Bad detent - NcSTAR Ak Muzzle Brake-Threaded

I wasn't as lucky. Mine has the detent notch cut a degree or two off from center, putting the upper vents and bridges at the front off to the left, visibly. Edges are rough, the flange surfaces at the front, where the gases from the front vents are supposed to push against, are flat not angled like the Tapco or original brakes. Has a little wobble once installed, unlike the factory (useless) piece that came with my Polish Hellpup pistol. At least the finish looks nice, almost a dark blued look. Waste of $8, I'd be more disappointed but I saved a bunch of $$ on the other stuff I ordered and Optics Planet shipped it quickly and free. Caveat Emptor.
