Love the shake & wake feature. solid construction & bright red dot under the sun. - ADE Advanced Optics Zantitium PRO Series Motion Awake Red Dot Sight

The ADE RD3-15 Pro micro red dot with picatinny mount works well on my Buckmark along with the picatinny mount. I like the 3 choices for reticle selections. It makes target shooting more fun because it allows me to have different options for different targets and distance. The red dot is very bright indoor even when it is at level 3 brightness, but it needs to be at least level 6-7 when using it outdoor. I really like the shake awake feature the most because the red dot will always be ready instantly and it also saves battery life if I forget to turn it off. The only unusual thing is I need to hold on to the "down" button for 3 seconds to turn the unit on and off instead of the usual up button like other major brands. I will update how well it holds zero-in after a few thousands live rounds.
