    Ordered this for my first AR and It arrived in really great shape and really fast too. It is a little on the heavier side but if you don’t mind and are looking for genuine surplus or to add this to an A4 clone then this is for you.

  2. sean (verified owner)

    Excellent rail for your M16A4 clone setup, came well packaged and with incredible speed, I am impressed! Will recommend to others and I will be back as a happy customer.
