I just picked up this KJ works m9a1 replica, and it has a integrated rail on it. I was wondering what would be a good option for it. Im looking for laser, more than a flash light, but anything that has worked for you.Also, if you have any other suggestions, like fiber optic sights or enhancements, let me know. And yes i searched, but its hard to google trusted opinions, so if you feel like flamming, then well don't.
