Fastfire 3 problem

[Heeter]

I mounted the speedbead and fastfire 3 a week ago on my 870 and everything worked perfect. But this morning a buddy and I doubled up and I noticed my site was was off, so when I got home I sighted it in again and after every shot the dot would be in a different spot. Has anyone had this problem or know anything I can do about it.

Call customer service ASAP. I hunted with the FF-III for the first time this year and have had no problems so far.

Take it with your hand and see if it wiggles left and right...depending on your method of mounting, the mount could be loose or the ff3 loose from the mount. I have the marlin 336 mount drilled and tapped on a benelli and mine did the same thing. Put a tiny dap of locktite on the screws, retighten, and go hunting.

Andy on here had same problem. Something about the way it mounts is causing the problem they decided.

That may be the problem I went through and tightened everything back up and there was one of the mounting screws on top that was a little loose hopefully that will fix it but Ill update this week after i shoot it again

My 870 isnt drilled so I would just switch to that but now its to late since season is in full swing
