Very cheaply made. - OpticsPlanet Exclusive Strike Industries Micro 9mm QUAD V Threaded Compensator

This is a very cheaply made product. It came in a cheap cardboard box with no padding or anything. I bought a torque wrench just to install this comp and set it to 30 in/lbs. The company's torque is value 35 in/lbs but I didn't want to over tighten it. The bolt broke before even reaching 30 inch/lbs. This is supposed to be a brand new product. The comp is dirty and and seems to have gun powder residue on it. I think they sent me a returned product. Either way, it was not built with quality.
