    Question for you guys. I have a Smith and Wesson M&P AR, that I received a Tasco Red Dot for Christmas. I still have the Military style front sight post, so to get the red dot to be useful, I had to use a UTG riser. SO... with the MBUS REAR sight from Magpul, mounted BEHIND the red dot, I can't utilize the rear sight, unless it's laid down, and then the sight apertures are flipped up. Is that still accurate as it sits, or do I have no option but to ditch the MBUS sight?

    I'd like to still use the MBUS if possible, it seems it would be accurate this way as well...
