"Finally got a chance to battle sight zero the MBUS sight on my AR-15. The Magpul sight is well built and durable leaving little doubt that can withstand rough duty. I only needed the rear sight as my front sight is the fixed post. I had no problem getting the weapon zeroed in short order and I found the left right adjustment knob easy to use. The only complaint I have is that I wish the sight was easier to switch from the small aperture to the large. It can be difficult to fold down. Other than that this a another fine product from Magpul"
