Got a Speed Bead on my primary turkey gun, a SBE II. I haven't missed since I added it. I love the low profile and the fact that it doesn't throw the balance of the gun off. I had a conventional red dot on my old SBE, but it was bulky and in the way. It also ate batteries up. I've had the FF ii on a Speed Bead mount for 6 years and have only needed to replace the battery once. I hate they don't make a Speed Bead mount to fit a 20 gauge 870, because I really don't want to drill & tap may Grandad's old Wingmaster.
