Spider red dot optic - Black Spider Optics M0129 Micro Red Dot Sight, 3 MOA

I love this optic! Great price! It has taken loads of abuse, and the water resistance is great. I didn’t say waterproof!! Extremely bright and so easy to use a Marine could do it after he or she eats a 12 pack of crayons. Once the optic is mounted the optic center sits 38.5 mm so keep that in mind if you are going to use a optic magnifier. Also I absolutely love that it uses a single AAA battery and I don’t have to go searching local stores or the web for a special battery. I absolutely recommend this Optic to anyone! Semper Fi!!
