, I believe someone mentioned a “cross compatible” muzzle device solution, I believe it was to use a 7.62 can on a 5.56 rifle.

That said, is there any option if I’d like to use a 5.55 QDC on a 5.55 gun with 5/8x24 threads?  I haven’t been able to find anything.  Figured I’d post here before deciding to just use a Surefire on this particular rifle.

I have heard that it's a thing they are working on. No real mention of timeline or anything but that does seem to be on their radar.

I use my 30 cal omega on everything,  just have quick mounts on various 5.56, 6.5cm, 308, 300 win mag rifles

Thanks. That would be tight. I would love to use a CRS on this rifle.  I just wasn’t sure if there was a more current solution that I couldn’t find.

Is it possible they dont make this to prevent anyone from accidentally putting a 556 can on a 762 gun?

They can stamp them or mark them or something. Anyone who makes that mistake would get told that's their problem.

From what I’ve found, I may have been thinking of a 1/2x28 muzzle device to allow use of a .30 cal suppressor on 5.56 rifles.

Yep - exactly what I was referring to. Just no 5/8x24 for the 5.56 cans. Mis-remembered.
