Command arms front and rear flip up sights - Command Arms Accessories Set of Front and Rear Flip Up Sights

These sights are adequate but could be better. You need to be careful when you change the aperature setting on the rear sight because if you do not hold the windage adjustment knob when doing this, it will turn and change your zero. Instructions were not included with the sights. This could be a problem for someone who is not familiar with mounting or adjusting them.
