I have been asked to post the following on some sites and want to see if the pricing is close. I have photos of the sights. Thanks!

The Trijicon RMR Dual-Illuminated Red Dot Sight was designed to improve precision with any firearm. This small sight is extremely durable with its forged aluminum housing, and it features audible click adjustments for windage and elevation. The sight is also very versatile as it can be used alone or mounted on an ACOG sight. Dead batteries will never be a worry as this sight is completely battery free; fiber optics and tritium provide all the illumination for this sight
Some damage on the side but works great. $400

Knights armament company 600m micro rear sight assembly. Still in the bag never used. I have 4 to get offer. Thinking around $100 out of each of them. Not sure what the price they have been going for.

Ar 15 carrying Handel iron sights. Asking $25 for it. I have 3 of them
The RMR also has a LaRue quick detach with it.
