ARMS #40 Stand Alone Flip Up Rear Sight (SEPA)

I have this new in the box (still in wrapping) never put it on my AR-15.

Description:
The unique design of the spring loaded rear sight ensures constant in battery action and repeat zero. The sight is held in the locked down position by a quick release lever, that prevents the sight from being accidentally engaged, but is as fast as a trigger to release even with arctic mittens. Has military horizon line notch, 500-600 meter sight. Windage adjustments .75 MOA

I can send pics to an email adderss upon request.

$90 shipped.
