Edge to edge clear red dot. - Vortex Defender-CCW 1x25mm Reflex Red Dot Sight

Mounting was easy, it came with several different sets of screws so I could pick the correct thread pitch, diameter and length. It also came with a 1deg. mounting plate. I fits perfectly with the plate which puts the dot closer to mid range in the vertical adjustment. It also came with a pickitinny adapter. I checked the parallax, the dot aligned with the target and stayed crisp inside the viewable area of the sight. I like the battery placement, no need to remove the sight to replace the battery.
