[QUOTE="J E Custom, post: 1524096, member: 2736"] +1 Any system needs to be checked after final installation. I once found a brake that hurt the accuracy and the guy brought it by for me to remove it. The first thing I did was to try my .30 cal mandrel before I removed it. the bore in the brake would not allow the mandrel to go in and after measuring the bore hole I found that the muzzle brake bore had a .308 bore diameter, not a .328 bore for .020 thousandths clearance. The bullet was striking the break every time and shaving copper jacket material. I offered to bore it out for him until I unscrewed it and found tons of Loctite to make up for sloppy threads. I had to replace the brake and cut and re thread the barrel tenon, The last time I heard from the rifle was shooting sub 1/2 moa and he was very happy with it. he was mad that he had to pay twice to get it done right. (I did cut him a brake and only charged him the cost of the brake). My lesson out of all of this is/was to check every re do while the owner is there so he understands what he has and to do a final check in front of the owner as he receives it for his own piece of mind J E CUSTOM [/QUOTE]
