Typical lantac disappointment - LANTAC Dragon Muzzle Brake with Dead Air KEYMO suppressor mounts

Bought this to mount a keymo suppressor on. I've dealt with Lantac before....never been super impressed with their products. Decided to give this a shot.....remembered immediately why I don't like Lantac. Supposedly "nitrided" but looks like phosphate. Either its not nitrided or they dont know how to nitride. Compared this to the dead air keymo brake and this one has less area for the keymo qd to clamp down on.....doesnt fit the keymo QD as easily and also is smaller in diameter than the dead air brake. This part also cost double what other keymo brakes costs. No clue why people rave about Lantac.
