I was wondering if anyone used a red dot sight on there shotgun. I was thinking about mounting one on my work 870. Pros and Cons? Time it takes to turn it on when I need it (jumping out of the car)? I look at a 870 as a 30yrd weapon with 00 buck. I see that TruGlo makes a TFO front sight for the 870 for like $80, a better option? Wanna kill these ads? We can help!
