Review: Not for Kimber Customer 2 - Very good quality. Packaged well. Delivered quickly. Unfortunately would not work on my Kimber. Ordered the ADE base for a different dovetail but still wouldn’t work on the Kimber. Very sad about that! Not the product’s fault!!! Added this set up to my Dad’s Sig Sauer instead and it works awesome!! Highly recommend this sight for a high quality budget red dot!!!
Review: Quit working in 2 months - Worked great until it didn't. Pros: Perfect mount for my Springfield 1911 Milspec, looks like it is a stock part of the weapon. Clean, crisp red dot. Held zero well Docter lug set up Single button for simple operation. Glass optic and metal body. Cons: Sight needs to be removed from the weapon to change battery. Mounting screws are soft and heads stripped out after changing the battery twice. Single button constantly changes brightness setting when powering on or off. Stopped functioning after 500 rounds. Not a bad red dot. Unfortunately it quit working. Ade Optics carries a 1 year warranty, but paying shipping both directions for repair/replacement is hardly worth it. The fact that it stood up to even 1 round on top of a 45 slide impressed me.

## Features

- COMPATIBLE WITH 1911 STANDARD AND PICATINNY RAILS – Includes a mounting plate for 1911 with Colt G.I Standard Rear Sight and a universal Picatinny adapter. To use, remove your rear sight, replace with this plate securely, and attach the optic for a firm, reliable connection every time.
