AR15 carry handle sights are durable, practical, and versatile, but leave much to be desired in the optics mounting category. With this McMaster black oxide steel thumb screw, you can easily attach our Primary Arms Prism Scopes to the carry handle to increase your medium range capabilities. The head of the thumb screw is knurled to make tightening it down with your fingers easy and will make sure your optic is rock solid to retain zero. This screw only works with Primary Arms 2.5X, 3X, and 5X prism scopes.
