    As a new AR15 owner, this seems pretty solid so far. As usual quickly shipped and great customer service from BTO.

  2. Mervyn (verified owner)

    Received order quick. Great red dot for my ar9 pistol.

  3. rhewitt (verified owner)

    Holosun makes another solid sight. The green dot is clear and crisp.
