That was my guess as well since its the 6.5 Grendel forum, but I thought I would ask the obvious question. I have seen somewhere of small vendor who machines muzzle thread adapters... can't find it right now.

Huges Precision. I bought a 1/2-28 to 5/8-24 adapter for my Tikka 308 from them for about $20. Excellent work. In fact, they are my first stop when I'm looking for such an item. Luckily, a 1/2-28 to 5/8-24 is not an odd ball. I recently bought a 1/2-20 to 5/8-24 for my Steyr Scout in 6.5CM. I finally ended up ordering it directly from Gunsite.~Riuma
