So I have a Tikka chambered in 300winmag that I had @Velzey Cerakote and thread. He did a fantastic job the gun looks great and the threading is nice. However, being that I am an idiot I didnt bring along my SiCo ASR muzzlebrake that I was planning to put on the gun when I dropped it off and asked him to thread my rifle to the same pattern as a SiCo brake he might have had laying around. The thredding happened to be 1/2 x 28. Which to my chagrin is not the correct pattern for the brake I have. So I am on the search for a muzzlebrake that is a 1/2 x 28 thread but for a 30cal. All the ones I have come across are for .224. I really hope someone here can point me in the correct direction.
