Quality mount but.... - Leapers UTG Pro Super Slim T1 Mount, Lower 1/3 Co-Witness

Let me start with the Pros because there's more of them than Cons. Great fit and finish. This mount is built really well. I have a Lower 1/3 Reptilia Mount on my other rifle, but want to try something different and roll the dice at a lower price point. It came with five new screws and two T style allen wrenches. Again, I cant stress enough on how well the fit and finish are on it.
Here is the Con. I mounted a Holosun 403B, which married up to the mount perfectly. I'm using Magpul MBUS, front and back. When I flip up the sights the mount blocks the line of sight. The mount is to tall. If you're going to run just a mount/dot combo, then I highly recommend this mount. If you plan on running back up sights in conjunction, you may be out of luck.
