Overall, the quality of it it exceptional. This is my first order from this company, and the prices and shipping were excellent, I admire the company. This has four slots for your AK pin to notch into for timing the muzzle device. The thing I didn't like, was each slot times the muzzle device completely different. One slot was in between two of the flash ports, one was near the middle of one of the flash ports, but not right in the center, and the other two detents were a fraction in between. The other thing I did not know was how thin the metal is on this. Looking at the tip of it and comparing it to a standard AK slant brake, the metal is about 1/3 the thickness of a standard brake. I have not had any issues. I did want something more robust though. I have no other gripes to mention, it seems to go well with the firearm. Just wanted to point out some things I didn't know when I bought it. Thanks for reading.
